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

This PDF document employs an advance-fee scam lure, presenting language related to lotteries, prizes, and parcel delivery requirements to deceive the user. It contains a mass of external links, many pointing to other PDF files hosted on similar domains, suggesting a link farm or SEO poisoning tactic to distribute the scam. The primary intent is to trick users into engaging with fraudulent schemes by promising financial gains or requiring action for a delivered item.

Heuristics 4

  • 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.
  • Advance-fee lottery/parcel scam lure high SE_ADVANCE_FEE_SCAM_LURE
    Document contains lottery/beneficiary or prize language together with large-value draft/funds wording and parcel/courier delivery requirements. This is a classic advance-fee fraud document shape.
  • 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.
