MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links, all pointing to the same domain 'cefasfese.4pu.com'. This technique is often used to distribute malicious content or to engage in SEO poisoning to drive traffic to malicious sites. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external PDF link farm, suggesting a deceptive lure. 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.
