In the goTenna Pro ATAK Plugin application, the encryption keys are stored along with a static IV on the device. This allows for complete decryption of keys stored on the device. This allows an attacker to decrypt all encrypted broadcast communications based on broadcast keys stored on the device.

The goTenna Pro ATAK Plugin does not inject extra characters into broadcasted frames to obfuscate the length of messages. This makes it possible to tell the length of the payload regardless of the encryption used.
