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

The PDF file was flagged by multiple heuristics, including ClamAV and an ML classifier, indicating malicious intent. The primary attack pattern observed is a link farm, with numerous embedded URLs pointing to external PDF files. The document body contains seemingly random text and URLs, suggesting it is designed to evade simple content analysis while serving as a vehicle for these links. The presence of many external links strongly suggests a phishing or redirection attempt.

  • 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.
