MITRE ATT&CK
T1566.001 Spearphishing Attachment

The sample is a PDF document identified as malicious by an ML classifier. It contains a large number of embedded URLs pointing to external PDF files, suggesting a link farm or SEO manipulation tactic. While no scripts were explicitly extracted, the presence of embedded URLs and the PDF structure itself could be leveraged to redirect users to malicious sites or download further payloads.

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.
