0x00

MITRE ATT&CK does not currently catalogue 0x00, 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 v20.0. Confidence: low. Treat it as orientation, not attribution.

1. T1059.001 PowerShell Execution

   What they do: 0x0x00 executes malicious payloads via PowerShell to stage ransomware operations on compromised hosts.

   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: 0x00 persists via Registry Run Keys to ensure ransomware reactivation after reboot.

   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: 0x00 disables security tools like antivirus and EDR by modifying system processes and services.

   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 Obfuscated Files or Information Stealth

   What they do: 0x00 obfuscates malicious binaries and configuration files to evade static detection.

   What that means: Adversaries may attempt to make an executable or file difficult to discover or analyze by encrypting, encoding, or otherwise obfuscating its contents on the system or in transit.

5. T1070.004 File Deletion Stealth

   What they do: 0x00 deletes Volume Shadow Copies and backup directories to prevent recovery without paying ransom.

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

6. T1083 File and Directory Discovery Discovery

   What they do: 0x00 uses file and directory discovery to enumerate critical system paths and victim data before encryption.

   What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.

7. T1486 Data Encrypted for Impact Impact

   What they do: 0x00 encrypts victim files using strong symmetric encryption to maximize disruption and ransom demand.

   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: 0x00 inhibits system recovery by corrupting restore points and disabling backup 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.
