FBI Director James Comey says the FBI is still studying the software vulnerability that allowed the agency, with third party help, to access a locked iPhone used by one of the San Bernardino, California attackers.

He told an audience at a Georgetown University conference Tuesday that “we’re really close to sorting that out.” He said that work will inform the decision of whether the government reveals the vulnerability to Apple Inc.

A still-unidentified third party approached the FBI last month with a method that it said could open the locked iPhone 5C of Syed Farook, who along with his wife killed 14 people in the December attacks.
