Security experts have discovered a new threat taking aim at Android phones with millions of users now being encouraged to check their devices immediately.
The latest attack, which was spotted by the team at McAfee Mobile Security, is able to infect popular applications with a malicious software library and begin performing tasks without the smartphone owners' consent.
Once a contaminated app has been installed, it can be used by criminals to see Wi-Fi history, what Bluetooth devices are connected to a phone, which apps are being used and even look at nearby GPS locations. That means a crook could know exactly where you've been.
