The Antbleed Backdoor Antbleed is a backdoor introduced by Bitmain into the firmware of their bitcoin minerlink bitcoin 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. It can also be used to directly target specific machines or customers. Standard inbound firewall rules will not protect against this because the Antminer makes outbound connections. Even without Bitmain being malicious, the API is unauthenticated and would allow any MITM, DNS or domain hijack to shutdown Antminers globally. Additionally the domain in question DNS is hosted by Cloudflare making it trivially subjected to government orders and state control. All recent S9 hardware is affected, except possibly very early generation S9s. Additionally, L3, T9 and R4 series hardware are likely to be affected as well.

The commit date for the backdoor kill switch is July 11th, 2016, if your firmware claims to be after this date that is a good indication that your Bitmain hardware is affected. If your miner is vulnerable it will cease mining within 11 minutes, or you can reboot your miner and the connection will be made on startup. This will cause the Antminer to connect to your own local machine bypassing the check-in with Bitmain without interrupting normal mining behavior. Is This Just A User Feature? The domain and port are hard coded in the source files, theres no way to change them without recompling and loading new firmware. There is no way a user could make use of it in any realistic way. 4 Connect to Miner 6 Miner Configuration 8 Pool Setting 8 Frequency Modification .

9 System Configuration and status . It’s with several different hash rate and the final one is 4. S7 are tested and configured prior to shipping to make it easier for customers to set up. Page 4: Features Higher input voltage will cause higher mining efficiency. 15A DC STABLE input on hash boards and 1 PCI-e connector on the controller, all the 10 PCI-e connectors are required. Do not connect more than one PSU to the same hashing board to prevent possible damage and instability. 2016 Page 6 of 11 4 Connect to Miner Step 1.

The pools with low priority will only be used if all higher priority pools have gone offline. Keep setting’ is chosen by default and should be enabled if you want to keep your current settings. You should deselect this option if you are trying to return the miner to default settings. 2016 Page 11 of 11 7.
