CERT Tapioca is a network-layer man-in-the-middle (MITM) proxy framework based on mitmproxy. CERT Tapioca is installable on Red Hat Enterprise Linux, CentOS, Fedora, Ubuntu, OpenSUSE, and Raspbian.The primary modes of operation are

  1. Checking for apps that fail to validate certificates – Simply associate device to access point or connect to network and perform the activity. Any logged https traffic is from software that fails to check for a valid SSL chain.
  2. Investigating traffic of any http/https traffic – Install the root CA of the MITM software that you are using into the OS of the device that you are testing.
