MITRE ATT&CK
T1566.001 Spearphishing Attachment T1566.002 Spearphishing Link

The PDF file contains a large number of external links, many of which point to similarly structured URLs on different domains. This indicates a link farm or SEO spamming technique. The primary heuristic identified a PDF URI pointing to 'completeimage.net' and a critical heuristic flagged a mass external PDF link farm hosted on 'kevintindell.com'. The document body contains garbled text but includes the phrase 'Illinois lottery pick 3 midday numbers', suggesting a lure. No scripts were extracted from this sample.

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.
