MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, containing a single image and minimal text, typical of phishing attempts. It links through a URL shortener to an external site, which is a common tactic to obscure the final destination. No scripts were extracted, but the document structure and heuristics suggest an attempt to redirect the user to a malicious site.

Heuristics 3

  • Image-only PDF lure links through URL shortener high PDF_IMAGE_LURE_SHORTENER_LINK
    PDF is image-heavy with little real text and its clickable action points to a URL shortener. This is a high-confidence credential-phishing carrier shape: the visible page is a screenshot-like prompt while the destination is hidden behind redirect infrastructure.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 39 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
