Hacker returns stolen funds from $40M GMX exploit

The attacker behind the $40 million GMX exploit has begun returning the stolen crypto after accepting a $5 million white hat bounty offered by the GMX team.

The attacker who exploited the GMX v1 decentralized exchange (DEX) and stole $40 million in crypto began returning the stolen funds after sending an onchain message promising to return the crypto. 

In an onchain message flagged by blockchain security firm PeckShield, the hacker wrote that the funds will be returned. “Ok, funds will be returned later,” the exploiter wrote in an onchain message, accepting the bounty offered by the GMX team. 

Almost an hour later, the hacker started returning the crypto stolen from the attack. At the time of writing, the address labeled GMX Exploiter 2 had returned about $9 million in Ether (ETH) to the Ethereum address specified by the GMX team in an onchain message.
