MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF contains a large number of embedded links, identified as a link farm. The primary heuristic indicates this is a critical finding, suggesting the document's purpose is to direct users to numerous external sites. No scripts were extracted from this sample. The domain 'cefasfese.4pu.com' is the dominant host for these links.

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.
