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 |

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.

Trojanized Xcode Project Slips XcodeSpy Malware to Apple Developers
(published: March 18, 2021)
Researchers from cybersecurity firm SentinelOne have discovered a malicious version of the legitimate iOS TabBarInteraction Xcode project being distributed in a supply-chain attack. The malware, dubbed XcodeSpy, targets Xcode, an integrated development environment (IDE) used in macOS for developing Apple software and applications. The malicious project is a ripped version of TabBarInteraction, a legitimate project that has not been compromised. Malicious Xcode projects are being used to hijack developer systems and spread custom EggShell backdoors.
Analyst Comment: Researchers attribute this new targeting of Apple developers to North Korea and Lazarus group: similar TTPs of compromising developer supply chain were discovered in January 2021 when North Korean APT was using a malicious Visual Studio project. Moreover, one of the victims of XcodeSpy is a Japanese organization regularly targeted by North Korea. A behavioral detection solution is required to fully detect the presence of XcodeSpy payloads.

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.

‘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.

2019-07-25 13:00:00 | Can you trust threat intelligence from threat sharing communities? | AT&T ThreatTraq (lien direct) | Every week the AT&T Chief Security Office produces a series called ThreatTraq with helpful information and news commentary for InfoSec practitioners and researchers. I really enjoy them; you can subscribe to the Youtube channel to stay updated. This is a transcript of a recent feature on ThreatTraq. The video features Jaime Blasco, VP and Chief Scientist, AlienVault, Stan Nurilov, Lead Member of Technical Staff, AT&T, and Joe Harten, Director Technical Security. Stan: Jaime. I think you have a very interesting topic today about threat intelligence. Jaime: Yes, we want to talk about how threat intelligence is critical for threat detection and incident response, but then when this threat intelligence and the threat actors try to match those indicators and that information that is being shared, it can actually be bad for companies. So we are going to share some of the experiences we have had with managing the Open Threat Exchange (OTX) - one of the biggest threat sharing communities out there. Stan: Jaime mentioned that they have so many threat indicators and so much threat intelligence as part of OTX, the platform. Jaime: We know attackers monitor these platforms and are adjusting tactics and techniques and probably the infrastructure based on public reaction to cyber security companies sharing their activities in blog posts and other reporting. An example is in September 2017, we saw APT28, and it became harder to track because we were using some of the infrastructure and some of the techniques that were publicly known. And another cyber security company published content about that and then APT28 became much more difficult to track. The other example is APT1. If you remember the APT1 report in 2013 that Mandiant published, that made the group basically disappear from the face of earth, right? We didn't see them for a while and then they changed the infrastructure and they changed a lot of the tools that they were using, and then they came back in 2014. So we can see that that threat actor disappeared for a while, changed and rebuilt, and then they came back. We also know that attackers can try to publish false information in this platform, so that's why it's important that not only those platforms are automated, but also there are human analysts that can verify that information. Joe: It seems like you have to have a process of validating the intelligence, right? I think part of it is you don't want to take this intelligence at face value without having some expertise of your own that asks, is this valid? Is this a false positive? Is this planted by the adversary in order to throw off the scent? I think it's one of those things where you can't automatically trust - threat intelligence. You have to do some of your own diligence to validate the intelligence, make sure it makes sense, make sure it's still fresh, it's still good. This is something we're working on internally - creating those other layers to validate and create better value of our threat intelligence. Jaime: The other issue I wanted to bring to the table is what we call false flag operations - that's when an adversary or a threat actor studies another threat actor and tries to emulate their behavior. So when companies try to do at | Malware Threat Studies Guideline | APT 38 APT 28 APT 1 | |
