Details of the hack. The experts from the cybersecurity company PeckShield were able to trace the steps of the hack. According to them, the attacker placed a smart contract on the Fantom platform and configured a script to self-destruct, making it difficult to determine which protocol vulnerability he was exploiting.

Using the instant loans feature, the hacker received 80 million USDT, which he used to manipulate the OShare token. After repaying the loan, his profit was about $1,5 million. The attacker then withdrew the funds to Ethereum and ran them through the Tornado Cash mixer.

What do the developers say about the incident? The OneRing Finance team stated that only the OShare liquidity pool was affected and the remaining funds are safe. The project has suspended all operations related to the vault. The developers also offered the hacker 15% of the stolen funds and 1 million native RING tokens for returning the rest and disclosing the vulnerability.
