Hacker Returns 225 BTC Taken from Blockchain Wallets

A white-hat hacker who was able to take 255 BTC from Blockchain wallets following a security flaw earlier this week claims to have returned the funds.
Bitcoin Talk member ‘johoe’, an account 1.5 years old but with only 21 posts, had always stated that he or she was taking the funds for safekeeping and would return them, writing on the forum:
“There were a large bunch of new broken addresses today (several 100s in one day). I took the liberty of saving some funds before they got swiped by others. If you can convince me that they belong to you (signing a message with the address is obviously not enough; the private key is already known), I will send the funds back.”
