The goTenna Pro ATAK plugin uses a weak password for sharing encryption keys via the key broadcast method. If the broadcasted encryption key is captured over RF, and password is cracked via brute force attack, it is possible to decrypt it and use it to decrypt all future and past messages sent via encrypted broadcast with that particular key. This only applies when the key is broadcasted over RF. This is an optional feature, so it is advised to use local QR encryption key sharing for additional security on this and previous versions.

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.
