Golden Finance reported that according to Arkham data, Radiant Capital was suspected of being hacked, and the attack initially occurred on Arbitrum and then transferred to BNB Chain. According to security company Ancilia, Radiant Capital suffered a hacker attack on its Arbitrum instance and BNB Chain, losing about $51 million. The attacker's wallet currently holds more than $32 million in Arbitrum assets and about $18 million in BNB Chain tokens. Tony Ke of security company Fuzzland said the attack originated from a vulnerability in the smart contract and may involve internal leaks. Users are advised to revoke all relevant contract authorizations immediately. Radiant lost about 1,900 ETH in a flash loan attack earlier this year.
