Woofun AI reports that perpetual DEX Ostium has suspended all trading activities following a security breach. User positions remain open but unmodifiable, with margins locked within the affected smart contracts. The platform confirmed that approximately 24 million USDC was stolen from its public OLP vault. Attackers converted the funds into roughly 12,080 ETH, transferring 10,540 ETH to Tornado Cash. Ostium is coordinating with SEAL 911 and security researchers while awaiting updates on fund recovery.
