September 6th news, the decentralized exchange GMBL.COMPUTER in the Arbitrum ecosystem explained the process of today's signature key leak on the X platform: "Someone was able to forge a 'call' and obtain a signature from our server, then pass that signature to the contract and extract GMBL worth nearly 500 ETH (approximately $815,000 at current prices) from the contract."

GMBL.COMPUTER stated: "This is not a contract vulnerability. The root cause of the problem has been found and it occurred off-chain. We have obtained all their information and will start recovering funds. We offer a bug bounty and will not take legal action if the funds are returned."

The address that defrauded 1,155 wBTC has returned more than 96% of the funds to the victims

Blockchain data shows that the address poisoning attacker lured users to send 1,155 Wrapped Bitcoins (wBTC) (valued at $68 million at the time) to them. The attacker has returned almost all of the stolen funds. These funds were exchanged for Ethereum (ETH) during the attacker's holding period, and the price of ETH has since fallen. However, the attacker returned about 22,960.07 ETH, worth about $65.7 million, which accounts for over 96% of the initial stolen funds in terms of US dollar value.
