Probably influenced by Apple's feature with the same name: https://support.apple.com/en-us/105120
I imagine that enterprise companies will be quite interested in this.
> reduce the risk of data exfiltration
Yet, their tools such as codex are able to read ALL FILES on my PC without explicit permission unless you spawn them within a container: https://github.com/openai/codex/issues/2847
It seems like OpenAI stealing sensitive data from their customers is not a big problem for them as it has been reported as an issue for almost a year now and currently has the 2nd most upvotes among open issues (they work on issues based on upvotes, so they claim).
"Prompt injection is not currently a major risk, but its impact could grow as attackers develop more sophisticated methods." - that's such a weird statement to make. It's one of the most significant factors limiting the adoption of the technology in business.
I have mixed feelings about this feature. We're playing with tech that's supposed to do human-shaped things but can't be trusted nearly as much as a human employee (and can't be held responsible for what it does). Restricting the tools available to that patently untrustworthy entity doesn't solve the problem, it just makes the entity less useful, forcing you to sooner or later let it out of the jail.
Is this an admission that prompt injection attacks can indeed not be blocked by an analysis based technique?
If so many tools are straight up blocked, I would be very sceptical of the quality of the results.
Wow, it’s almost like you can use it as if you’re just calling the LLM directly. What a crazy innovation!
So we still don't have a reliable way to separate instructions from data when talking to an LLM, a problem that humans learned how to solve decades ago in areas like SQL and memory safety. But hey, we have these hopefully-not-leaky containers, which are probably implemented with just more system prompts.
How long until somebody figures out how to trick Codex into disabling Lockdown Mode for you?
The help doc explicitly carves out Codex: "Lockdown Mode does not affect network access in Codex." The mode limits outbound requests in chat to block prompt injection exfiltration, but Codex network access is a separate setting. An enterprise team that turns on Lockdown Mode while using Codex against internal repos still has an open outbound path this mode doesn't cover.

On the one hand this is exactly the right solution to prevent lethal trifecta exfiltration attacks.
The existence of lockdown mode does however imply that ChatGPT, in its default settings, does not provide robust protection against sufficiently determined data exfiltration attacks!
