OpenAI has begun rolling out a new Lockdown Mode<\/b> to ChatGPT for eligible personal accounts to reduce the risk of data exfiltration arising from prompt injection attacks.<\/p>\n

The feature is primarily designed for people and organizations that handle sensitive data and require stricter protection guarantees. Lockdown Mode is available to logged-in users across Free, Go, Plus, and Pro, and self-serve ChatGPT Business plans.<\/p>\n

\u00abLockdown Mode is an optional advanced security setting that limits many tools and capabilities in OpenAI products that can connect to the web or external services,\u00bb OpenAI said<\/a>.<\/p>\n

\u00abIt is designed to reduce the risk of data exfiltration from prompt injection attacks by limiting outbound network requests, at the expense of disabling or limiting some useful features.\u00bb<\/p>\n

The safeguards are aimed at hardening the attack surface against prompt injections, which continues to be a \u00abfrontier\u00bb problem impacting all large language models (LLMs).<\/p>\n

Specifically, they build upon sandboxing and existing controls to combat URL-based data exfiltration mechanisms<\/a> to limit outbound network requests that could potentially transmit sensitive data to attacker-controlled infrastructure.<\/p>\n

The idea is not to stop prompt injections from occurring. Nor does it change the way memory or file uploads work, or the ability to share a conversation. Rather, the goal is to eliminate potential pathways through which the data could be exfiltrated. To that end, Lockdown Mode disables the following features –<\/p>\n
