DeFi Protocol 'Platypus' De-pegged បន្ទាប់ពីការវាយប្រហារដោយ Flash Loan

On February 16, Platypus Finance, a decentralized finance (DeFi) application was affected by a flash loan attack. as per CertiK, a smart contract security firm. In a tweet, CertiK informed that the hacker used flash loans resulting in $8.5 million worth of assets loss. As a result, the Platypus USD stablecoin (USP) became de-pegged from the US dollar. Currently, all operations on the platform have been paused.

Earlier on Friday, the Platypus community confirmed that the attacker targeted a loophole in the USP solvency verification process. “They used a flash loan to exploit a logic error in the USP solvency check mechanism in the contract holding the collateral,”

According to blockchain data, the attacker raised around $44 million for the flash loan from Aave, a lending platform. The borrowed money was used to fund a trading pool on Platypus and fooled smart contracts into releasing $44 million of Platypus’ LP token in return for LP-USDC. A flash loan is an uncollateralized loan where digital assets are repaid the borrowed amount in a single transaction.

At press time, the USP price was at $0.24, down by 0.10% in the last 24 hours. On Friday Platypus community assured the users that they were trying to contact the hacker to arrange a bounty in exchange for the return of exploited funds.

In recent months, other DeFi platforms have been targeted by flash loans, including Deus DAO in April, Nirvana Finance in July, New Free DAO in September and Mango Markets in October. As per US Blockchain analysis, cyber attackers stole 1.3 billion USD from រូបិយប័ណ្ណសម្ងាត់, 97% of which was stolen from DeFi platforms between January and February 2022.
