WASHINGTON DC – The FBI is maintaining its silence about a hack that gave it access to data on a terrorist’s iPhone, although earlier reports claimed an Israeli company masterminded the exploit.

As expected, the agency released a statement Wednesday, reported by CNET.Com, arguing that it doesn’t know enough about the hacking method to submit it for an Obama administration review. The bureau worked with a third party to hack into the device. The review, known as the Vulnerabilities Equities Process, would determine whether the method should be shared with Apple and the public.

“The FBI assesses that it cannot submit the method to the VEP,” an FBI spokeswoman said in a statement. “We do not have enough technical information about any vulnerability that would permit any meaningful review.”

The FBI spent over $1.3 million to unlock the iPhone of San Bernardino shooter Syed Farook, and reportedly found nothing important inside. Apple, which took a high-profile stand against an FBI demand that it hack into the device, wants to know if there’s a security weakness it could fix.

Earlier it was reported that Cellebrite, a privately held Israeli company that specializes in transferring or extracting data from phones, helped the FBI unlock the iPhone, according to a report in the Yedioth Ahronoth newspaper.
