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

The PDF contains a large number of embedded external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The ML classifier strongly indicated maliciousness. While the specific intent of the links is unclear due to their benign reputation, the sheer volume and the heuristic firing suggest a malicious purpose, likely related to distributing further malware or phishing content.

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.
