There's a crazy exploit sneaking around that could brick your Samsung phone and break into your physical memory to steal your data. But don't freak out; Samsung says it's aware of the problem and is working quickly on software fixes.
Samsung confirmed to Android Central suspicions that the problem is an Exynos processor vulnerability issue. What the exploit does is it gives a malicious app access to all of your RAM so that it could steal your info, wipe your phone, etc. So be sure to avoid any apps that seem sketchy because they might get you. If you were affected, there are already some third-party fixes available. Working on a fix is obviously a far cry from having one, but the hardest step is always admitting you have a problem.
