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

The file is identified as a malicious PDF by ClamAV and an ML classifier. Heuristics indicate the presence of embedded content and remote actions, suggesting it's designed to deliver or execute further malicious code. The embedded PDF child and remote GoTo actions are particularly suspicious.

Machine Learning

  • Nyx PDF Classifier malicious score 0.8662

Heuristics 5

  • Embedded PDF child has suspicious static findings critical PDF_EMBEDDED_CHILD_STATIC_TRIAGE
    PDF contains an embedded PDF stream whose extracted child matches suspicious or malicious PDF heuristics. Wrapper PDFs are commonly used to hide the actual exploit or lure payload from scanners that do not recursively inspect attachments.
  • ClamAV: Pdf.Dropper.Agent-7246962-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Dropper.Agent-7246962-0
  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • Remote GoTo action info PDF_GOTO_REMOTE
    PDF has GoToR/GoToE actions that reference sibling document files — typical of multi-part document bundles
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
