a little bit about this: researchers accessed the lidar information stored on robotic vacuums (like roomba) to extract audio data such as numbers, music, the sound of carpets etc.
The vacuum had to be previously compromised
The researchers had to be on the same network as the device.
Researchers gained root access to the device by exploiting an issue in the endpoint server of the device. While the information gained from the vacuum was fairly limited, and the requirements of the device being previously compromised, and being on the same network are limiting in the actual application of the exploit, researchers also think that a similar method could be used on smart phones.
regardless, it’s an important reminder to be especially mindful of security, especially as more of our devices are “smart” and present new avenues of exploitation.
