MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

This PDF document contains a large number of embedded links to external PDF files hosted on the loaminoo.linkpc.net domain. The heuristic PDF_SEO_LINK_FARM indicates this is a link farm, suggesting a tactic to manipulate search engine results or drive traffic. While the document body is heavily corrupted, the presence of numerous links points to a content-luring or SEO poisoning attack pattern. No scripts were extracted from this sample.

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.
