MITRE ATT&CK

T1566.001 Spearphishing Attachment

This PDF document contains multiple links disguised as game hacks and free item generators, a common lure for phishing or malware distribution. The primary link, 'https://netcdn.xyz/app/406889139/coin-master-free-blogspot-game-hack', strongly suggests a malicious intent to redirect users to potentially harmful content. While no scripts were explicitly extracted, the PDF structure itself contains URI actions that facilitate this redirection, aligning with T1566.001 (Spearphishing Attachment) as the likely initial access vector.

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
External URI info PDF_URI

PDF contains an external URL action
Embedded URL info EMBEDDED_URL

One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
