T1566.001 Spearphishing Attachment T1203 Exploitation for Client Execution

This PDF document employs a common lure of 'free Robux' and 'game hacks' to entice users to click on embedded links. The primary link, http://netcdn.tw/app/431946152/free-robux-roblox-promo-codes-game-hack, is highly suspicious and likely leads to a malicious website or a download of further malware. While no scripts were explicitly extracted, the PDF structure and embedded links suggest an attempt to exploit user interest in gaming to deliver a payload.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9980

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.
