MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF was flagged by a critical heuristic for containing a large number of external links, forming a link farm. While the extracted URLs themselves are classified as benign, the sheer volume and structure suggest a malicious intent to manipulate search engine rankings or redirect users to potentially harmful content. The ML classifier also strongly indicated maliciousness.

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.
