The primary link, http://netcdn.tw/app/479516143/when-was-minecraft-free-game-hack, redirects to a malicious website, likely to download further malware or conduct phishing. No scripts were extracted, but the document's structure and embedded URLs strongly indicate a malicious intent to trick users into visiting harmful sites.

Heuristics 4

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.
