The Washington Post reports that the FBI paid hackers a flat fee to crack an iPhone 5c. The bureau reportedly used a zero-day flaw to crack the phone’s four-digit ID number without triggering a security feature that would have erased all the data. “I’m not believing a word of this until I see proof,” says security expert Dan Guido, CEO of security research and incident response firm Trail of Bits. The FBI declined to comment on the Washington Post report in particular, although one red flag with the report is that Cellebrite does sell a standalone phone-to-phone memory transfer and backup machine that matches the description of the hardware that was reportedly used by the FBI.”]
