DForce hacker returns $25m in ‘stolen’ crypto-currencies
A mysterious hacker allegedly stole $ 25 million (£ 20 million) in cryptocurrencies – and then returned the funds two days later.
Records show that funds in a variety of cryptocurrencies were withdrawn from the China-based DForce platform.
A sum of $ 10 million was taken to Ethereum, for example, while another $ 10 million was withdrawn in digital currencies linked to the US dollar and $ 4 million in other currencies.
Roughly the same amount has now been returned, albeit in a different mix of cryptocurrencies.
DForce is an online service that allows users to carry out cryptocurrency transactions with each other.
“Hackers have tried to contact us and we intend to start discussions with them,” wrote Mindao Yang, founder of DForce in a blog shortly after the attack, on Sunday.
“This attack has damaged not only our users, our partners and my co-founders, but also me personally. My assets have also been stolen in this attack,” he added.
Yang promised a further update on the situation later today. The BBC also contacted DForce for comment.
In a technical blog about the alleged hackblockchain security firm PeckShield explained how the attacker managed to withdraw the cryptocurrency by tricking the DForce system.
In essence, the attacker would have been able to withdraw funds by convincing the system that the money had been deposited when it had actually been stolen.
