Beanstalk loses 23 billion yen due to frequent flash loan attacks on DeFi (decentralized finance) platform



Beanstalk , one of the decentralized finance (DeFi) platforms described as 'decentralized' because it doesn't have a central presence like a cryptocurrency exchange, was targeted by attackers for $ 182 million. It is reported that a considerable loss of about 23 billion yen was made in Japanese yen.

The attacker used one of the characteristic mechanisms of DeFi, a ' flash loan ' that allows you to borrow and repay a loan within one transaction without collateral and interest.

According to Beanstalk, the attacker used a flash loan to transfer about $ 76 million in user assets to the attacker's wallet at around 12:24 Coordinated Universal Time. He said he did.

PeckShield, which handles security and data analysis related to blockchain, estimates that the amount of money that the attacker got is over $ 80 million (about 10.3 billion yen), and the total damage will be even more. News sites such as Bloomberg, The Guardian, and The Verge report a total of $ 182 million.






There have already been multiple reports of attacks that abused the 'flash loan', and in August 2021, the DeFi platform Cream Finance lost 3 billion yen, and in the first half of 2021 alone, a total of 52 billion yen. There has been considerable damage.

It is not clear if this attacker was involved in any of the past attacks. It has been confirmed that the attackers donated $ 50,000 worth of virtual currency (about 32 million yen) to Ukraine.
