Reminder that Proton is not "private". They have all the keys, and willingly operate in a jurisdiction where they bend over backwards for ridiculous court orders.

From their own transparency page:

Number of legal orders: 6,378

Contested orders: 407

Orders complied with: 5,971

They did this to expose protestors and people who upset the powers that be, rarely real criminals.

They could choose to operate in a country that respects rights and design their tech so that there's nothing valuable to hand over. This is what Mullvad did.

*Edit: HN has been overwhelmed with poor quality users and bots growing in the last few years. Same as reddit there are paid services used to manipulate voting. HN needs to migrate away from this in order for real discussions to return.

You should back up your claim of "they have all the keys", because for things like email and file contents they claim they cannot decrypt them because they do not have those keys (which you have said they do).

I believe it was stated on the page you copied those stats from https://proton.me/legal/transparency

> As stated in our Privacy Policy, all emails, files and invites are encrypted and we have no means to decrypt them.

[gobip]

They're all encrypted by themselves and if you use your own gpg key they will replace it.

They're all encrypted except when you pay more for dedicated smtp.

They're all encrypted except when they give up logs they promised they didn't have.

And so on.

[protonmail]

This is pretty inaccurate. Proton's E2EE works by encrypting client side, and we can't just replace the GPG key because we have both key pinning and key transparency: https://proton.me/support/key-transparency

Proton does not claim no logs and has never claimed no logs. We do not retain logs by default, but our privacy policy has always been clear that we are legally obligated to follow Swiss court orders, which can ask for IP logging on specific accounts.

[WhackyIdeas]

Listen, if you don’t trust their ProtonDrive - GPG encrypt before uploading. If you don’t trust their email, GPG your message and paste it in or include as an attachment. There are a lot of ways to be able to use proton without trusting them… and if you are an activist of any sort, like just stop oil or cnd, then I am sure they will be doing all of that.

I am not an activist so I don’t need to jump through such loopholes.

I don’t despise proton as much as I despise most of Silicon Vally though. I just hope they fight every single court order, because there will be lots of good people being targeted. However, I reckon that is wishful thinking.

[jszymborski]

Cryptomator is great for the ProtonDrive example: https://cryptomator.org/

[WhackyIdeas]

Cool idea. But, if I personally wanted that functionality I would code my own solution with a shell script I think (because it is super easy to do).

[devwastaken]

Proton has the burden of proof, and has continually failed to ensure their systems are E2E. They have failed to develop better tech like signal, and continue to change their infrastructure to appease swiss orders that come from other countries.

They have every means to decrypt, they control both the client software, server, and data. You would never know if they logged your key, and they can be compelled to by flimsy order.

[protonmail]

This is inaccurate. First, Swiss law does not allow the breaking of E2EE. All of Proton's client side code is open source. We cannot arbitrarily change keys in an undetected way due to Key Transparency: https://proton.me/support/key-transparency. We also have open source mobile and desktop apps, so you don't even need to rely on the web app if you don't want.

[ImJamal]

How do the emails get decrypted then? I imagine your password would decrypt the keys which would allow them to decrypt the emails?

It seems like the next time you log in they would be able to capture your password and decrypt your emails.

[roomey]

There is an FAQ. They sat the emails get decrypted in your browser, or in the "bridge" which runs locally.

Your decrypted key isn't sent off your local computer. So it's not a case of waiting for you to log in and swipe your key. They never get the key.

In the past you could have a separate login password and decryption password. You still can in the advanced settings if you want.

[ImJamal]

The key has to be on their servers though? If I log into a proton account on a new computer I could see all my emails decrypted. I don't have to store the key somewhere and move it to my new computer.

Second, I am not talking about swiping the key, but the password. When you log in, you send your password to their server. They presumably hash the password and compare the hashes then send you the decryption key if the hash is correct.

The problem with that is they could keep the password you entered (pre hash). If hashes are good then use the password you entered themselves with the key to decrypt your email.

It sounds like the separate decryption password may work around this, but is not the default meaning a large chunk of the users are vulnerable to proton logging passwords.

[FranckRJ]

You never send your password to their servers, they use the "secure remote password protocol" : https://en.wikipedia.org/wiki/Secure_Remote_Password_protoco...

They explain what they do here : https://proton.me/blog/encrypted-email-authentication

[WhackyIdeas]

I have been with Protonmail since 2014. And I feel that they are essentially now the same as any other company which makes loads of dollar - they give up their values.

