MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF contains a high-confidence heuristic indicating it links to a game hack lure, specifically targeting Roblox players. The embedded URL, https://netcdn.xyz/app/431946152/roblox-hack-ghost-game-hack, is the primary indicator of this lure. While no scripts were explicitly extracted, the nature of such lures often involves JavaScript to redirect users to malicious sites or initiate downloads. The document is therefore classified as a likely phishing attempt via attachment, aiming to trick users into visiting a potentially harmful website.

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
