Security enthusiast Hemanth Joseph claims to have found that his Pebble Smartwatch with the latest v2.4.1 Firmware can be remotely exploited by anyone with no technical knowledge in order to delete all data stored in the device, apps, notes, and other information stored in it. Pebble, a wristwatch that can connect to your phone – both iOS and Android – and interact with apps, has a hard-coded vulnerability that allows a remote attacker to destroy your Smartwatch completely. When Pebble is connected to an Android or iOS phone, it will give a Vibrating alert to every messages from Whatsapp or Facebook with the whole message displayed on its screen.
