Full title: Mullvad VPN was subject to a search warrant. Customer data not compromised

As a customer, I have no doubt about the "customer data not compromised". I'm a paying customer, yet I have never given them any PII. Great service.

Re:Mullvad VPN was subject to a search warrant by wepple on Thursday April 20, 2023 @08:47AM (#35639107)
Technically they could have been logging your traffic, which is “customer data” even if it doesn’t identify you by name

> Technically they could have been logging your traffic

Of course they “could have” but their entire business depends on them not doing it.

Re:Mullvad VPN was subject to a search warrant by bragr on Thursday April 20, 2023 @09:26AM (#35639581)
That's a specious argument, because the choice could be between logging your traffic and being forced to shutdown under some kind of Swedish NSL, or forced to keep operating and logging even if they want to shut down. Not saying this is what happened, just that your reasoning doesn't really hold. Hell it's entirely possible Mullvad is a honeypot operated by some foreign intelligence service.

What do you mean? Lag 2008:717 does not contain any provisions about forcing companies to log or store data.

Rättegångsbalken does have a provision that a prosecutor can order you to preserve information you already have saved for a maximum of 180 days (https://lagen.nu/1942:740#K27P16S1). I can't find anything about what the punishment for ignoring such an order would be, but to say a company could be forced to keep operating seems extraordinarily unfounded.

Re:Mullvad VPN was subject to a search warrant by bragr on Thursday April 20, 2023 @11:10AM (#35641317)
Try this one [1] which contains an obligation for operators to comply and maintain secrecy. I'm not a lawyer, and definitely not a swedish lawyer, but my point is, despite baked in protections, like most countries, Sweden seems to have a robust set of overlapping national security and surveillance laws.

“Entirely” possible? Sure, I guess it’s “entirely” possible that the NSA is actually controlled by a reptilian, illuminati cabal of extraterrestrials, while we’re just making stuff up without any factual basis whatsoever.

Bad faith responses like this lashing out at people like bragr make me even more suspicious. You know damn well, or should know, that companies secretly being owned by intelligence agencies is something that has happened before and could happen again. Meanwhile there is no evidence at all for reptilian ETs ever existing.

And furthermore, I am sure you know that when dealing with matters of security, it pays to exercise precaution and be wary of scenarios you cannot prove to be happening at the moment. E.g., you don't know your new friend you met at the bus stop is secret police, an informant for the Vichy government, but until you're damn sure he isn't then you don't let him know the location of your resistance safehouse. You don't need to have proof that your new friend has done anything wrong to be cautious of that possibility.

We're assuming in this scenario that your memory is still basically functional, so the math on a sheet of paper won't be replaced suddenly without you noticing.

If you can't even remember things in the medium term that's a level beyond "trapped in a dream" that's much more hopeless.

So, with that assumption, you make a computer solve a problem that's impossible for a human to work through in a practical amount of time. And then you verify it got the right answer. This proves the math wasn't done by your dreaming brain. (At least it proves it to a pretty good certainty, and you can repeat the test.)

Many NP-complete problems are good candidates here for slow solutions and fast verifications.

Service might not collect data but they could be forced with warrant to start doing so for specific entities.

also their business definitely doesn't depend on being honest or standing for their values. there are plenty of vpn's who run on fake marketing that give the impression that they have certain values and do certain things while actually not doing it and they are way more successful than mullvad.

Yes, but Mullvad also doesn’t whore themselves out to any YouTuber that will accept a sponsorship agreement. I’ve never seen an ad for them. I’ve only heard of them from people who tell me they’re the best.

Of course we shouldn’t trust them 100%. Trust isn’t required them competent OpSec is implemented within a workflow. Trust is a vulnerability.

I don't myself. If it isn't on my own infra, I won't trust it.

The idea that folk are keeping passwords in some cloud management portal owned by some company boggles my mind. But this is a very controversial opinion and offends many.

Re:Mullvad VPN was subject to a search warrant by zamnos on Thursday April 20, 2023 @01:00PM (#35642898)
Alright, I'll bite. Not all password managers are the same. In particular, the good ones have no direct access to your data. It's encrypted before reaching them, so even if they get hacked, the attacker can't access your passwords without your master password as well, which hopefully you're not giving out.

You don't have to trust password managers if you don't want to, but if you want others to accept your reasoning as to why, you'll have to convince them using an argument that actually applies.

Re:Mullvad VPN was subject to a search warrant by rft on Thursday April 20, 2023 @02:04PM (#35643806)
While GP didn't spell this out, they have, in my opinion, a point. If you use a cloud portal, usually web based (be it browser, electron or similar), that asks for your master password, you need to trust the provider that the master password is not send to their servers. Even if you trust the provider to adhere to this principle, if their infrastructure is compromised an attacker can serve you a different webapp that sends your master password to the server. Same goes for auto-updating native apps.