Don’t get me wrong, I have multiple ‘Visionary Accounts’ but I have just no expectation of them protecting my data completely.

How do they get peoples passwords / keys? Easy. They just wait for you to log in and they swipe it then. It’s targeted.

They are a perfect example of why you cannot really trust any company selling ‘privacy’, like Apple, Mozilla and whoever else fakes it. Even TOR to a degree is a pile of pish because all the relays can be hosted on mostly American VPS companies… so although the rest of the world would struggle detecting who people are, five eyes are in an excellent position to be able to unmask. It’s intended for the Five Eyes spies to hide among - they need the randomers on there or it’s a useless tool for their global spies to use - I don’t think enough people actually realise that.

[protonmail]

>How do they get peoples passwords / keys? Easy. They just wait for you to log in and they swipe it then. It’s targeted.

Under Swiss law, Proton cannot be compelled to do this. Nor is this "easy" to execute if you are using the open source mobile or desktop apps.

[WhackyIdeas]

Ok, I may have made an incorrect assumption (sorry).

But, do you have a method which results in the data being accessible to anyone other than the account owner?

I don’t know exactly what you provide. Or how you do it. But it does feel secretive, and that in itself makes people think the worst.

But I do know how NDA’s work, so that might be a part of it.

[protonmail]

No, in fact we have no way to decrypt the emails on our servers, nor can we share them in an unencrypted format with any third parties (law enforcement included). All the data requests we comply with only include metadata which needs to remain unencrypted for the services to function properly.

[hombre_fatal]

Besides, none of it really matters when their customer service backdoor lets you into an account if you can enumerate recent emails that account has received. I'd never trust anything serious with Protonmail. (Try it)

[ivan_gammel]

Do you have any evidence for this claim?

Here’s their recovery process: https://proton.me/support/set-account-recovery-methods

I don’t see there customer support call as a recovery method. I‘d expect that for paid accounts you could theoretically verify your identity to CS via payment, but in that case you lose the data anyway.

[roastedpeacock]

Even if the attacker cant decrypt existing e-mail the concern is by hijacking the account they can intercept future e-mail received such as password resets.

Some searching finds this comment. [1] I would be interested if such a password reset were possible against someone who for instance had 2FA enabled, no recovery information and only accessed their account using the Tor onion-service. ;-)

[1] https://news.ycombinator.com/item?id=19367063

[WhackyIdeas]

Tor onion service relays are mostly on VPS. And those VPS are mostly American.

The number of tutorials I have seen about spinning up a tor relay on a VPS is crazy. These tutorials are probably written by three letter agencies - though I have no proof.

Regardless, protonmail doesn’t let people register when connecting with Tor unless you use phone number or card to make a payment. You will have to give up something which identifies you, and so it really doesn’t matter when you connect with Tor after you have already registered - there is a way to connect who you are.

[roastedpeacock]

Traffic of onion-services is encrypted. Traffic correlation to deanonymize the client can still be theoretically performed but ultimately you need to draw the line in the sand somewhere.

> Regardless, protonmail doesn’t let people register when connecting with Tor unless you use phone number or card to make a payment

Actually if you attempt enough times you will get the option to verify the registration with an e-mail. And they are rather liberal with which options they accept. So it is not exactly a circular dependency.

From there is it an exercise to the reader to create an account not linked to any other identity.

[ivan_gammel]

Valid point, however that happened at least 5 years ago. Proton was smaller. I don’t know if this is still the case for today: I would expect that they continuously improve security of user accounts as they grow.

[hombre_fatal]

Your link doesn't apply here. The attacker's recovery process is to just send an email to [e-mail] and start flapping their gums.

It doesn't matter if you lose data. If you control an email address, you get all future email including forgot-my-password emails.

[protonmail]

Honestly, if you try it, you will find it doesn't really work this way. A lot of heuristics are used for recovery, many which are not visible to the outside for security reasons. Also, data recovery is never possible because of the use of zero access encryption.

[hombre_fatal]

Protonmail's customer service agent CCed my recovery email (me) in the email thread where the attacker was social engineering them. And the attacker was successful until I had to reply to the email chain myself to tell them to stop.

And yes, signing up to Home Depot's email newsletter and other services so that they could tell the customer service agent "my last few emails were from Home Depot and ..." was successful against their customer support system. That's just how amazing it is.

