According to CoinDesk, Orion Protocol was attacked by a reentrancy attack, and about $3 million worth of cryptocurrency was lost. The attacker has transferred some of the cryptocurrency to Tornado Cash. In this regard, Alexey Koloskov, CEO of Orion Protocol, stated that all users' funds are safe, including pledges, Orion Pool, bridges and liquidity providers. This problem is not caused by a flaw in the core protocol code, but may be caused by a bug in a mix of third-party libraries in its experimental and smart contracts used by private brokers. Alexey Koloskov also assured users that “no user has suffered any losses in this incident and assets at risk are located in internal brokerage accounts operated by the Orion team for decentralized access to centralized liquidity. Orion Protocol continues to investigate the attack Deposits will not be reopened until activity, bugs are fixed and audited. Users can currently withdraw funds from the Orion Exchange contract.”
