MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF document contains a large number of embedded links to external websites, as indicated by the PDF_SEO_LINK_FARM heuristic. While the specific content of the document body is heavily obfuscated, the presence of numerous links suggests an attempt to direct users to potentially malicious or spam-related content. The ML_NYX_PDF_MALICIOUS heuristic further supports the malicious nature of the file. The primary attack pattern appears to be a link farm designed to distribute traffic or host malicious content.

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.
