MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains embedded URLs that are designed to lure users into clicking on links related to game hacks and free in-game currency. The primary URL, http://netcdn.tw/app/406889139/200-free-spins-coin-master-game-hack, is flagged as a redirector for game hacks. This suggests the document's purpose is to trick users into visiting potentially malicious websites, likely for credential harvesting or malware distribution. No scripts were extracted, but the embedded URLs and the 'game hack' lure are strong indicators of a phishing or scam attempt.

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.
