FBI is said to have received help from professional hackers to unlock the San Bernardino phone
According to The Washington Post, the FBI managed to unlock the phone belonging to one of the San Bernardino terrorists with the help of professional hackers who have identified one software vulnerability in the iPhone. This vulnerability is said to have been used for the creation of a software that allowed the FBI to break the pass-code protecting the phone, despite the inherent security features (that would have led to the data being erased if the wrong code had been entered 10 times).
