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.

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.

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.
