MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as a phishing lure due to its small size, image-heavy content, and embedded clickable link. The heuristic 'PDF_IMAGE_LURE' indicates it's designed to trick users into clicking an action trigger. The presence of numerous external links, including one to 'trafficel.ru', suggests a malicious intent to redirect users to potentially harmful sites.

  • 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 42 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.

    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.
