MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as suspicious due to its structure, which resembles a phishing lure with an image overlay and a clickable action. The document body contains multiple URLs, suggesting an attempt to redirect the user to malicious websites for further exploitation. The presence of embedded URLs and the ML classifier's flagging strongly indicate malicious intent.

Heuristics 3

  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 1 text block(s), carries a click-outward action, and is only 165 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
