MITRE ATT&CK
T1204.002 Malicious File T1059.001 PowerShell

The PDF file is encrypted and contains an OpenAction that triggers a launch action. The heuristic PDF_LAUNCH_COMMAND indicates that the launch action targets a specific, albeit obfuscated, command. This suggests the document is designed to execute a malicious payload upon opening, likely to download and run further malware. The encrypted nature and launch action point towards an exploit delivery mechanism.

Heuristics 4

  • /Launch action target: �Tv�����#qZ���\(ߦ�\\���|�Iw" hie critical PDF_LAUNCH_COMMAND
    PDF /Launch action specifies an executable target — references a known-dangerous executable (cmd, PowerShell, etc.).
  • OpenAction trigger high PDF_OPENACTION
    PDF has an /OpenAction that launches, submits, or opens an external target
  • Launch action high PDF_LAUNCH
    PDF contains a /Launch action with an unresolved or extension-less target — treat as potentially dangerous
  • Encrypted PDF carries /OpenAction — payload hidden from static analysis high PDF_ENCRYPTED_WITH_JS
    PDF declares /Encrypt and also references an executable trigger (/OpenAction). Document encryption hides the JavaScript body and stream contents from static scanners — combined with auto-execution indicators this is a known evasion pattern used to deliver weaponised JavaScript that the analyst cannot inspect without the decryption key.
