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

The document presents itself as a "hack" for a popular game, likely to trick users into clicking malicious links or downloading further payloads. The presence of a fake CAPTCHA heuristic strongly suggests a social engineering tactic to bypass user caution. The embedded URLs point to external resources that likely host the malicious content.

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

  • 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.
