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

The PDF file was identified as malicious due to a critical heuristic firing for a PDF SEO link farm. It contains 32 external links, predominantly to PDF files hosted on www.gorillawalker.com. The document body is heavily obfuscated and unreadable, providing no direct clues to its intent. The primary attack pattern appears to be the distribution of numerous links, likely to redirect users to malicious content or for search engine optimization purposes.

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.
