The protocol has suspended all operations on Optimism Ethereum until further notice.
The Cyvers Alerts reviewer clarifies: An unknown attacker first withdrew about $3 million from the protocol, and after completing the first stage, resumed the attack and stole about $ 17 million more. Thanks to the exploit, the attacker withdrew funds using a pair of Circle (USDC) and Wrapped Ether (WETH). Collectively, the Sonne Finance crypto lending protocol could lose assets in the USDC and WETH in the amount of more than $20 million.
The attack is ongoing and much bigger, an additional $17 million has been stolen and the total value loss is more than $20 million. @SonneFinance please take immediate action. https://t.co/k39W09J8Bd

In this regard, the assets of other forks of the Compound, such as LayerBank, Mendi Finance, Orbit on Blast, Ionic and Iron Bank, may be in potential danger.
On the eve of a hacker attack, the decentralized Equalizer exchange was attacked. Reacting to the fact of hacking, Equalizer management asked users to temporarily stop all interactions with the trading platform.
