MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by an ML classifier and exhibits characteristics of a phishing lure, including a single image and minimal text content. It contains a mass of external links, with the primary URL pointing to a page that appears to be a lure for downloading a PDF. The document body itself is heavily obfuscated and contains multiple URLs, suggesting an attempt to redirect the user to malicious content.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
  • 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 23 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.
