The popular French white hat hacker Robert Baptiste (aka @fs0c131y) discovered how to brick all Samsung mobile phones. Baptiste bought a Samsung mobile phone a few months ago and decided to analyze it. After a few hours of tests, he discovered an unprotected receiver in the ContainerAgent application. He also noticed that once opened the app for the 1st time, the app icon will disappear. Baptiste was able to create the final intent to lock the Knox container. The Samsung Security Team considered this issue as no/little security impact.”]
