0mega

MITRE ATT&CK does not currently catalogue 0mega, 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. T1078.002 Domain Accounts Initial AccessPersistencePrivilege EscalationStealth

   What they do: 0mega exploits valid domain accounts harvested during initial access to maintain persistence and privilege.

   What that means: Adversaries may obtain and abuse credentials of a domain account as a means of gaining Initial Access, Persistence, Privilege Escalation, or Defense Evasion.

2. T1059.001 PowerShell Execution

   What they do: 0mega executes PowerShell scripts to stage ransomware payloads and manipulate system processes.

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

3. T1106 Native API Execution

   What they do: 0mega leverages native API calls to interact with Windows services and evade detection during execution.

   What that means: Adversaries may interact with the native OS application programming interface (API) to execute behaviors.

4. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: 0mega modifies registry run keys to ensure ransomware execution upon system reboot for persistence.

   What that means: Adversaries may achieve persistence by adding a program to a startup folder or referencing it with a Registry run key.

5. T1685 Disable or Modify Tools Defense Impairment

   What they do: 0mega disables antivirus tools and security software to prevent system recovery and hinder incident response.

   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.

6. T1027.013 Encrypted/Encoded File Stealth

   What they do: 0mega encodes victim data with custom symmetric encryption keys before exfiltration or impact.

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

7. T1057 Process Discovery Discovery

   What they do: 0mega performs process discovery to identify critical system processes for termination or manipulation.

   What that means: Adversaries may attempt to get information about running processes on a system.

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

   What they do: 0mega uses SMB/Windows Admin Shares to spread ransomware across networked machines within victim environments.

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

9. T1486 Data Encrypted for Impact Impact

   What they do: 0mega encrypts victim files using its ransomware payload to maximize impact and extortion leverage.

   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.

10. T1490 Inhibit System Recovery Impact

    What they do: 0mega invokes system recovery inhibition commands to block backup restoration and deepen impact.

    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.
