The Ostium trading platform disclosed a $23.75 million theft from its liquidity provider vault after attackers compromised off-chain price feeds, creating fraudulent profits and forcing a trading pause. The exploit used illegitimate price reports and rapid position cycling rather than direct theft of trader collateral. Ostium said existing positions remain open and separate trader collateral was not affected. The platform said it is tracking the stolen funds and working to secure the affected infrastructure.
