ChatGPT Lockdown Mode: New Security Against Prompt Injection

OpenAI has launched a new security feature called "Lockdown Mode" for its ChatGPT platform. This update aims to protect users from prompt injection attacks, where hidden instructions can hijack the AI to compromise data or steal information. When activated, Lockdown Mode restricts ChatGPT's outbound communication, preventing unauthorized external network requests. It also deactivates features like the deep research module, automated agent modes, and live internet browsing, making the system rely only on safely cached data. File download features are also blocked. This protective feature is available across all account tiers, including Free, Plus, and Enterprise plans. OpenAI also launched an active session management dashboard. This allows users to monitor and revoke permissions for connected devices or browser tabs accessing their ChatGPT account. This matters because it gives users enhanced control over their data security and privacy.
