Incident Overview
Poolz Finance was exploited for 443,439 $USD. The hacker exploited overflow vulnerability to receive assets from the project's vault contract.
Poolz Finance is a launchpad running on Binance and Polygon chains. The project was exploited via overflow vulnerability. The LockedDeal vault contract of the platform was exploited, which caused the $POOLZ token price to drop by more than 95%.
The attacker was able to receive various tokens, after draining the vault contract, and exchanged them for 443,439 $USD worth of $BNB. All the stolen funds remain at the attacker's original address at the moment.

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 Poolz Finance, these are the critical security checks that could have prevented this incident (March 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
