ChatGPT Lockdown Mode rolls out to all users to combat prompt injection attacks and data theft
OpenAI has expanded its ChatGPT Lockdown Mode to all users, including free tier accounts, offering enhanced protection against prompt injection attacks that could steal sensitive data. The optional security setting restricts outbound network requests to prevent data exfiltration, though it limits features like live web browsing, Deep Research, and Agent Mode. While the feature doesn't stop prompt injections entirely, it acts as a final defense layer by blocking ChatGPT from sending information to attackers.
