ChatGPT can be hijacked without you knowing. Lockdown Mode is the fix

PCWorld reports that OpenAI launched Lockdown Mode for ChatGPT to combat prompt injection attacks that can hijack AI systems and steal personal information. These attacks have previously compromised AI browsers like Perplexity and controlled smart home devices through Google Gemini by tricking systems with malicious instructions. Lockdown Mode restricts features like live web browsing and Deep Research across all ChatGPT plans, though OpenAI acknowledges risks from uploaded files remain. OpenAI has launched a new security feature in ChatGPT called Lockdown Mode, designed to provide additional protection against so-called "prompt injection attacks." A prompt injection attack is when someone crafts a deceptive prompt in an attempt to trick the LLM into following malicious instructions and/or revealing sensitive information.
