This PDF document contains numerous embedded links, many of which are presented as download opportunities for game cheats and hacks. The document body and heuristics indicate a strong intent to direct users to external URLs, such as http://netcdn.tw/app/431946152/roblox-cheat-dll-2021-game-hack, likely to facilitate the download of malicious payloads. The ML classifier also strongly flagged this PDF as malicious.

  • 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.
