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

The PDF file contains a heuristic firing for a link farm, indicating a large number of embedded URLs. These URLs point to external PDF files hosted on the same domain, suggesting an attempt to manipulate search engine results or distribute further malicious content. No scripts were extracted, and the document body was not fully readable, limiting further analysis of the specific lure. The primary attack pattern observed is the mass distribution of 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.
