MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF document contains multiple embedded URLs that redirect to a known malicious infrastructure, disguised as game hacks and free item generators. The primary lure URL is http://netcdn.tw/app/431946152/free-shirt-roblox-game-hack, which is likely intended to trick users into downloading malware or visiting a phishing site. No scripts were extracted, but the document's structure and embedded links strongly suggest a social engineering attack.

Heuristics 3

PDF links to a 'free generator / game hack' redirector critical 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. CRITICAL on its own: the /app/<id>/<slug>-game-hack path shape is unambiguous scam infra, and the host rotates so a host-list match can't be relied on.
PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK

PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
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.
