MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded links pointing to external PDFs hosted on the domain 'cefasfese.4pu.com'. This technique is often used to distribute malicious content or to engage in SEO manipulation for phishing purposes. No scripts were extracted, and the document body was unreadable, limiting further analysis of the specific lure.

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.
