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

The PDF file was flagged by a machine learning classifier and contains a large number of embedded links, indicating a potential SEO poisoning or link farm attack. While the document body is unreadable, the heuristic 'PDF_SEO_LINK_FARM' strongly suggests the intent is to direct users to external resources. The majority of the extracted URLs are marked as confirmed benign, but the sheer volume and the critical heuristic firing warrant caution.

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.
