goTenna Pro ATAK Plugin Observable Response Discrepancy
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.
goTenna recommends that users mitigate these vulnerabilities by performing the following updates:
* ATAK Plugin: v2.0.7 or greater
Configurations
Workarounds
goTenna recommends that users follow these mitigations:
General Mitigations for All Users/Clients
* Use Discreet Callsigns and Key Names: Choose callsigns and key names
that do not disclose sensitive information, such as your location, team
size, or team name. Avoid using any identifiers that could
inadvertently reveal your location or the composition of your team.
* Secure End-User Devices: Implement strong security measures on all
end-user devices, including the use of encryption and ensuring regular
software updates.
* Follow Key Rotation Best Practices: Regularly rotate encryption keys
according to industry best practices to maintain ongoing security.
Pro-Specific Mitigations
* Share Encryption Keys via QR Code: Utilize QR codes, similar to ATAK, for the secure exchange of encryption keys.
* Secure Broadcasting: When broadcasting, ensure you are in a secured
area and transmit the key at a reduced power of 0.5 Watts to limit
exposure.
* Leverage Layered Encryption: Implement layered encryption keys to
securely manage communications, whether interacting with individuals or
teams.
