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

The PDF document contains a large number of external links, a common tactic for SEO poisoning and directing users to malicious sites. The document body, though partially corrupted, contains text related to 'Kali linux' and penetration testing, suggesting a lure to attract users interested in such topics. The heuristic 'PDF_SEO_LINK_FARM' confirms the presence of a link farm, indicating a malicious intent to distribute links to potentially harmful content.

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.
