MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a significant number of embedded URLs, identified by the PDF_SEO_LINK_FARM heuristic. These URLs point to various book titles hosted on the 'loaminoo.linkpc.net' domain. While the URLs themselves are marked as confirmed benign, the sheer volume and structure suggest a link farm or SEO manipulation tactic, which can be a precursor to malicious activity. No scripts were extracted, and the document body was heavily corrupted, limiting further analysis of the specific intent.

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.
