Security Agency: FutureSwapX Contract on Arbitrum Chain Suffers Nearly $400,000 in Losses

Odaily News According to BlockSec monitoring, a suspicious transaction occurred on the FutureSwapX contract on the Arbitrum chain, with estimated losses 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. As the contract is not open-source, the exact root cause requires further investigation. Based on on-chain behavior, it is suspected that the incident may be related to unexpected changes in stable balances during early position updates, which led to the release of USDC when positions were reduced or closed.
