What happened
On May 12, 2021, xToken was exploited when an attacker used an $81M flash loan (61,800 ETH) from dYdX to manipulate Kyber Network's oracle, enabling minting of xSNXa tokens at manipulated prices for ETH and SNX. The xBNTa contract had an additional flaw allowing minting with any token, not just BNT.
