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

The PDF document contains a large number of embedded URLs, as indicated by the PDF_SEO_LINK_FARM heuristic. These URLs point to external resources, suggesting a potential phishing or SEO manipulation attempt. No scripts were extracted from this sample. The primary attack pattern involves directing users to these external links, which are predominantly hosted on 'cefasfese.4pu.com'.

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.
