ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

1. Go to your computers/phones settings
2. Ensure Bluetooth is turned on

How to exploit vulnerable implementations

• Doesn't validate signature? → Forge arbitrary JWTs
• Acts on data in payload before validating signature? → Forge arbitrary JWTs
• Doesn't validate signature algorithm? → Forge JWT with algorithm "none"
• Doesn't validate key↔algorithm match? → Create HS256 signature signed with expected public key
• Doesn't validate audience? → Trick victim to sign in to evil app, then use creds to auth to vulnerable app as victim
• Doesn't validate issuer? → Use JWT for one tenant to authenticate to a different tenant
• Doesn't validate nonce? → Replay attack
• Doesn't validate nonce/state against original sent value? → CSRF
