GMX Hacker Returns Stolen Funds, Nets $3 Million Profit on ETH & Also Claiming Bounty

Main Idea

A hacker returned $10.49 million in stolen FRAX to GMX in exchange for a $5 million white-hat bounty, while profiting $3 million from swapped ETH, following a re-entrancy exploit on GMX's V1 protocol.

Key Points

1. The GMX hacker returned $10.49 million in FRAX and committed to returning the remaining $32 million in exchange for a $5 million bounty.

2. The hacker swapped the remaining stolen funds into 11,700 ETH, netting a $3 million profit due to price appreciation.

3. GMX paused GLP minting and redemption after the exploit and offered a 10% bounty with no legal action if funds were returned within 48 hours.

4. The exploit, traced to a re-entrancy vulnerability in the GLP pool, caused GMX's native token to drop roughly 20%.

5. Despite the hack, the broader crypto market remained unaffected, with Bitcoin and Ethereum rising by 2% and 6%, respectively.
