MITRE ATT&CK

T1566.001 Spearphishing Attachment

The PDF contains multiple heuristics indicating a lure for game hacks, specifically targeting Roblox. The primary URL, https://enigmagenerator.com/app/431946152/roblox-game-hack, is directly linked to a 'free generator / game hack' lure. The document body, though heavily corrupted, contains references to this URL and mentions 'wkhtmltopdf', suggesting it was generated by a tool rather than authored directly. The presence of numerous embedded URLs pointing to similar hack-related content reinforces the malicious intent.

Nyx PDF Classifier malicious score 0.6397

Heuristics 5

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.
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE

Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
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.
