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

The PDF file was flagged by a machine learning classifier and a critical heuristic for containing a large number of external links, suggesting a link farm or SEO manipulation tactic. The embedded URLs point to various PDF documents hosted on the same domain, indicating a coordinated effort to distribute content or potentially lure users to malicious sites. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific 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.
