Ostium pauses trading as security firms report multimillion-dollar oracle exploit
Decentralized trading protocol Ostium paused trading Wednesday after blockchain security firms Blockaid and CertiK reported an apparent exploit of its OLP liquidity vault. Blockaid estimated the exploit resulted in $18 million in losses, while CertiK placed the figure at about $22 million. Both firms attributed the incident to an apparent compromise of Ostiums oracle system, which supplies external price data to the protocol.Source: Ostium Ostium announced on X that it paused all trading after identifying an issue affecting the vault. It subsequently said: “With user security being our first concern, we recommend that all users temporarily revoke approvals for our contracts until we can further investigate the recent incident.” The protocol said its team is investigating and has not yet confirmed the cause of the incident or the estimated losses reported by blockchain security firms. Built on Arbitrum, Ostium is an onchain perpetuals trading platform offering leveraged exposure to 75 trading pairs spanning stocks, ETFs, commodities, indices, foreign exchange and cryptocurrencies.Source: CertiKAlert Related: Crypto hacks fell 47% in H1 but ecosystem is no safer: CertiK DeFi hacks remain persistent challenge The incident is the latest in a series of high-profile attacks targeting decentralized finance protocols this year, despite broader efforts to strengthen security across the sector.
