A Department of Justice investigation has concluded that the FBI inadvertently misled Congress when it said that it had exhausted all attempts to access the iPhone used by one of the San Bernardino killers.

The FBI claimed in a court filing that it had no means to access data stored on the iPhone without Apple’s assistance, a claim later repeated to Congress. A report covering this statement concludes that while it was technically true, it gave a misleading impression …

The report has the rather unwieldy title Accuracy of FBI Statements Concerning its Capabilities to Exploit an iPhone Seized During the San Bernardino Terror Attack Investigation. It addresses a statement made by then-FBI Director James Comey to Congress.

Noting that the FBI quickly succeeded in accessing the phone without Apple’s help, this was explained by the agency as a new technological development.

The report says that the FBI’s Remote Operations Unit (ROU) was in fact aware that a vendor was likely to be able to crack the phone.

On April 19, 2016, then-FBI Executive Assistant Director (EAD) Amy Hess testified about the matter before Congress and cited rapidly changing technology as a reason.

The report concludes that both Comey and Hess gave honest testimony to the best of their knowledge, but that inadequate communication within the agency lead to Congress being misled.

So although technically true that the FBI did not have the capability at the time of Comey’s statement, others in the agency were aware that the capability was likely to exist within a short time without Apple’s assistance.

The FBI succeeded in accessing the data through an undisclosed third-party vendor (which may or may not have been Cellebrite) and withdrew legal proceedings compelling Apple’s assistance. The agency later said that nothing significant was found on the phone.
