MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded external links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to a dynamic DNS domain and appear to be part of a link farm or SEO poisoning strategy. While the document body is heavily corrupted, the presence of numerous links suggests an attempt to drive traffic or potentially distribute further malicious content through these external resources. No scripts were extracted from this sample.

Heuristics 2

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • 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.
