This PDF document employs a fake CAPTCHA lure to trick users into downloading potentially malicious content from external URLs. The document body and extracted URLs suggest a theme of game hacks and cheats, aiming to exploit user interest. While no scripts were directly extracted, the presence of external URLs and the fake CAPTCHA heuristic strongly indicate an attempt to deliver a second-stage payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9432

Heuristics 4

  • 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
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
