T1203 Exploitation for Client Execution
The PDF contains a launch action and multiple embedded URLs, including one that directly advertises a 'free robux' hack. The document body also contains similar lures and URLs, indicating a phishing or scam attempt. The presence of a PDF launch action suggests an attempt to exploit a vulnerability for client execution, likely to redirect the user to a malicious site.
Machine Learning
- Nyx PDF Classifier malicious score 0.9980
Heuristics 6
-
Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Launch action high PDF_LAUNCHPDF contains a /Launch action with an unresolved or extension-less target — treat as potentially dangerous
-
PDF links to a 'free generator / game hack' redirector high PDF_GAME_HACK_REDIRECT_LUREPDF'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_BUTTONDocument 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_URIPDF contains an external URL action
-
Embedded URL info EMBEDDED_URLOne 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.URL http://netcdn.tw/app/431946152/get-robux-for-free-2021-game-hack PDF link annotation
