White hat hackers claim that the vulnerability that led to the $200 million theft from Euler was caused by fixing another vulnerability

ChainCatcher news reports that a white hat hacker named Kankodu claimed to have discovered Euler's "first deposit bug" in July 2022, for which he received a $50,000 bug bounty. However, the "donateToReserves" function introduced during the fix of this bug led to a subsequent theft of $200 million.

According to previous reports from ChainCatcher, Euler Finance suffered a hacker flash loan attack in March this year, with losses amounting to approximately $197 million, including 8,877,507.35 DAI, 849.14 WBTC, 34,413,863.42 USDC, and 85,818.26 stETH.
