MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The primary link, http://netcdn.tw/app/479516143/minecraft-free-download-iphone-game-hack, is flagged as a redirector for game hacks. The document body and heuristics confirm the malicious intent of directing users to potentially harmful websites.

Machine Learning

  • Nyx PDF Classifier malicious score 0.9984

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.
