MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to external PDF documents hosted on the loaminoo.linkpc.net domain. This suggests a link farm or redirection scheme designed to drive traffic to potentially malicious content. No scripts were extracted, and the document body was unreadable, limiting further analysis of the immediate payload. The primary attack pattern observed is the mass distribution of external links.

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.
