You can hack iPhone 5c for less than $100 with NAND bypass

The FBI could have saved millions with this iPhone 5c hack

You may have already read about how FBI spent $1.3 million to hack into the locked iPhone 5c belonging to San Bernardino shooter. It seems FBI overspent money as the iPhone 5c can be hacked for as little as a $100 according to a security researcher, Sergei Skorobogatov from the University of Cambridge.

Skorobogatov used a technique called NAND mirroring to bypass the passcode-retry limit set by Apple on iPhone 5c.  Skorobogatov demonstrated the iPhone 5c hack using store-bought equipment for just $100. From the equipment, he created copies of the phone’s flash memory to generate more tries to guess the passcode.

Skorobogatov detailed the whole process in a new paper  and was able to gain entry into a locked iPhone 5c using the NAND mirroring technique.

Users may remember FBI had emphatically said in March that NAND mirroring technique can’t be used on Apple products, especially, iPhone 5c. “It doesn’t work,” FBI Director James Comey said back in March. To gain access the San Bernardino shooter’s iPhone 5c, the FBI instead resorted to reportedly paying an Israeli contractor around $1.3 million.

Apple’s iPhone 5c is passcode protected with a limiter for passcode tries and has an auto-erase function that would activate after 10 failed tries, deleting all the data inside.

Skorobogatov’s paper, published on Thursday, provides a working prototype on how to pull off the hack. The equipment he used consisted of off-the-shelf components, and his tests involved iPhone 5cs updated with the latest 9.3 version of iOS.
