Limiting AI's external access points reduces the attack surface for prompt injection, but shifts the security burden to the user to ensure internal data hygiene.

- OpenAI announced Lockdown Mode, a new ChatGPT setting that disables live web browsing, web image retrieval, deep research, and agent mode.
- Lockdown Mode is intended for users handling sensitive data to reduce data‑exfiltration risk from prompt‑injection attacks, though OpenAI acknowledges it may still be vulnerable via cached content or uploaded files.
- OpenAI is initially rolling out Lockdown Mode to self‑serve ChatGPT Business accounts and eligible personal accounts.
Why it matters: Enterprises and professionals handling confidential information gain a tighter barrier against data leakage via prompt injection, while attackers lose a reliable vector through live browsing and web‑sourced content.
