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

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. These links predominantly point to external PDF files hosted on the 'cefasfese.4pu.com' domain. While the extracted URLs themselves are currently marked as benign, the sheer volume and nature of these links suggest a malicious intent, possibly for SEO poisoning or to redirect users to further malicious content. No scripts were extracted from this sample.

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.
