MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a mass link farm pointing to numerous external PDF documents hosted on the domain 'muicuiu.dumb1.com'. This heuristic, combined with the ML classifier's high confidence, suggests a malicious intent to redirect users to potentially harmful content. No scripts were extracted, and the document body primarily consists of these links.

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.
