[Hexens Discloses Aptos Vulnerability Fixed, Potentially Impacting Cross-Chain Bridges and Stablecoin Infrastructure] According to a report by Jinse Finance, on July 5, blockchain security company Hexens disclosed that it had discovered a critical vulnerability in the Aptos blockchain's Move Virtual Machine (Move VM) back in February of this year. The issue was resolved within hours of reporting, with no financial losses incurred. Hexens stated that the vulnerability stemmed from a cache handling defect, which could lead to a type confusion exploit. In theory, attackers could leverage this to gain high-privilege roles in stablecoin minting, cross-chain bridges, and DeFi protocols. The research team used a server costing approximately $3,000 to set up a simulation environment close to the mainnet, conducting around 20 tests on the exploit path, with a success rate of 17 to 18 times. They assessed that the vulnerability could potentially impact approximately $250 million of Aptos's native Total Value Locked (TVL). If it were to further affect cross-chain bridges, stablecoins, and centralized exchanges, the theoretical systemic risk exposure could reach up to $70 billion. Aptos stated that the exploitability of the vulnerability in a real-world environment was extremely low and confirmed that it had been promptly fixed through its bug bounty program, with no impact on any users or funds.
