T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

This PDF document exhibits characteristics of a phishing or malware distribution lure. It displays a fake CAPTCHA or human verification prompt, a common tactic to deceive users into interacting with malicious content. The presence of multiple embedded URLs, including one pointing to a potential exploit or download site, further supports this assessment. The document's content and structure suggest an attempt to trick users into downloading a payload or providing sensitive information.

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
  • MFA / one-time-code harvesting lure high SE_MFA_LURE
    Document asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
  • 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.
