MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF document contains a heuristic firing for a 'PDF_SEO_LINK_FARM', indicating a large number of external links. The document body also contains numerous embedded URLs, many of which point to the same dominant host 'cefasfese.4pu.com'. This suggests the PDF is designed to lure users to click on these links, potentially leading to malicious content or further compromise.

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.
