According to PShield monitoring, Radiant Capital, a multi-chain lending agreement, suffered a loss of 1,900 ETH (4.5 million US dollars) due to a hacker attack. The hacker basically took advantage of a time window when a new market in the lending market (derived from Compound/Aave) was activated. This vulnerability also depends on the rounding issue known in the current Compound/Aave codebase. Earlier today, Radiant Capital officials posted on X platform that the newly created native USDC market on Arbitrum had issues. After verification by Radiant developers and the wider Web3 security community, Radiant DAO has suspended the lending market on Arbitrum and is further investigating the issue. Currently, there is no risk to any funds.
