Burglars can block Nest – security cameras

Nest Dropcam, Dropcam Pro, Nest Cam Indoor (for indoor use) and Nest Cam Outdoor (for outdoor use) security cameras can be easily disabled by an attacker in the Bluetooth range of devices. The vulnerabilities are present in the latest version of the device firmware (5.2.1), identified by researcher Jason Doyle last fall, made known to Google but still not resolved.

Two vulnerabilities can be activated in such a way as to cause a buffer overflow condition if the attacker sends a parameter relating to the SSID to the cameras or specifies a password with a very long name: these systems allow the device to crash and cause the restart.

The third, more serious fault, allows an attacker to force the camera to temporarily disconnect from the wireless network to which it is connected, indicating an alternative SSID to connect to. If the SSID does not exist, the camera cancels the attempts and returns to connect with the previous Wi-Fi network, but this makes you lose 60 to 90 seconds, the time during which nothing is recorded. Nest says it has fixed the reported vulnerabilities but has not yet released the updated firmware.
