Ostium issued an update on the attack: price data were attacked and traders' collateral and holdouts were unaffected

On 19 July, Ostium issued an update on the attack. Its liquidity provider bank was attacked on 15 July, resulting in the loss of 23,752,746 USDCs. The preliminary investigation revealed that the attackers had invaded the chain infrastructure that provided price data to the agreement and had submitted disguised illegal price reports to extract artificial profits from the treasury by rapidly levelling many large warehouses. Ostium stated that the traders ' collateral was stored in a self-segregated smart contract, which was unaffected by the incident and that all trading slots remained open. The team suspended the transaction within 60 minutes of the first attack and frozen all the deal contracts. At present, Ostium is working with Mandiant, Zero Shadow, Collisionles, SEAL 911 and law enforcement agencies and coordinating trading platforms, bridge contracts and stabilization currency issuers to advance investigations. The engineering team is focusing on the rehabilitation and enhancement of related infrastructure to support the resumption of security transactions. Ostium states that the contract will be unfrozen at least 24 hours in advance. Upon resumption of the transaction, the existing warehouse will be marked at the prices at the time of reopening and will not be affected by price fluctuations during the suspension period. The affected mobility providers and the safe resumption of transactions remain a priority。
