MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a large number of embedded links to external PDF files hosted on the domain 'loaminoo.linkpc.net'. This pattern is indicative of a link farm, likely intended for SEO manipulation or to distribute further malicious content. While no scripts were directly extracted, the PDF structure and embedded URLs suggest a potential for malicious redirection or content delivery, aligning with T1566.001 (Spearphishing Attachment) if this PDF was delivered via email. The ML classifier also flagged this PDF as malicious.

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.
