Turkish hacker ‘Ibrahim Balic’ claimed responsibility for the Google Play Store attack. He found a flaw in the Android operating system while working with Android tools i.e. Compiler, debugger on his Emulators, that was crashing again and again. Then he created an Android app to exploit the vulnerability, ‘and uploaded it to the Google’s Developer Console’ The first crashed around Sunday and the same happened again on Monday when he tried a second time, leaving Android users unable to download new apps and games, and developers unable to update their own apps.
