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

The PDF file contains a large number of external links, forming a link farm. The primary heuristic indicates this is a malicious SEO tactic, likely intended to drive traffic to potentially malicious content hosted on the dominant domain 'zsxfwqaa.4dq.com'. While the document body is heavily corrupted, the presence of numerous URLs suggests a social engineering attempt to direct users to external sites.

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.
