T1566.002 Spearphishing Attachment T1204.002 Malicious File

The PDF contains a large number of embedded external links, a technique often used for SEO manipulation or to redirect users to potentially malicious content. The ML classifier also flagged this PDF as malicious with high confidence. While the extracted URLs themselves are currently marked as benign, the sheer volume and the heuristic firing indicate a malicious intent, likely to distribute further payloads or engage in phishing. No scripts were extracted from this sample.

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.
