MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains multiple links and a lure related to "game hacks" and "free spins" for popular mobile games. The primary link, https://netcdn.xyz/app/406889139/app-for-free-spins-on-coin-master-game-hack, suggests a social engineering tactic to trick users into downloading potentially malicious software. While no scripts were explicitly extracted, the PDF structure and embedded URLs indicate a phishing or malware distribution attempt.

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.
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

PDF contains an external URL action
Embedded URL info EMBEDDED_URL
