ALERT! Our system detected a suspicious transaction targeting @futureswapx’s contract on #Arbitrum a few hours ago, resulting in an estimated loss of ~$395K. We have attempted to contact the team, but have not received a response so far. The attacker appears to have drained funds through multiple changePosition operations, eventually withdrawing a large amount of USDC. Since the contract is not open-sourced, the exact root cause still requires further investigation. Based on on-chain behavior, we suspect the incident may be related to unexpected stableBalance accounting changes during earlier position updates, which later allowed USDC to be released when removing collateral.
