MITRE ATT&CK
T1204 Malicious Link T1204.001 Malicious Link: User Execution

The PDF document contains a large number of external links, a technique often used for SEO manipulation or to redirect users to malicious sites. The 'Fake CAPTCHA' heuristic indicates the document's intent is to deceive the user into clicking these links, likely for phishing or malware distribution. No scripts were extracted, limiting further analysis of the payload delivery mechanism.

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.
