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

The PDF document contains numerous external links, many of which point to potentially malicious files disguised as ebooks or software downloads. The 'PDF_SEO_LINK_FARM' heuristic indicates a large number of these links, suggesting a tactic to distribute malware through search engine optimization. The 'SE_PASSWORD_ARCHIVE_LURE' heuristic suggests that some of these downloads may be password-protected archives, a common method to evade gateway scanning.

Heuristics 6

  • 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.
  • LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMAND
    Extracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
  • 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
  • Remote GoTo action info PDF_GOTO_REMOTE
    PDF has GoToR/GoToE actions that reference sibling document files — typical of multi-part document bundles
  • 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.
