VoIPShark: Open Source VoIP Analysis Platform

VoIPshark is an open source platform for VoIP analysis. It is created as a collection of Wireshark plugins. After installation, it will be available within Wireshark. This platform was created while working on “VoIP Traffic Analysis” course. Those interested can check the course here

VoIPShark will enable the user to do the following:

  1. Perform macro analysis on VoIP traffic
  2. Decrypt live or stored VoIP traffic while preserving packet structure and time information
  3. Export VoIP audio streams to popular media formats
  4. Detect the following threats/attacks

    • Message flood
    • Invite flood
    • SIP MiTM attack
    • Teardown
    • Enumeration
    • Attack tool detection
