Donex

MITRE ATT&CK does not currently catalogue Donex, 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. T1059.001 PowerShell Execution

   What they do: donex 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. T1547.001 Registry Run Keys / Startup Folder PersistencePrivilege Escalation

   What they do: donex modifies Windows Registry Run Keys to ensure malware persistence across reboots on infected endpoints.

   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: donex disables security tools like antivirus software to evade detection and ensure ransomware execution proceeds unimpeded.

   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. T1027.016 Junk Code Insertion Stealth

   What they do: donex inserts junk code into binaries to evade static analysis and detection by security monitoring tools.

   What that means: Adversaries may use junk code / dead code to obfuscate a malware’s functionality.

5. T1070.004 File Deletion Stealth

   What they do: donex deletes Volume Shadow Copies and backup files via command-line tools to prevent data recovery without paying the ransom.

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

6. T1135 Network Share Discovery Discovery

   What they do: donex performs network share discovery to identify accessible remote directories for lateral movement and data targeting.

   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.

7. T1560.001 Archive via Utility Collection

   What they do: donex archives stolen victim data using utility tools prior to exfiltration to support extortion demands.

   What that means: Adversaries may use utilities to compress and/or encrypt collected data prior to exfiltration.

8. T1486 Data Encrypted for Impact Impact

   What they do: donex encrypts victim files using strong symmetric encryption, rendering business data inaccessible until payment is demanded.

   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.
