MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links pointing to external PDF files, a technique often used for SEO spam or to distribute further malicious content. While the document body is unreadable, the heuristic 'PDF_SEO_LINK_FARM' strongly indicates this malicious intent. The ML classifier also flagged the PDF as malicious. The embedded links are likely intended to lead users to download or view malicious content, potentially as part of a phishing campaign.

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.
