Blackberry one of the hottest gadget used by corporate. A booby-trapped game of noughts and crosses has been used to show how a Blackberry can be hijacked to steal confidential data
According to BBC news, “Created by a security researcher the game contains malicious code that turns the popular mobile e-mail device into a backdoor into corporate networks.”
That is why you should never-ever install any games or other fancy stuff such as screen savers. Only way to prevent such a nasty stuff is to educate yourself. :)
