Hackers steal $23.7 million in crypto from Ostium in off-chain attack
Ostium, a crypto trading platform, lost nearly $23.75 million after an attacker compromised the off-chain system responsible for supplying price data to its protocol, draining funds from its liquidity provider vault. The breach did not target the blockchain directly but exploited the infrastructure connecting external data to the on-chain system.
Why this matters: This is a useful reminder of where crypto systems actually break. The blockchain part worked fine. The weak point was the off-chain plumbing — the price feed infrastructure that most users never think about. If you put money into a DeFi protocol, your risk is not just the smart contract code. It is everything feeding into that code from the outside. Liquidity providers lost real money here because of an attack on infrastructure they had no visibility into and no control over. That is the accountability gap worth watching.
