The goTenna Pro ATAK Plugin does not use SecureRandom when generating passwords for sharing cryptographic keys. The random function in use makes it easier for attackers to brute force this password if the broadcasted encryption key is captured over RF. This only applies to the optional broadcast of an encryption key, so it is advised to share the key with local QR code for higher security operations.Show less

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.Show less

The goTenna Pro ATAK Plugin's default settings are to share Automatic Position, Location, and Information (PLI) updates every 60 seconds once the plugin is active and goTenna is connected. Users that are unaware of their settings and have not activated encryption before a mission may accidentally broadcast their location unencrypted. It is advised to verify PLI settings are the desired rate and activate encryption prior to mission. Update to the latest Plugin to disable this default setting.Show less

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.Show less

The goTenna Pro ATAK Plugin uses AES CTR type encryption for short, encrypted messages without any additional integrity checking mechanisms. This leaves messages malleable to an attacker that can access the message. It is advised to continue to use encryption in the plugin and update to the current release for enhanced encryption protocols.Show less

The goTenna Pro ATAK Plugin encryption key name is always sent unencrypted when the key is sent over RF through a broadcast message. It is advised to share the encryption key via local QR for higher security operations.Show less

In the goTenna Pro ATAK Plugin there is a vulnerability that makes it possible to inject any custom message with any GID and Callsign using a software defined radio in existing goTenna mesh networks. This vulnerability can be exploited if the device is being used in an unencrypted environment or if the cryptography has already been compromised. It is advised to use encryption shared with local QR code for higher security operations.Show less
