A hacker stole $42 million in a GMX hack by exploiting GMX's GLP pool and conducting complex token swaps and cross-chain transactions to conceal the stolen funds.
GMX tried to negotiate with the hacker on-chain, offering to return 90% of the funds and keep 10% as a 'white-hat' reward, equivalent to around $4.2 million.
Despite the negotiation attempt, the hacker has not responded, and the address associated with the breach still holds close to $44 million in stolen funds.
The incident has raised concerns about protocol-level security in decentralized finance, prompting GMX to conduct a post-mortem analysis on the breach.
