TiMc

MITRE ATT&CK does not currently catalogue TiMc, 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: TiMc executes PowerShell scripts to stage payloads and manipulate system processes during initial compromise.

   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: TiMc leverages registry run keys to maintain persistence across reboots in targeted IT and healthcare systems.

   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: TiMc disables antivirus tools and security software to evade detection before executing ransomware operations.

   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. T1027.013 Encrypted/Encoded File Stealth

   What they do: TiMc encodes malicious binaries and configuration data to evade signature-based detection during deployment.

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

5. T1070.004 File Deletion Stealth

   What they do: TiMc deletes Volume Shadow Copies and backup directories via command-line tools to prevent data recovery.

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

6. T1135 Network Share Discovery Discovery

   What they do: TiMc scans network shares using native tools to identify victim hosts for lateral movement across the retail and IT environments.

   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.

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

   What they do: TiMc moves laterally through SMB/Windows Admin Shares to compromise additional servers in e-commerce infrastructure.

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

8. T1486 Data Encrypted for Impact Impact

   What they do: TiMc encrypts critical retail and healthcare files using custom ransomware binaries to maximize impact on business operations.

   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: TiMc halts system recovery processes by terminating critical services and disrupting backup restoration mechanisms.

   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.
