MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links pointing to external PDF documents hosted on the domain 'loaminoo.linkpc.net'. This behavior is indicative of a link farm or a redirection scheme, likely intended to drive traffic or potentially serve malicious content through these links. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact nature of the lure beyond the link farm. The primary technique observed is the use of external links to distribute or redirect users.

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.
