Over $1.7m was stolen from users of Concentric, a DeFi protocol on Arbitrum. The attackers were able to gain access to the protocol's admin keys, which they used to execute malicious upgrades on the protocol's contracts - allowing them to drain the wallets of any users that had active token approvals for the protocol.

Affected users remain at risk as long as they haven't revoked their approvals, so it is recommended to use the Exploit Checker below to make sure that you're safe.
