T1566.001 Spearphishing Attachment
The PDF document employs a common lure of 'free Robux' and game hacks to entice users to click on external links. The heuristic findings indicate a link farm strategy, with numerous PDFs hosted on external domains, suggesting a potential SEO manipulation or content distribution scheme. While no scripts were explicitly extracted, the PDF structure and embedded URLs point towards a malicious intent to redirect users to potentially harmful sites.
Machine Learning
- Nyx PDF Classifier malicious score 0.9724
Heuristics 5
-
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.
-
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 https://netcdn.tw/app/431946152/free-robux-hack-no-confusion-game-hack PDF link annotation
