Rabbithole

MITRE ATT&CK does not currently catalogue Rabbithole, 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: rabbithole uses PowerShell to execute malicious payloads and stage ransomware operations on compromised hosts.

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

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

   What they do: rabbithole modifies Registry Run Keys and startup folders to ensure recurring execution after reboots.

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

3. T1685 Disable or Modify Tools Defense Impairment

   What they do: rabbithole disables antivirus tools and security software 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.

4. T1070.004 File Deletion Stealth

   What they do: rabbithole deletes Volume Shadow Copies and backup files to prevent recovery from restore points.

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

5. T1110 Brute Force Credential Access

   What they do: rabbithole brute-forces local accounts to gain initial access and persistence on systems.

   What that means: Adversaries may use brute force techniques to gain access to accounts when passwords are unknown or when password hashes are obtained.

6. T1018 Remote System Discovery Discovery

   What they do: rabbithole performs remote system discovery to map the victim environment before deploying payloads.

   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.

7. T1049 System Network Connections Discovery Discovery

   What they do: rabbithole queries system network connections to identify active services and communication paths for exfiltration.

   What that means: Adversaries may attempt to get a listing of network connections to or from the compromised system they are currently accessing or from remote systems by querying for information over the network.

8. T1135 Network Share Discovery Discovery

   What they do: rabbithole discovers network shares to identify additional systems for lateral movement and data 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.

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

   What they do: rabbithole uses SMB/Windows Admin Shares to spread ransomware across networked systems.

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

10. T1486 Data Encrypted for Impact Impact

    What they do: rabbithole encrypts victim files and data using strong symmetric encryption to maximize impact.

    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.
