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

The PDF contains a large number of embedded links to external URLs, as indicated by the PDF_SEO_LINK_FARM heuristic. While the ML classifier also flagged this PDF as malicious, the specific URLs extracted are currently marked as confirmed benign. The document body is unreadable, and no scripts were extracted. The primary attack pattern appears to be the creation of a link farm, potentially for SEO manipulation or to redirect users to malicious content hosted on other sites.

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.
