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

The PDF file contains a heuristic firing for a link farm, indicating an attempt to direct users to numerous external websites. The embedded URLs, disguised as book titles, are the primary mechanism for this redirection. While the specific intent of these external sites is not clear from the provided evidence, the sheer volume and the nature of the heuristic suggest a malicious attempt to drive traffic or potentially host malicious content. No scripts were extracted from this sample.

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.
