Seneca Hack

Over $6m was stolen from users of DeFi protocol Seneca on Ethereum and Arbitrum. Fortunately 80% of the stolen funds were returned while the attackers kept 20% as a bounty after an onchain message from Seneca. The Malicious actors used arbitrary calldata parameters to call transfers for approved user tokens, exploiting a vulnerability in Seneca's Chamber contract.

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