MITRE ATT&CK
T1566.001 Phishing: Spearphishing Attachment T1059.001 Command and Scripting Interpreter: PowerShell

The PDF file contains a heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a large number of embedded external links. The document body confirms the presence of numerous URLs, many of which are structured with numeric slugs and book titles, suggesting an attempt to manipulate search engine results or redirect users to potentially malicious content. No scripts were extracted from this sample. The primary attack pattern appears to be a link farm or SEO spam, potentially serving as a lure for further malicious activity.

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.
