It was recently reported that blockchain.info users had up to 250 bitcoins lost during a security lapse that took place during the early hours of Monday, December 8th. The site took full responsibility for the situation on Twitter, announcing that they were at fault and would work towards reimbursing any whose funds may have disappeared during the event.
Now, what can only be described as a “hacker with morals” has come forward to confess that he had taken (and has now returned) the lost bitcoins. Going by the name ‘johoe’ on the popular forum Bitcoin Talk, the hacker explains:
“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.”
Johoe then posted a list of over 1,000 addresses that he believed had been compromised and invited users to check if the list included theirs. Following email communication with blockchain CTO Ben Reeves, johoe later posted:
“The money has been returned to blockchain.info. Please write to blockchain support to claim refund.”
In response, johoe has received acclaim from the bitcoin community, with some even going so far as to suggest that blockchain compensate or hire him.
