MITRE ATT&CK
T1566.001 Spearphishing Attachment

The primary URL, http://netcdn.co/app/431946152/free-gift-card-roblox-giverway-game-hack, is flagged as a lure for game hacks. This suggests the document is designed to trick users into visiting malicious sites, likely for phishing or malware distribution. No scripts were extracted, but the embedded URLs are the primary indicators of malicious intent.

  • Nyx PDF Classifier malicious score 0.9989

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
