MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. These links all point to the same domain, loaminoo.linkpc.net, and appear to be part of a link farm designed to lure users to potentially malicious content. No scripts were extracted from this sample. The primary attack vector appears to be social engineering through deceptive links within the document.

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.
