MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The ML classifier strongly indicates maliciousness in this PDF. The presence of an embedded file and an AcroForm button with an action trigger suggests an attempt to deliver a payload or initiate a malicious action upon user interaction. The document body is heavily obfuscated, preventing a clear understanding of the lure, but the overall structure points towards a phishing or malware delivery attempt.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9986

Heuristics 4

  • Embedded file low PDF_EMBEDDED
    PDF embeds a file attachment — could carry an executable or another weaponised document as a nested payload
  • XFA form low PDF_XFA
    PDF uses XML Forms Architecture — can contain script logic
  • AcroForm button with action trigger low PDF_ACROFORM_BUTTON
    PDF contains a /Btn form field together with a SubmitForm/URI/Launch/JS trigger — this is the building block of fake 'Download' or 'Open' button overlays used in PDF phishing lures
  • 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.
