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

The PDF file exhibits characteristics of a link farm, embedding a large number of external URLs. The heuristic 'PDF_SEO_LINK_FARM' indicates that these links are likely intended to redirect users to malicious sites, potentially for phishing or malware delivery. The ClamAV detection further supports its malicious nature. No scripts were extracted from this sample, and the document body contains a mix of text and URLs, reinforcing the link-based attack vector.

  • 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.
