Hackers steal $23.7 million in crypto from Ostium in off-chain attack

Ostium, a trading platform, lost $23.75 million when an attacker compromised off-chain infrastructure that supplied price data to the protocol, enabling the theft from its liquidity provider vault. The attack exploited the dependency on external systems to feed critical information into the platform's operations.

Why it matters: DeFi platform operators and liquidity providers using price oracle infrastructure face exposure to off-chain compromise; practitioners managing such systems should audit dependencies and implement additional validation layers.
