MITRE ATT&CK
T1204 Malicious Link T1566 Phishing

The PDF contains a fake CAPTCHA heuristic, indicating a social engineering attempt to trick the user into interacting with the document. It also contains a large number of external links, many pointing to other PDF files, suggesting a link farm or redirection mechanism. The primary URL http://leadgenlogix.net/uploads/1/3/0/2/130288753/130288753.html#swansoft+cnc+simulator+latest+version appears to be the initial lure.

Heuristics 4

  • 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.
  • Fake CAPTCHA / human verification prompt high SE_FAKE_CAPTCHA
    Document displays a fake CAPTCHA or human-verification prompt — used to trick users into running commands or pressing keyboard shortcuts
  • 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.
