The Antbleed Backdoor
Antbleed is a backdoor introduced by Bitmain into the firmware of their bitcoin mining hardware Antminer.
The firmware checks-in with a central service randomly every 1 to 11 minutes. Each check-in transmits the Antminer serial number, MAC address and IP address. Bitmain can use this check-in data to cross check against customer sales and delivery records making it personally identifiable. The remote service can then return "false" which will stop the miner from mining. www.antbleed.com

Antbleed 2.0 *Confirmed
The procedure doing the second HTTP request is named isAuthToRun, so this seems to be similar to the "antbleed" functions, though this is in a different binary. It appears to make the call to bitmain.com with details of the hash boards and the MAC address, and returns a yes or no if the device is allowed to mine or not.
It's illegal to transmit personally identifying information without consent & breaks multiple international laws, especially exporting data out of the US & EU to non Safe Harbours.
