T1059.001 PowerShell

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to external PDF files hosted on loaminoo.linkpc.net. While the ML classifier strongly indicates maliciousness, the specific intent beyond link farming is unclear as no scripts were extracted and the document body was unreadable. The numerous links suggest an attempt to drive traffic or potentially distribute further malicious content.

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.
