Cream Protocol Suffers Hack
Cream protocol, a defi lending-borrowing platform current on 4 totally different chains (Ethereum, BSC, Polygon, and Fantom), suffered a hack Monday that resulted in the lack of $29 million in a number of cryptocurrencies. The attacker took benefit of a bug brought on by the introduction of the amp token into the protocol. In accordance with Peckshield, a blockchain safety and knowledge analytics firm, the hack was perpetrated in only one transaction, benefiting from a reentrancy bug current in the code of the amp foreign money.
This allowed the hacker to re-borrow property through the switch earlier than updating the primary borrow. The exploit was repeated 17 instances and allowed the hacker to get ahold of 418,311,571 amp (value $25.1 million) and 1,308.09 ethereum (value $4.15 million).
