MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious File

The PDF file was flagged by a machine learning classifier as malicious and contains a large number of external links to other PDF documents hosted on the same domain. This behavior is indicative of a link farm or a distribution mechanism for further malicious content, potentially aiming to manipulate SEO or deliver malware. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure.

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.
