[BlockSec Report: FutureSwapX Contract on Arbitrum Chain Hacked, Losses Estimated at Approximately $395,000] According to monitoring by BlockSec, a suspicious transaction occurred involving the FutureSwapX contract on the Arbitrum chain, resulting in a loss of approximately $395,000. BlockSec stated that they have attempted to contact the relevant team but have not yet received a response. The attacker allegedly stole funds through multiple changePosition operations and ultimately withdrew USDC. Since the contract is not open-source, the specific cause is still under investigation. On-chain activity suggests the incident may be related to abnormal balance changes during early position updates, which released USDC during position reduction or liquidation.
