We have identified the issue & have paused the affected contracts.

“Urgent. Socket has experienced a security incident which affected wallets with infinite approvals to Socket contracts,” the post stated. “We have identified the issue & have paused the affected contracts.”
Socket is a cross-chain infrastructure protocol used by many Web3 apps, including Synthetix, Lyra, Kwenta, Superform, Plasma Finance and Level Finance.
Blockchain analyst Spreekaway reported the incident from their X account. According to them, the attacker used a token approval from an Ethereum address ending in 97a5 to carry out the exploit. Spreekaway recommended that users revoke all approvals from this address, which they claim shows up as “Socket: Gateway” on Etherscan. Socket claimed that it paused contracts and that “users don’t need to do ANYTHING.”

Phishing scammers appear to be taking advantage of the chaos to get new victims. In a reply to Socket’s official post, a fake Socket account posted a link to a malicious app and urged users to revoke their approvals using another malicious app that was also provided. The fake account contained the misspelled X handle @SocketDctTech instead of the correctly spelled @SocketDocTech. The fake account was removed from X within minutes of the post.
Dune Analytics user Beetle has set up a dashboard to track all losses from the attack.
