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

The PDF file contains a large number of embedded links to external websites, identified by the PDF_SEO_LINK_FARM heuristic. While many of these URLs are marked as benign, the sheer volume and the nature of the links suggest a potential SEO spam or content redirection scheme. No scripts were extracted from this sample, and the document body was unreadable, limiting further analysis of the specific lure. The primary attack pattern observed is the mass distribution of external links.

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.
