At the time of publication of the article, about 150,000 ETH were stolen, which is more than $ 30 million. This data is also confirmed by the Etherscan service.
As explained by the Parity team, the problem arose as a result of an error in a separate contract with a multiplier known as wallet.sol.
According to preliminary data, the potential consequences have already been mitigated, and another 377,000 ETH were protected from theft by attackers by WhiteHat's actions by hackers.
