MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The document displays a fake CAPTCHA or human verification prompt, a common lure to trick users into clicking malicious links. The embedded URI points to a URL associated with game hacks, further supporting a phishing or scamming attempt. No scripts were extracted, but the presence of multiple malicious URLs suggests the document is designed to lead the user to a site that likely hosts a second-stage payload.

  • Nyx PDF Classifier malicious score 0.8594

Heuristics 5

  • 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
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
  • 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.
