Foresight News reports that the GMX hacker has left a message on-chain stating that the funds will be returned. "ok, funds will be returned later."

According to previous Foresight News coverage, GMX disclosed the cause and subsequent measures regarding the approximately $40 million attack on GMX V1 on the Arbitrum chain on July 9. After analysis by the security team, it was determined that the attack stemmed from a reentrancy vulnerability in the OrderBook contract. The hacker exploited this vulnerability to manipulate the average price of BTC short positions, significantly driving up the price of GLP and profiting from the arbitrage.
