Babuk2

MITRE ATT&CK does not currently catalogue Babuk2, so this is our assessment of the techniques it uses, drawn from public reporting. The techniques themselves, and every "what that means" definition below, come from MITRE ATT&CK v19.2. Confidence: medium. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: babuk2 uses PowerShell scripts to execute malicious commands and deploy ransomware payloads across compromised systems.

   What that means: Adversaries may abuse PowerShell commands and scripts for execution.

2. T1112 Modify Registry PersistenceDefense Impairment

   What they do: babuk2 modifies Windows Registry Run keys to ensure ransomware execution upon system reboot for persistence.

   What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.

3. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: babuk2 leverages registry run keys and startup folders to maintain persistence across reboots.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

4. T1685 Disable or Modify Tools Defense Impairment

   What they do: babuk2 disables security tools like antivirus software and monitoring agents to evade detection during infection.

   What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.

5. T1688 Safe Mode Boot Defense Impairment

   What they do: babuk2 manipulates boot sequence via Safe Mode Boot techniques to bypass initial security checks during execution.

   What that means: Adversaries may abuse Windows safe mode to disable endpoint defenses.

6. T1027.013 Encrypted/Encoded File Stealth

   What they do: babuk2 encrypts and encodes victim files with custom ransomware keys to ensure irreversible data access denial.

   What that means: Adversaries may encrypt or encode files to obfuscate strings, bytes, and other specific patterns to impede detection.

7. T1070.004 File Deletion Stealth

   What they do: babuk2 deletes Volume Shadow Copies and backup files via system commands to prevent data recovery.

   What that means: Adversaries may delete files left behind by the actions of their intrusion activity.

8. T1018 Remote System Discovery Discovery

   What they do: babuk2 discovers remote systems via network scanning to expand foothold across victim networks.

   What that means: Adversaries may attempt to get a listing of other systems by IP address, hostname, or other logical identifier on a network that may be used for Lateral Movement from the current system.

9. T1135 Network Share Discovery Discovery

   What they do: babuk2 performs network share discovery to identify accessible SMB shares for lateral movement and victim targeting.

   What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.

10. T1021.002 SMB/Windows Admin Shares Lateral Movement

    What they do: babuk2 uses SMB/Windows Admin Shares for lateral movement between compromised hosts within the network.

    What that means: Adversaries may use Valid Accounts to interact with a remote network share using Server Message Block (SMB).

11. T1486 Data Encrypted for Impact Impact

    What they do: babuk2 encrypts victim files using strong symmetric encryption to maximize impact and trigger ransom demands.

    What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.

12. T1490 Inhibit System Recovery Impact

    What they do: babuk2 calls system recovery inhibitors like shutdown scripts to prevent victim systems from restoring functionality.

    What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.
