MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file was flagged by a machine learning classifier as malicious. It contains a large number of embedded external links, a technique often used for SEO poisoning or to redirect users to malicious sites. The primary heuristic indicates a 'PDF_SEO_LINK_FARM' with 32 external links, suggesting a campaign to distribute malicious content or phishing lures through a network of linked PDFs. The document body is heavily corrupted, preventing analysis of its specific content, but the link farm and ML classification strongly suggest a malicious intent.

Heuristics 2

  • 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.
  • 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.
