SBN Details on the Unlocking of the San Bernardino Terrorist’s iPhone

The Washington Post has published a long story on the unlocking of the San Bernardino Terrorist’s iPhone 5C in 2016. We all thought it was an Israeli company called Cellebrite. It was actually an Australian company called Azimuth Security.

Azimuth specialized in finding significant vulnerabilities. Dowd, a former IBM X-Force researcher whom one peer called “the Mozart of exploit design,” had found one in open-source code from Mozilla that Apple used to permit accessories to be plugged into an iPhone’s lightning port, according to the person.

[…]

Using the flaw Dowd found, Wang, based in Portland, Ore., created an exploit that enabled initial access to the phone ­ a foot in the door. Then he hitched it to another exploit that permitted greater maneuverability, according to the people. And then he linked that to a final exploit that another Azimuth researcher had already created for iPhones, giving him full control over the phone’s core processor ­ the brains of the device. From there, he wrote software that rapidly tried all combinations of the passcode, bypassing other features, such as the one that erased data after 10 incorrect tries.

Apple is suing various companies over this sort of thing. The article goes into the details.
