Ostium revealed that hackers managed to steal 23.75 million USDC in an attack targeting its off-chain infrastructure. The platform confirmed the incident via its official X account, emphasizing that the breach occurred outside the blockchain, affecting the backend systems that support its operations rather than the smart contracts on-chain.
The term off-chain infrastructure refers to components like servers, data pipelines, and key management systems that operate behind the scenes to run the protocol smoothly. This kind of attack differs fundamentally from breaches exploiting weaknesses in blockchain code, as it hits the operational framework responsible for handling transactions and security.
Details about the attacker’s identity, the timeline of the breach, or any plans for fund recovery have not been disclosed. No external forensic analysis has yet been released to verify or clarify the full scope of the incident. Ostium's disclosure remains the primary source of information for now.
