MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to external PDF documents, characteristic of a link farm. The heuristic PDF_SEO_LINK_FARM indicates a mass of external links, with the dominant host being loaminoo.linkpc.net. While the extracted URLs themselves are marked as benign, the sheer volume and structure suggest an attempt to manipulate search engine results or drive traffic to potentially malicious content hosted elsewhere. No scripts were extracted, limiting the ability to determine further malicious 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.
