Credit to Bruce Schneier: Vulnerability in Amazon Key - Schneier on Security Vulnerability in Amazon Key Amazon Key is an IoT door lock that can enable one-time access codes for delivery people. To further secure that system, Amazon sells Cloud Cam, a camera that watches the door to ensure that delivery people don't abuse their one-time access privilege. Cloud Cam has been hacked: But now security researchers have demonstrated that with a simple program run from any computer in Wi-Fi range, that camera can be not only disabled but frozen. A viewer watching its live or recorded stream sees only a closed door, even as their actual door is opened and someone slips inside. That attack would potentially enable rogue delivery people to stealthily steal from Amazon customers, or otherwise invade their inner sanctum. And while the threat of a camera-hacking courier seems an unlikely way for your house to be burgled, the researchers argue it potentially strips away a key safeguard in Amazon's security system.Amazon is patching the system.
