MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded links pointing to external PDF documents hosted on the domain 'loaminoo.linkpc.net'. This technique, identified by the PDF_SEO_LINK_FARM heuristic, is often used for SEO poisoning or to distribute malicious content. While the specific intent of the linked PDFs is unclear, the sheer volume and the suspicious domain suggest a malicious distribution or redirection scheme. 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.