Finally, I don't expect the social media guy running protonmail's HN account to give us much insight into protonmail's customer support security issues, but if you're going to show up, I would've at least expected you to forward my email somewhere for follow up.

[protonmail]

Just providing the information on the most recent correspondents is never enough to provide access to a Proton account. Please share your support ticket number with us so we can see what happened exactly.

[WhackyIdeas]

Thank you. Is there any way you can share the exact things you do or provide when you are forced by a court order to give data about someone?

[protonmail]

You can learn more in our Privacy Policy: https://proton.me/legal/privacy and Transparency Report: https://proton.me/legal/transparency.

[WhackyIdeas]

Can you explain more about this, I am clueless to this? Appreciated!

[drio0]

Are you aware of a better alternative? I am trying to see if I should commit to using Proton or not. I am just a normal users who do not want to be tracked or my data used. Maybe Proton is still very decent for that

[WhackyIdeas]

Not really, no. Unless you want to self-host in your own home hardware.

[freehorse]

> They did this to expose protestors and people who upset the powers that be, rarely real criminals.

Source? How exactly do you know what cases of people the legal orders were about?

[hi-v-rocknroll]

Yep. They fail Lavabit-style, but somewhat worse. They're selling security theater.

[notaustinpowers]

From the same transparency report page, they refuse any requests from countries that are not Switzerland, and only provide information to Swiss authorities when necessary (I.E. valid international legal assistance, violations of Swiss law, etc).

As well, emails and files are encrypted. And their VPN is a no-log VPN.

Lastly, they can comply with an order and just give them nothing, because they don't have anything they can give. No files (E2EE), no VPN network info (No-logging), no emails (E2EE), etc. That's still, legally, an order they complied with.

[theultdev]

Generally it goes like this:

1. Government entity (usually the US or EU country) pressures the host country's government

2. Host country's government makes a legal request to the company for info on this user.

3. Company adds logging for that specific user.

4. Logging is provided to all those interested.

5. Host country prosecutes (potentially extradites).

There's a public accounting of this happening for Proton and Mullvad too iirc.

[notaustinpowers]

You're making multiple conjectures to get to that conclusion, of which the only evidence presented is another company based in a different country than Proton.

It may be true, it may not be, but there needs to be more information or facts before we get to the original comments statement that Proton gives data to expose protestors to protect "the powers that be".

[theultdev]

I'm not making conjectures, these events happened.

That's the flow of how government legal requests work with no-log vpn services.

What do you think "Orders complied with" means then?

Here's an instance of Proton adding logging of an activist's IP Address and Device ID after a request from the French authorities:

https://techcrunch.com/2021/09/06/protonmail-logged-ip-addre...

> French police sent a request to Swiss police via Europol to force the company to obtain the IP address of one of its users.

It's right there in the police report.

[notaustinpowers]

If a government says "Give us everything you have on this user", and Proton gives them a sheet of paper that says "Here's the primary email for the account, we don't have access to anything else", the order is legally complied with.

Granted, I don't know much of how Swiss legal processes work, but I do know Switzerland has the best privacy laws when it comes to VPNs (which is why a lot of VPNs use Switzerland). Switzerland even has laws on their books that prevent them from compelling no-log VPNs based in Switzerland to log specific users.

[theultdev]

I provided an instance of Proton giving the IP address and Device ID of a user after the French authorities requested it.

In their own policy:

> “In addition to the items listed in our privacy policy, in extreme criminal cases, ProtonMail may also be obligated to monitor the IP addresses which are being used to access the ProtonMail accounts which are engaged in criminal activities.”

So there's no question whether or not they do it, it's more of how often they do it and for what. The French case was a big deal because it didn't seem to meet the "extreme criminal case" threshold, and yet the logging was still carried out.

[xandrius]

Switzerland is one of the few countries not instantly putting up with US demands, so it's not that clear and obvious.

[tredre3]

I agree with you that Proton is security theatre. Even if they were truly benevolent, they ultimately control both the server and the client. It would be trivial to serve a special js to a specific user to capture their key. Nobody would ever know. But that part:

> HN has been overwhelmed with poor quality users and bots growing in the last few years. Same as reddit there are paid services used to manipulate voting. HN needs to migrate away from this in order for real discussions to return.

is absurd. Is it really the only way you can explain why you're downvoted? Could it not be because you've made several unsubstantiated claims?

[aniviacat]

You can choose to only use the open source apps. Using the website is optional.
