Concentric Hack

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.

受影响的用户只要没有撤销他们的授权，就仍处于危险之中。因此我们建议您使用Revoke.cash漏洞检查器，以确保资金安全。
