Odaily News: Headline: "Loss of 23.75 Million USDC: Ostium Price Data Attacked". According to Ostium's monitoring, Ostium has released an update on the security incident. Its liquidity provider treasury was attacked on July 15, resulting in a loss of 23,752,746 USDC. Preliminary investigations indicate that the attacker compromised the off-chain infrastructure that supplies price data to the protocol, submitting disguised, fraudulent price reports. By rapidly opening and closing multiple large positions, the attacker extracted artificially generated profits from the treasury. Ostium stated that trader collateral is stored in separate, isolated smart contracts and was unaffected by this incident; all trading positions remain open. The team paused trading and froze all trading contracts within 60 minutes of the first attack transaction. Currently, Ostium is cooperating with Mandiant, zeroShadow, Collisionless, SEAL 911, and law enforcement agencies, and is coordinating with trading platforms, bridge contracts, and stablecoin issuers to advance the investigation. The engineering team is repairing and strengthening the relevant infrastructure to support a safe resumption of trading. Ostium stated it will notify at least 24 hours in advance before thawing the trading contracts. Once trading resumes, existing positions will be marked at the price at the time of reopening, unaffected by price fluctuations during the suspension.
