Dumbo corrupts the enemy's audio/video surveillance
Dumbo is designed to automatically detect installed devices like webcams and microphones, either locally or connected by wireless (Bluetooth, WiFi) or wired networks. The tool lets operators disable these devices.
In addition, Dumbo also detects any processes related to these devices and the processes of recording or monitoring software. Agents can use the tool to delete or corrupt these processes, and indirectly their recordings.
The
latest manual is entitled Dumbo v3.0 and is dated June 25, 2015. According to the manual, Dumbo needs SYSTEM privileges in order to run. This implies that CIA agents must use dedicated exploits together with Dumbo in the case they don't have access to a SYSTEM-level account.
