Incident Overview
Aurory, a Solana-based blockchain gaming project, suffered an exploit on Dec 17, 2023, losing 550,000 AURY tokens worth 272,652 USD.
Aurory's SyncSpace bridge on Arbitrum's native DEX - Camelot, was targeted in an exploit. The attacker exploited the marketplace's buy endpoint, inflating their AURY token balance in SyncSpace. This allowed them to withdraw nearly 550,000 tokens to the Arbitrum network and liquidate the stolen amount in the market.The attacker swapped AURY tokens to USDC on the AURY-USDC liquidity pool in 9 transactions.
Stolen funds were distributed among multiple addresses and deposited into Binance and FixedFloat exchanges.

Protocol Information
What the Attacker Needed to Succeed
Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.
What Auditors Should Check
If you're auditing a protocol with similar architecture to SyncSpace, these are the critical security checks that could have prevented this incident (December 2023).
- Verify all logic paths related to Other are guarded by proper access controls and input validation
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
