MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as a lure, containing only images and a clickable action designed to resemble a screenshot. This action links to a file-hosting service, suggesting an attempt to deliver a secondary payload. The document body was not sufficiently readable to determine specific content, but the heuristics strongly indicate a phishing or malware delivery attempt.

Heuristics 3

  • Image/button lure links to file-hosting download high PDF_FILE_HOSTING_DOWNLOAD_LURE
    PDF is an image-only or near-image-only lure with a clickable action to a public file-hosting download endpoint. This is a common malware delivery pattern: the visible page is just a screenshot/button, while the real payload is fetched from the external hosting service.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 35 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.
