MITRE ATT&CK
T1059.001 PowerShell

The PDF file contains a large number of embedded URLs pointing to external PDF documents hosted on the domain 'loaminoo.linkpc.net'. This is indicative of a link farm or a content distribution network for malicious files. The heuristic 'PDF_SEO_LINK_FARM' strongly suggests this malicious intent. No scripts were extracted from this sample, and the document body contained mostly garbled data with embedded URLs.

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.
