MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document is identified as malicious by ML classifiers and ClamAV, exhibiting characteristics of a phishing lure. The PDF_IMAGE_LURE heuristic indicates it's an image-based document designed to trick users into clicking an embedded URI. The presence of multiple external URIs, some hosted on disposable domains, further supports a phishing or malicious download campaign. No scripts were extracted, but the document's structure and heuristics strongly suggest it's part of a spearphishing attachment campaign.

  • 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 38 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
    Small PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
  • 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.
