MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF document was flagged by a machine learning classifier as malicious. A critical heuristic identified a large number of embedded external links, suggesting a link farm or distribution mechanism. The document body contains obfuscated content, but the primary malicious activity appears to be the mass embedding of URLs pointing to other PDF files, likely to manipulate search engine results or serve as a lure.

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.
