MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF document contains a large number of embedded links to external PDF files, all hosted on the domain 'cefasfese.4pu.com'. This behavior is indicative of a link farm or a phishing lure, aiming to direct users to potentially malicious content. No scripts were extracted, and the document body was heavily obfuscated, limiting further analysis of the specific lure. The primary IOCs are the URLs pointing to the external PDFs.

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.
