MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains heuristics indicating external URIs and a URL shortener, suggesting an attempt to redirect the user to a malicious site. The presence of an AcroForm button with an action trigger further supports this, as it can be used to execute actions like opening URLs. No scripts were extracted, but the overall structure points to a phishing or malware delivery attempt via a malicious link.

  • Nyx PDF Classifier clean score 0.1679

Heuristics 5

  • Clickable URI uses URL shortener medium PDF_URL_SHORTENER_URI
    PDF contains a clickable HTTP(S) action whose destination is a URL shortener. This hides the final landing page from static review and is common in phishing redirect PDFs.
  • ASCII85Decode filter (with exploit indicators) low PDF_FILTER_85
    ASCII85 encoding filter present alongside exploit delivery indicators — uncommon outside of obfuscation
  • 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
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
