In a recent tweet by Lookonchain, it has been revealed that Yearn Finance and Aave, two popular DeFi platforms, have fallen victim to a flash loan attack that has cost them over $10 million in stablecoins such as USDC, USDT, TUSD, and BUSD. The attacker executed the attacks in real time and successfully got away with a significant amount of money.
Flash Loan Attacks on the Rise
Flash loans have been increasingly popular in the decentralized finance (DeFi) ecosystem, providing bad actors with a growing number of opportunities to carry out exploits. Data shows that in the first quarter of 2023, over $200 million was lost via flash loan attacks.
Understanding Flash Loans
Flash loans rely on arbitrage, the process of taking advantage of small price differences. Unlike other types of loans, flash loans do not require a lengthy approval process, making them easy to execute. Attackers are drawn to flash loans because they allow large amounts of cryptocurrency to be borrowed without providing collateral.
Preventing Flash Loan Attacks
To prevent flash loan attacks, better security measures, such as code audits and robust smart contract design, can be implemented. Increasing awareness of potential attack vectors within the DeFi sector can also be helpful.
Suspicion Over YFI Deposit Timing
Following news of the attack, some have questioned the timing of the deposit of Yearn Finance’s YFI token. YFI is currently ranked as the most deposited altcoin in the last 24 hours, with 360 YFI deposited to CEX in 67 TXs, all before the exploit. The coincidence is that the YFI token dropped 5% in the past hour, just as the attack was happening.

Some traders have questioned whether the deposit of such a large number of tokens was abnormal or not. At the time of writing, neither Yearn nor Aave have provided a statement regarding the exploit.
