MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document employs a lure of free game hacks and generators, as indicated by the 'PDF_GAME_HACK_REDIRECT_LURE' heuristic and the document body content. It contains numerous embedded URLs, with http://netcdn.tw/app/479516143/free-minecraft-severs-game-hack being a primary example. These links likely lead to malicious websites designed to exploit users or deliver further malware. No scripts were extracted from this sample, but the overall pattern suggests a phishing or social engineering attack.

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.
