http://gigaom.com/2014/08/08/bitcoin-scammer-hijacked-chunks-of-traffic-from-amazon-and-others-researchers-claim/Dell SecureWorks security researchers have described a series of attacks earlier this year in which someone cleverly got miners of bitcoins and other “cryptocurrencies” like dogecoin to contribute their efforts to his mining pools, sending the proceeds to him instead of them.
Bitcoin mining involves solving complex computational problems faster than rivals, in order to add blocks of bitcoin transactions to the “blockchain,” the shared bitcoin ledger. Not only does this keep the blockchain going, but it also generates new bitcoins as rewards for the miners. Obviously, getting there first requires a lot of raw computational power, so most miners pool their resources.
