Incident Overview
Orion Protocol, an exchange aggregation platform, suffered a reentrancy attack and lost about $3 million in assets. The attackers have transferred some of the cryptocurrency to Tornado Cash. Orion Protocol CEO Alexey Koloskov tweeted that no users suffered any losses in the incident and all users’ funds are safe, including staking, Orion Pool, bridges, and liquidity providers. Assets at risk are held in in-house brokerage accounts run by the Orion team. 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.
