The cryptocurrency lending project Radiant Capital was hacked for the second time in under a year, this time for more than $50 million in the USDC stablecoin, wBNB, ETH, and other tokens. An attacker successfully gained access to three of eleven private keys controlling a multisignature wallet, which enabled them to upgrade the project's smart contracts in such a way as to drain funds.
This is the second Radiant Capital exploit this year, after a $4.5 million theft in January that was enabled by an unaddressed vulnerability in the underlying Compound Finance code.
