MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document contains multiple embedded URLs that are designed as lures for game hacks and free in-game currency. The primary URL, http://netcdn.tw/app/406889139/coin-master-free-spins-ios-2021-game-hack, strongly suggests a malicious intent to redirect users to potentially harmful content. The presence of a 'download button' heuristic further supports the idea that the document is intended to trick users into downloading a payload.

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
