Mars Finance News: According to BlockSec monitoring, a suspicious transaction occurred on the FutureSwapX contract on the Arbitrum chain, with an estimated loss of approximately $395,000. BlockSec stated that they have attempted to contact the team but have not yet received a response. The attacker appears to have stolen funds through multiple changePosition operations, ultimately withdrawing USDC. Since the contract is not open source, the exact root cause still requires further investigation. Based on on-chain behavior, it is suspected that the incident may be related to unexpected fluctuations in stable balances during early position updates, which led to the release of USDC when reducing or closing positions.
