According to research by Blockchain security firm, PeckShield, the unknown attacker used a flash loan before exploiting the re-entry bug. The firm, which led the initial analysis, detailed the hacker ‘s steps via a tweet


The hacker makes a flash loan of 500 ETH and deposits the funds as collateral .Then, the hacker borrows 19M $ AMP and makes use of the re-entry error to re-borrow 355 ETH within the $ AMP token transfer. Then, the hacker autoloans the loan,” PeckShield

explained. The hacker repeated this process several times to extract the funds.

Based on EthereumAMP is a token that is designed to secure payments on the digital payment network, Flexa. The Amp token contract implements the ERC-77-based smart contract of record, known as ERC-1820. Introduced in 2019, the ERC-1820 standard defines a universal registration contract where any address “can register which interface is supported and which smart contract is responsible for its implementation.”

The PeckShield team told Crypto Briefing media outlet about it that there could be a “risk of composability between Compound-based borrowing protocols and ERC-777-like tokens.”

As a result of the event, both AMP and Cream Finance’s native token, CREAM, experienced a notable price drop. The former has collapsed 8% in the last 24 hours, trading at USD $0.054, while CREAM is trading at USD $163, down nearly 7%.

The respective teams at Cream Finance and Peckshield are still investigating the attack, though they advanced that a post-mortem will be conducted soon.

This is the second time in the last six months that this DeFi platform has been hacked. In February, Cream Finance lost about USD $37.5 million in what was then labeled as one of the largest flash loan hacking attacks.
