Hades

MITRE ATT&CK does not currently catalogue Hades, 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: Hades 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. T1685 Disable or Modify Tools Defense Impairment

   What they do: Hades disables antivirus tools and security software using registry modifications and process termination mechanisms.

   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: Hades deletes Volume Shadow Copies and backup directories via system commands to prevent data recovery.

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

4. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: Hades exfiltrates victim data before encryption using network protocols configured for covert data transfer.

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

5. T1486 Data Encrypted for Impact Impact

   What they do: Hades encrypts victim files using its own ransomware binary, locking data for 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.

6. T1490 Inhibit System Recovery Impact

   What they do: Hades runs commands to inhibit system recovery by disabling backup restoration processes and services.

   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.
