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

The PDF document contains a lure related to resetting a G-Shock watch, but its primary function is to act as a link farm. It hosts numerous external links, identified by the PDF_SEO_LINK_FARM heuristic, which point to other PDF files on various domains. These links are likely intended to distribute further malicious content or lead users to phishing sites.

Heuristics 3

  • 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.

    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
