MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs, identified as a 'PDF_SEO_LINK_FARM' heuristic. These URLs point to various book titles hosted on 'loaminoo.linkpc.net'. While the individual URLs are marked as benign, the sheer volume and the nature of the heuristic suggest a malicious intent to manipulate search engine results or distribute potentially unwanted 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.
