MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document employs a common lure of 'game hacks' and 'free generators' to entice users into clicking embedded links. The primary link, http://netcdn.co/app/479516143/client-minecraft-game-hack, is associated with a redirector that likely leads to malicious content or phishing pages. The document's structure and embedded URLs suggest it is part of a broader campaign distributing malware or engaging in scams, potentially using social engineering tactics to trick users into downloading further payloads.

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.
