Reynolds

MITRE ATT&CK does not currently catalogue Reynolds, 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: reynolds executes malicious commands via PowerShell scripts to stage payloads and manipulate system behavior.

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

2. T1685 Disable or Modify Tools Defense Impairment

   What they do: reynolds disables antivirus tools and security software to evade detection during its intrusion.

   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: reynolds deletes Volume Shadow Copies and backup files to prevent recovery and strengthen its leverage.

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

4. T1135 Network Share Discovery Discovery

   What they do: reynolds scans network shares to identify victim hosts and expand its foothold laterally.

   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.

5. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: reynolds exfiltrates stolen data via encrypted channels to enable double extortion against victims.

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

6. T1486 Data Encrypted for Impact Impact

   What they do: reynolds encrypts victim files using a custom ransomware algorithm to maximize impact and extortion.

   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.

7. T1489 Service Stop Impact

   What they do: reynolds terminates critical Windows services and processes to disrupt victim operations before encryption.

   What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.

8. T1490 Inhibit System Recovery Impact

   What they do: reynolds halts system recovery processes and service restarts to ensure encrypted systems remain non-functional.

   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.
