Apple fixes HomeKit bug that left users' doors open to hackers

Apple has fixed a vulnerability in its HomeKit internet-of-things platform that allowed a hacker to take remote control of users' gadgets, including smart locks. 

9to5Mac first wrote about the vulnerability, which it says is "difficult to reproduce." Still, it was dangerous. If there was one iPhone or iPad running iOS 11.2 connected to a HomeKit user's iCloud account, that account was vulnerable. An attacker could potentially tamper with a user's smart lights or thermostats, or — even worse — open their garage or even their front door if it had a HomeKit-enabled smart lock.
