Researchers say factory resetting an Amazon Echo Dot isn’t enough to protect your privacy.
Northeastern University researchers showed that factory resetting an Amazon Echo Dot isn’t enough to protect your personal information from someone with physical access to the device. The researchers said anyone with that physical access could « retrieve sensitive information such as Wi-Fi credentials, the physical location of (previous) owners, and cyber-physical devices (e.g., cameras, door locks) » from an Amazon Echo Dot even after it’s been factory reset. They also said these devices reveal that data as well as « all previous passwords and tokens » after a reset « due to the wear-leveling algorithms of the flash memory and lack of encryption.
