Bitmain is the biggest mining equipment seller in the world. They produce the famous Antiminers which are the best miners on the market. They are also owning top mining pools for Bitcoin and Litecoin.
They are the ones who currently can decide what forks and what doesnt, due to all the mining power on both chains.
Today it was found out that in firmware from July 2016+ there is a backdoor which was called AntBleed by its finders.
Long story short - by using this API calls they can possibly disable some miners they dont want to be running (ie voting for different blocksize outcome than they want) or fully identify users and their IPs and MAC adresses.
To disable this all you have to do is edit host file for: 127.0.0.1 auth.minerlink.com so there is no callback to home on the checker.
The pastebin of backdoor code is here https://pastebin.com/jREuwQ8b so you can have a deeper look on how it works.
