The Justice Department has found a way to unlock Syed Rizwan Farook’s iPhone without help from Apple, but has not told the company how.

Earlier this year, the FBI expressed to Apple that they wanted them to unlock the iPhone of Farook — who was one of the gunmen involved in the San Bernardino shooting, in which 14 people were killed, according to officials. Apple denied to do so because it would have been an invasion of privacy for all iPhone users.

Because the law enforcement was able to unlock the iPhone without the help of Apple, it is in question now about how secure Apple’s devices truly are.

It isn’t certain yet if the way the government opened the iPhone will be made known, but Apple lawyers want to know.

“I would hope they would give that information to Apple so that it can patch any weakness,” Esha Bhandari, staff lawyer at the American Civil Liberties Union, said in a statement.

The device was unlocked without a password. It doesn’t seem like the government will spill the details on it anytime soon.

Since it is unlikely that the FBI will tell Apple how they got access to the phone, the company said they’ll “continue to increase the security of our products as the threats and attacks on our data become more frequent and more sophisticated,” in a statement.

There has been a lot of back and forth between Apple and the FBI regarding the situation with Apple not wanting to unlock the phone because it would have been an invasion of privacy for all Apple users and make it look like they’ll do it for any circumstance.

“Now that the F.B.I. has accessed this iPhone, it should disclose the method for doing so to Apple,” said a cryptography fellow at the Stanford Center for Internet and Society, Riana Pfefferkor, according to the New York Times. “Apple ought to have the chance to fix that security issue, which likely affects many other iPhones.”
