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

The PDF contains a large number of external links, many of which are dynamically generated and point to PDF files, indicating a link farm or SEO manipulation tactic. The document body, though partially corrupted, suggests a lure related to 'Canis canem edit' (Bully), possibly to disguise the malicious intent. The primary heuristic firing indicates a mass of external PDF links, suggesting the document's purpose is to drive traffic to these external sites, which could host further malicious content or phishing pages.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
