T1566.001 Spearphishing Attachment

This PDF document employs a lure of free game hacks and items to entice users to click on embedded links. The primary link, http://netcdn.tw/app/431946152/free-roblox-intros-game-hack, is identified as a redirector to potentially malicious content. While no scripts were explicitly extracted, the PDF structure and embedded URIs suggest an attempt to lead the user to a malicious website, likely for credential harvesting or further malware delivery.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9932

Heuristics 3

  • 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.
  • External URI info PDF_URI

  • Embedded URL info EMBEDDED_URL
