Perpetuals exchange Ostium has suspended trading after an offchain oracle private key was compromised, leading to an estimated $18.4 million in losses. According to Techub News, citing NewsBTC, the attacker manipulated price feed data using the leaked key rather than exploiting a flaw in the platform’s smart contracts. Ostium said the incident did not directly affect its contract code and instead occurred in the offchain infrastructure that supplies data to the system. The platform has paused trading while it investigates the breach. The case draws attention to a persistent risk for DeFi protocols: how oracle keys are stored and managed outside the chain can become a critical point of failure, even when onchain contracts themselves are not directly breached.
