🥷🏻 Hacker returned part of the stolen $43 million from GMX
Earlier this week, a hacker stole over $43 million from the decentralized derivatives exchange GMX. After the incident, GMX reached out to him, offering 10% of the stolen amount in exchange for the return of the remaining funds without legal consequences.
According to PeckShield, the hacker responded that the funds would be returned later and made two transactions totaling 10.5 million FRAX to GMX's address.
The GMX team confirmed in a postmortem that the incident occurred due to a reentrancy bug that allowed the average price of shorts on BTC to be altered, raising the price of the GLP token and extracting profits.
