Incident Overview
KUKUCoin, a copycat ERC20 token trading on UniSwap, was exploited in an exit scam on August 13, 2023. The total profit for the attacker was 54.53 ETH or 100,335 $USD.
The scammer initially bought KUKUCoin tokens for 10.65 ETH and then added additional liquidity using the newly bought tokens for 47.87 ETH. After a certain period, the attacker proceeded to remove the liquidity through three transactions, totaling 113.05 ETH. The total profit reached 54.53 ETH, and part of the stolen funds was transferred through multiple EOA addresses, while the other part remains at the attacker's original address.

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 KUKUCoin, these are the critical security checks that could have prevented this incident (August 2023).
- Verify all logic paths related to Rugpull 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
