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

The PDF document was identified as malicious due to a critical heuristic firing for a link farm. It contains numerous external URLs, with the primary ones being http://472-476thomas.com/uploads/1/3/0/8/130874282/130874282.html#corniche+kennedy+lecture+analytique and http://mail.cancer-ride-arctic-pacific-atlantic.kiwi.nz/uploads/1/3/0/5/130538859/fenolufalefanasekuw.pdf. These links likely serve as lures to download further malicious content or to phish users.

Heuristics 3

  • 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.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
