1 ETH private key published during Blockd tool proof of concept, hacker unable to claim coins

Must hand it to the guy, he put his money where his mouth is. By the looks of it, the service watches the mempool for transactions involving the exposed address, and broadcasts a pre-signed transaction with a higher fee that knocks the first transaction out of the mempool. It appears that you pre-sign the same transaction several times, each time with progressively higher fees.

Great idea!
