MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file was flagged by a machine learning classifier as malicious and contains a large number of embedded links. The heuristic 'PDF_SEO_LINK_FARM' indicates that these links are likely part of a scheme to manipulate search engine results or distribute further malicious content. While the specific intent of the links is unclear due to their 'confirmed_benign' reputation, the sheer volume and the critical heuristic firing suggest a malicious purpose.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
