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

The PDF was flagged by a machine learning classifier and a critical heuristic for containing a large number of external links. These links point to various PDF documents on the same domain, suggesting a link farm or a distribution point for other malicious files. The document body itself appears to be malformed or heavily obfuscated, preventing a clear understanding of its direct intent beyond the link farm.

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.
