MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded URLs pointing to a single domain, identified by the PDF_SEO_LINK_FARM heuristic. While no scripts were explicitly extracted, the ML classifier flagged the PDF as malicious, and the embedded URLs suggest an attempt to redirect users to potentially malicious content or engage in SEO manipulation. The presence of embedded URLs within the document body, even if obfuscated, indicates an attempt to control user navigation.

Heuristics 2

  • 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.
  • 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.
