Apple’s next big encryption battle with the federal government appears to be unfolding in a largely secret court case in Massachusetts involving an FBI bust of a gang called the Columbia Point Dawgz.

Thursday, the American Civil Liberties Union filed a motion to unseal a list of documents in the case (embedded below), in which the government appears to be trying to use the controversial All Writs Act of 1789 to force Apple to help it decrypt what is believed to be an iPhone 6 Plus running iOS 9.1.

And:

All iPhones running iOS 8 or greater have device encryption enabled by default. But unlike the San Bernardino shooter’s iPhone 5c, the iPhone 6 and other newer iPhone models have a hardware security feature called Secure Enclave, which makes cracking the device’s passcode significantly harder. Ostensibly, that would once again put Apple in the hot seat as the only one capable of helping unlock the phone.

Keep your eye on this one.
