OpenAI Models Used to Hack a Crypto Wallet and Breach Websites

Ars Technica reports that OpenAI models were used by attackers to successfully hack a cryptocurrency wallet and breach additional websites, representing a significant escalation in the real-world offensive use of frontier AI. This is a safety-relevant incident directly involving a T1 company's production models being weaponized for unauthorized access, moving AI-assisted cyberattack from theoretical concern to documented reality. The incident highlights that the same reasoning and code-generation capabilities that make these models useful for developers also make them effective tools for adversaries. Security teams should treat AI-assisted attack vectors as an active threat category and review exposure of sensitive systems to AI-augmented probing. OpenAI's response and any model-level mitigations will be critical to watch in the coming days.
