Incident Overview
DualPools DeFi project was exploited via a smart contract vulnerability, resulting in a loss of 41,286 $USD.
DualPools, a DeFi project offering Swap, Lend, and Borrow services, was exploited on February 15, 2024. The attacker manipulated the price of dLINK by exploiting insufficient liquidity in a new DualPools pool and depleted targeted assets (WBNB, BTC, ETH, ADA, BUSD) from other pools through the borrow function. Additionally, the attacker exploited a precision truncation issue in the smart contract division, reclaiming all previously invested LINK.
The stolen funds were swapped to BNB, transferred to another EOA, and then after a week deposited into the TornadoCash .

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 DualPools, these are the critical security checks that could have prevented this incident (February 2024).
- Verify all logic paths related to Flash Loan Attack are guarded by proper access controls and input validation - see the Flash Loans Attacks attack class for patterns
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
