Comment on Proton’s Lumo AI chatbot: not end-to-end encrypted, not open source
hansolo@lemmy.today 3 weeks agoMy friend, I think the confusion stems from you thinking you have deep technical understanding on this, when everything you say demonstrates that you don’t.
First off, you don’t even know the terminology. A local LLM is one YOU run on YOUR machine.
Lumo apparently runs on Proton servers - where their email and docs all are as well. So I’m not sure what “Their AI is not local!” even means other than you don’t know what LLMs do or what they actually are. Do you expect a 32B LLM that would use about a 32GB video card to all get downloaded and ran in a browser? Buddy…just…no.
Look, Proton can at any time MITM attack your email, or if you use them as a VPN, MITM VPN traffic if it feels like. Any VPN or secure email provider can actually do that. Mullvad can, Nord, take your pick. That’s just a fact. Google’s business model is to MITM attack your life, so we have the counterfactual already. So your threat model needs to include how much do you trust the entity handling your data not to do that, intentionally or letting others through negligence.
There is no such thing as e2ee LLMs. That’s not how any of this works. Doing e2ee for the chats to get what you type into the LLM context window, letting the LLM process tokens the only way they can, getting you back your response, and getting it to not keep logs or data, is about as good as it gets for not having a local LLM - which, remember, means on YOUR machine. If that’s unacceptable for you, then don’t use it. But don’t brandish your ignorance like you’re some expert, and that everyone on earth needs to adhere to whatever “standards” you think up that seem ill-informed.
Also, clearly you aren’t using Proton anyway because if you need to search the text of your emails, you have to process that locally, and you have to click through 2 separate warnings that tell you in all bold text “This breaks the e2ee! Are you REALLY sure you want to do this?” So your complaint about warnings is just a flag saying you don’t actually know and are just guessing.

Yes, that is exactly what I am saying. You seem to be confused by basic English.
They are not supposed to be able to and well designed e2ee services can’t be.
I know, yet proton is happily advertising one. Just read their page.

So then you object to the premise any LLM setup that isn’t local can ever be “secure” and can’t seem to articulate that.
What exactly is dishonest here? The language on their site is factually accurate, I’ve had to read it 7 times today because of you all. You just object to the premise of non-local LLMs and are, IMO, disingenuously making that a “brand issue” because…why? It sounds like a very emotional argument as it’s not backed by any technical discussion beyond “local only secure, nothing else.”
Beyond the fact that
So then you trust that their system is well-designed already? What is this cognitive dissonance that they can secure the relatively insecure format of email, but can’t figure out TLS and flushing logs for an LLM on their own servers? If anything, it’s not even a complicated setup. TLS to the context window, don’t keep logs, flush the data. How do you think no-log VPNs work? This isn’t exactly all that far off from that.

I object to how it is written. Yes, technically it is not wrong. But it intentionally uses confusing language and rare technical terminology to imply it is as secure as e2ee. They compare it to proton mail and drive that are supposedly e2ee.
loudwhisper@infosec.pub 3 weeks ago
Only drive is. Email is not always e2ee, it uses zero-access encryption which I believe is the same exact mechanism used by this chatbot, so the comparison is quite fair tbh.
hansolo@lemmy.today 3 weeks ago
It is e2ee – with the LLM context window!
When you email someone outside Proton servers, doesn’t the same thing happen anyway? But the LLM is on Proton servers, so what’s the actual vulnerability?

You’re using their client. You get a fresh copy every time it changes.

If you insist on being a fanboy than go ahead. But this is like arguing a bulletproof vest is useless because it does not cover your entire body.

Or because the bulletproof vest company might sell you a faulty one as part of a conspiracy to kill you.
