Overview


This research focuses on understanding how modern antibot protection systems work, including their detection mechanisms and challenge systems.


Methodology


  • **Traffic Analysis**: Captured and analyzed network traffic to understand the communication patterns between client and protection server.

  • **JavaScript Analysis**: Deobfuscated and analyzed the client-side JavaScript code responsible for challenge solving and fingerprint collection.

  • **Fingerprint Vectors**: Identified and documented various fingerprinting techniques including:

    • - Canvas fingerprinting

    - WebGL renderer detection

    - Audio context analysis

    - Navigator/screen enumeration
