MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains a large number of external links, indicating a potential SEO spam or link farm tactic. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document is designed to trick users into believing they need a password for an archive, which is a common social engineering technique to bypass gateway security. The presence of numerous links to PDF files on various domains points towards a coordinated effort to distribute content or redirect users to malicious sites.

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.
  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
