GMX Exploit: $42M Hack & Token Plunge
One of the leading decentralized perpetual exchanges, GMX, experienced a significant security breach resulting in losses exceeding $42 million. This incident caused a sharp decline in the price of its native GMX token, as reported by PeckShield, a prominent blockchain security firm.
Key Findings
- Exploit Type: A re-entrancy vulnerability was exploited to abnormally mint GLP tokens, the platform's liquidity token.
- Losses: Over $42 million in cryptocurrency was stolen.
- Assets Stolen: The attacker's wallet currently holds over $32 million in Arbitrum and approximately $9.5 million in Ethereum.
- GMX Token Impact: The GMX token price dropped significantly, from $14 to $12, according to CoinGecko.
- GMX Response: While an official statement is pending, GMX has reached out to the attacker on-chain, offering a 10% bounty for the return of stolen funds.
Understanding the Re-entrancy Vulnerability
Re-entrancy attacks occur when a smart contract allows malicious code to repeatedly call a function within the contract itself, leading to unintended consequences like the over-minting of tokens observed in this case. This vulnerability underscores the critical importance of rigorous smart contract security audits.
