SafeBreach Adds/Updates Coverage for New Malware & Ransomware Variants

The SafeBreach Platform has been updated with coverage for several newly discovered threats including novel malware and ransomware variants. SafeBreach customers can select and run these attacks from the SafeBreach Hacker’s Playbook™ to ensure coverage against these advanced threats. Additional details about the threat and our coverage can be seen below.

Lockbit 3.0 Ransomware

Also known as LockBit Black, this ransomware family announced itself in July 2022 offering the data of its non-paying victims online in a freely available easy-to-use searchable form. It also introduced a bug bounty program to find defects in its ransomware. In September 2022, the builder for the ransomware was leaked and available for download on GitHub. This leaked source allows many new emerging groups to use the same or modified versions of LockBit 3.0 originating from this builder. LockBit continues its rise to the top of the ransomware ecosystem. This ransomware groups adopt a variety of tactics and tools depending on the victims involved in the attack. It mostly gains initial access via compromised servers or RDP accounts that are usually bought or obtained from dark web. In some cases, it is obtained via spam email or by brute forcing insecure RDP or VPN credentials. After gaining initial access, the ransomware propagates through insecure Remote Desktop connections (RDP), SMB, and via the group policy of the domain controller. In some instances, PsExec or Cobalt Strike are used to move laterally within the network. It is usually executed via the command line, scheduled tasks, and PowerShell scripts. Before running the ransomware program, the threat actor exfiltrates data over the C2 channel or uploads to cloud storage using tools like MegaSync, and Stealbit. Upon execution, ransomware encrypts all files one by one inside each folder excluding files with certain extensions that are important to the operating system like .dll, .exe, .sys, .lnk, .reg, .txt. A ransom note file is written inside each folder indicating that their all files are encrypted and a ransom is to be paid in order to restore access.

Venus Ransomware

This ransomware variant (also known as GOODGAME) has been active since August 2022 and has targeted victims worldwide. Threat actors leveraging Venus ransomware are targeting publicly exposed Remote Desktop Services (RDP), including those running on non-standard TCP ports to encrypt Windows devices. Based on the information available, Venus ransomware will attempt to terminate 39 processes associated with database servers and Microsoft Office applications. The ransomware will delete event logs, Shadow Copy Volumes, and disable Data Execution Prevention. When encrypting files, the ransomware uses AES and RSA algorithms and will append the ‘.venus’ extension. In each encrypted file, a ‘goodgamer’ filemarker and other information are added to the end of the file. Open-source reports indicate that initial ransom demands may start around 1 BTC or less than USD $20,000. Samples in the wild have been observed contacting IP addresses in various countries including the US, Great Britain, Denmark, France, Ireland, the Netherlands, Russia, and Japan.

Lorenz Ransomware

The Lorenz ransomware group has been known to target enterprises worldwide since December 2020 with ransom demands ranging in the hundreds of thousands of dollars. The Lorenz gang typically sells stolen victim data prior to encryption to pressure their victims into paying the ransom. They are also known to sell access to victim networks to other threat actors. The group stores stolen victim data in password-protected RAR archives and if the demanded ransom is not paid, Lorenz also releases the password to access the leaked archives to provide public access to the stolen files.

QakBot Malware/ BlackBasta Ransomware

The ransomware group BlackBasta which has been active since April 2022 has been observed targeting U.S.-based companies with the QakBot trojan to gain initial access, move laterally, and deploy BlackBasta or other ransomware in their victim networks. QakBot, also known as QBot or Pinkslipbot, is a banking trojan primarily used to steal victims’ financial data, including browser information, keystrokes, and credentials. Once QakBot has successfully infected an environment, the malware installs a backdoor allowing the threat actor to drop additional malware—namely, ransomware.

IceXLoader Malware

Researchers have discovered a new ongoing phishing campaign that has infected thousands of home and corporate users with a new version of the ‘IceXLoader’ malware. Previous versions of this malware loader have been aggressively promoted among cyber criminals and this new variation/update could see a sudden uptick in its deployment. The infection begins with the arrival of a ZIP file via a phishing email containing the first-stage extractor. Then, depending on the extract settings selected by the operator, the infected system may be rebooted, and a new registry key will be added to delete the temp folder when the computer restarts. The dropped executable is a downloader that fetches a PNG file from a hardcoded URL and converts it into an obfuscated DLL file which is the IceXLoader payload. After decrypting the payload, the dropper performs checks to ensure it’s not running inside an emulator and waits 35 seconds before executing the malware loader to evade sandboxes. To ensure persistence between reboots, the malware loader also creates a new registry key at “HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run.” For evasion, it uses a method of in-memory patching in AMSI.DLL, bypassing the Microsoft Windows Antimalware Scan Interface used by Windows Defender and other security products.
