Moonwell, a lending protocol in the Base ecosystem, is suspected of being exploited after an attacker allegedly manipulated the MAMO collateral price and borrowed cbBTC from the mBTC market. Blockaid monitoring detected that about 50.6 cbBTC, worth more than $4 million, has so far been transferred out. The incident was reported on August 27. No further details on the attacker or protocol response were included in the source report.
