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

The document employs a fake CAPTCHA lure to entice users into clicking a malicious link, which is a common social engineering tactic. The embedded URLs, such as 'https://netcdn.xyz/app/479516143/toolbox-for-minecraft-pe-game-hack', likely lead to the download of a second-stage payload. While no scripts were explicitly extracted, the PDF structure and heuristics suggest an attempt to exploit user interaction for malicious purposes.

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.
