MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded links, identified as a link farm, which is a common technique for distributing malware or directing users to phishing sites. The ML classifier also strongly indicated maliciousness. The document body was unreadable, but the presence of numerous links to external PDFs from the same domain suggests a coordinated effort to redirect users.

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.
