BarnBridge governance attack reportedly causes approximately $776,000 in losses
According to BlockSec monitoring, the BarnBridge SMART Yield cUSDC protocol was attacked on Ethereum, resulting in losses of approximately $776,000, suspected to be a governance attack. The attacker first gained DAO governance rights, then upgraded the SmartYield/controller proxy to a malicious implementation contract. This contract called the _takeUnderlying privileged function of CompoundProvider, utilizing pre-existing USDC approvals from 50 user accounts, and via transferFees, moved the aggregated funds to the attacker.
