MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The document body presents itself as a cheat code resource for Grand Theft Auto V, but the embedded heuristics and URLs indicate a malicious intent to host a link farm of PDF files. The PDF_SEO_LINK_FARM heuristic firing suggests the primary purpose is to distribute numerous external PDF files, likely malicious, through a network of seemingly unrelated websites. The ML classifier and ClamAV detection confirm the malicious nature of the PDF.

  • 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.
