DeFi Platform Team Finance Loses $14.5 Million in Exploit During Uniswap Migration

On October 27, decentralized finance (DeFi) protocol Team Finance disclosed that over $14.5 million worth of tokens were exploited during the migration process from Uniswap v2 to Uniswap v3. The attack exploited vulnerabilities in the migration function, allowing the hacker to siphon off liquidity and profit from skewed pricing.

How the Exploit Occurred

The hacker transferred liquidity from Uniswap v2 assets on Team Finance to an attacker-controlled Uniswap v3 pair with manipulated pricing. By locking tokens in the contract, the attacker bypassed existing validation mechanisms, enabling them to claim a significant refund as profit. Blockchain security firm PeckShield reported that the initial attack vector required just 1.76 Ether (ETH) to execute.

Uniswap v3's Enhanced Efficiency and Risks

Uniswap v3 was designed to offer improved efficiency for liquidity providers (LPs) compared to its v2 counterpart. However, the transition process between the two versions has introduced new risks. Users must interact with a migration smart contract to transfer their LP assets from v2 to v3, creating potential vulnerabilities that attackers can exploit.

Implications for DeFi Security

This incident underscores the importance of robust smart contract security and thorough testing of migration processes in DeFi. While Uniswap v3 offers advanced features for liquidity providers, the risks associated with transitioning between versions highlight the need for heightened vigilance in the DeFi space.
