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

The PDF file contains a large number of embedded links to external websites, as indicated by the PDF_SEO_LINK_FARM heuristic. While the document body is heavily obfuscated, the presence of numerous URLs suggests a malicious intent, possibly for SEO poisoning or to redirect users to malicious sites. The ML classifier also strongly indicated maliciousness. No scripts were extracted, and the primary attack vector appears to be the manipulation of external links within the PDF.

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.
