MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple links that are designed to lure users into downloading game hacks or cheats. The primary link, 'https://netcdn.xyz/app/431946152/wall-hack-phantom-forces-roblox-game-hack', is flagged as a game hack redirector lure. While no scripts were explicitly extracted, the PDF structure and embedded URLs suggest an attempt to redirect users to malicious content, likely for credential harvesting or malware delivery.

Heuristics 3

  • PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LURE
    PDF's clickable action targets a redirector of the form /app/<id>/<slug>-game-hack — the landing-page shape of a large SEO 'free spins / generator / game hack' lure family that funnels victims through rotating disposable hosts to a malware/scam payload. The multi-link variants also trip ML/link-farm rules; this catches the single-link variants that otherwise score clean.
  • External URI info PDF_URI
    PDF contains an external URL action
  • Embedded URL info EMBEDDED_URL
