Ms13089

MITRE ATT&CK does not currently catalogue Ms13089, 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: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: ms13089 uses PowerShell scripts to execute malicious commands and payload deployment across compromised systems.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: ms13089 disables security tools and modifies system configurations to evade detection and hinder incident response.

   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.

3. T1070.004 File Deletion Stealth

   What they do: ms13089 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.

4. T1110 Brute Force Credential Access

   What they do: ms13089 employs brute force attacks against local accounts to gain initial access and persistence foothold.

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

5. T1057 Process Discovery Discovery

   What they do: ms13089 runs process discovery commands to identify active processes for targeting or disabling critical services.

   What that means: Adversaries may attempt to get information about running processes on a system.

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

   What they do: ms13089 leverages SMB/Windows Admin Shares for lateral movement between networked hosts within victim environments.

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

7. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: ms13089 exfiltrates stolen sensitive data using encrypted channels to enable double extortion tactics.

   What that means: Adversaries may exfiltrate data to a cloud storage service rather than over their primary command and control channel.

8. T1486 Data Encrypted for Impact Impact

   What they do: ms13089 encrypts victim files using its ransomware payload to maximize impact and extortion leverage.

   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.

9. T1490 Inhibit System Recovery Impact

   What they do: ms13089 invokes system recovery inhibition commands to prevent automatic restoration mechanisms from activating.

   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.
