A hacker posted a video on Twitter to show how to access a locked door after a delivery workers one-time code has been used. The hacker used a dropbox device that appears as tiny PC with Wi-Fi connectivity that is able to control the Amazon Key. A few days after the announcement, researchers with Rhino Security Labs demonstrated how to disable the camera on Amazon Key, which could let a rogue courier access the customers home. The technology seems to be totally secure, a hacker has in fact demonstrated another attack on the Amazan Key.”]
