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

The PDF contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, which is a common technique for distributing malicious content or leading users to phishing sites. The ML classifier also strongly indicated maliciousness. While no scripts were extracted, the sheer volume of links and the nature of the heuristic suggest a link-farming attack pattern designed to lure victims. The URLs themselves appear to be part of this link farm.

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.
