MITRE ATT&CK
T1059.001 PowerShell T1598 TTPs: Gather Victim Identity Information

The PDF document contains a large number of external links, many pointing to other PDF files, suggesting a link farm or SEO poisoning tactic. The critical heuristic 'SE_SECRET_RECOVERY_LURE' indicates the document explicitly requests sensitive recovery information from the user. The embedded URLs likely serve as part of this lure, directing users to potentially malicious content or phishing pages.

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.
  • Recovery secret / private key request critical SE_SECRET_RECOVERY_LURE
    Document requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
  • 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.
