MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily corrupted, the presence of numerous external links suggests a malicious intent, possibly for SEO manipulation or to distribute further payloads. No scripts were extracted, but the structure implies an attempt to redirect the user through these links.

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.
