Phoenixcryptolocker

MITRE ATT&CK does not currently catalogue Phoenixcryptolocker, 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: phoenixcryptolocker executes malicious payloads via PowerShell scripts injected into legitimate processes.

   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: phoenixcryptolocker establishes persistence by adding malicious entries to Windows Registry Run Keys.

   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: phoenixcryptolocker disables antivirus tools by terminating security processes and modifying service configurations.

   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: phoenixcryptolocker deletes Volume Shadow Copies and backup directories via vssadmin and command-line tools.

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

5. T1135 Network Share Discovery Discovery

   What they do: phoenixcryptolocker scans network shares using net share commands to identify victim file servers.

   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.

6. T1567.002 Exfiltration to Cloud Storage Exfiltration

   What they do: phoenixcryptolocker exfiltrates stolen financial and legal records before deployment to extortion.

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

7. T1486 Data Encrypted for Impact Impact

   What they do: phoenixcryptolocker encrypts victim files using strong symmetric encryption algorithms targeting critical business data.

   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.

8. T1490 Inhibit System Recovery Impact

   What they do: phoenixcryptolocker halts system recovery by corrupting restore points and disabling backup 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.
