Dumbo also reports operators where footage files are stored allowing their corruption or deletion.
“[The tool] identifies installed devices like webcams and microphones, either locally or connected by wireless (Bluetooth, WiFi) or wired networks. All processes related to the detected devices (usually recording, monitoring or detection of video/audio/network streams) are also identified and can be stopped by the operator,” WikiLeaks said. “By deleting or manipulating recordings the operator is aided in creating fake or destroying actual evidence of the intrusion operation.”
