MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1204.002 Malicious File: User Execution

The PDF file was flagged as malicious by an ML classifier. It contains a large number of embedded URLs, identified as a PDF SEO link farm. While the URLs themselves are currently marked as benign, the sheer volume and the nature of the heuristic suggest an attempt to manipulate search engine results or to distribute potentially malicious content disguised as legitimate documents. 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.
