T1566.001 Spearphishing Attachment

The PDF document employs a lure of game hacks and free in-game currency to entice users to click on embedded links. The primary link, http://netcdn.tw/app/431946152/how-to-hack-roblox-2021-game-hack, is identified as a redirector, suggesting it leads to further malicious sites or scams. No scripts were extracted, but the PDF structure and embedded URIs indicate a social engineering tactic to drive traffic to potentially harmful external resources.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9206

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
    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.
