Not a good day for xToken and DeFi investers, and its not the first time a hacker steals money from Defi protocols... so be carefull where you are puting your money.
The attack happened the day this article is being written, 12-mai-2021.The attacker used two exploits to steal the tokens.They used the flash-loan to borrow 61800 ETH, and this manipulated Kyber Network’s oracle, minting xSNXa tokens and fast traded it for ETH and SNX (Synthetix). Also, xBNTa contrat had a weakness explot, beeing possible to mint xBNTa tokens using any other tokens (not only BNT tokens, how it was suposed to word).