This does not render the model of keeping the master password client side only moot, it is more secure no matter what. You successfully mitigate the read-only attack of dumping the storage of the cloud provider. However, if you assume a full, on-going compromise of the infrastructure, your password is not secure anymore.

I get that this is moving the goal posts a bit but I wanted to post this anyway. I think if you have highly valuable credentials and want the maximum security for them, you should play out as many possible attack vectors as possible.

If you're interested in hiding from civil snoops (RIAA, MPAA), by all means, use one. If you're interested in hiding from a government, then by all means, keep rolling the honeypot dice.

If such information is publicly accessible, and it corroborates Mullvad's story here, I'd feel like that's pretty compelling evidence that we can trust that Mullvad isn't simply committing fraud by promising not to log customer data while actually logging it.

Re:Mullvad VPN was subject to a search warrant by larsnystrom on Thursday April 20, 2023 @04:56PM (#35646167)
When the prosecutor brings forth the charges to a court, this information will be public. Until then it is probably covered by “förundersökningssekretess”, which just means that ongoing investigations are not public.[0]

You can contact the “Åklagarmyndigheten” (the Swedish prosecutor authority) and ask them and they’ll help you out. Generally speaking it is pretty easy to get information from government agencies in Sweden due to our constitution. Everything is public by default, with some exceptions like military secrets. I think it shouldn’t be a problem for the prosecutor to confirm they had a warrant at Mullvads office, and maybe even to confirm they didn’t seize anything, unless they think it could harm the ongoing investigation somehow.

Anonymity is not binary. It's a spectrum. Phyical cash mailed to a company with only an account number is significantly more anonymous than a check or credit card they bill.

Perfect anonymity is probably impossible because information theory is impossible to escape. Which means you are trying to determine how far along the spectrum you can reasonably get for your particular risk profile.

Comments that pretend like perfect anonymity is the goal or act like it's binary are singularly unhelpful.

So, yes, there is a theory that someone may go in the trash in Sweden, finds the envelope, the stamp (and it has to be a british one), investigate who bought the stamp, get the assistance of the shopkeeper in UK (without raising suspicions), successfully reviews tons of security cameras footage to find who bought, etc.

And still don't know which activity to link it to.

A perfect waste of public resources if the NSA really does that, when all they needed to do is to purchase a VPN provider or fund Tor and claim to be no-logs VPN ;)

Presumably the theory is more like [1] - that the postal service, when they scan the envelope to read the address, save the scanned image and give it to the cops.

I agree that the NSA would be better off just running their own VPN services - or indeed intercepting everything on major backbones and just seeing what source IPs connect to Mullvad's servers.

Storage is cheap - really cheap. I bet automatically capturing images of all mail during sorting and archiving that for years is not only viable, but a vital investigation/intelligence tool. One would ask Mullvad for the cash payment dates[1], and cross-reference with all mail sent to a Mullvad postal address. One city-level datapoint on where user was, cross-checked with the latest IP address, where stamps were bought, and you've massively trimmed the list of suspects, especially if they are behind a NAT and sharing the IP.

1. They have to keep track of payment dates, which is a side channel.

Possible, quite easy, and certainly of political value. But, you know, maybe they're not.

It's all metadata correlation.

The UK will know with certainty that a specific stamp was used to send a specific envelope to Mullvad. (e.g., America has been logging images of every envelope that passes through its postal service for over two decades).

It would also be trivial for the UK to know:

- When and where that stamp was initially sold (and to whom, if buying online!)

- When and where an envelope bearing that stamp entered the postal system

- When and where envelopes with other stamps from the same booklet entered the postal system

Add up enough bits and you can pierce anonymity.

And all of this is null and void if you buy your stamps from aliexpress and for the low low effort of simply driving to a different city to throw the envelope into the postbox.

Not really very realistic is it though? I can only imagine this sort of thing is only done if the suspect is someone like Bin Laden, not the average Joe using a VPN for pirating Photoshop.

This is a misconception caused by the scale of surveillance today. In the old days you were right. To do this kind of tracing they'd have to assign someone to do it which takes human resources and is not infinitely scalable. So they'd only do it to people deemed interesting enough, so average Joe was safe.

Today the scope has changed completely. Everything can be correlated all the time, so it is. No suspicion or probable cause needed.

To make this happen each stamp would during product have to know where it would will be sold. Is that actually how it works? Can you show me the evidence for that.
Re:Mullvad VPN was subject to a search warrant by netsharc on Thursday April 20, 2023 @11:01AM (#35641166)
If they scan the stamp's code at time of purchase, and associate it with your debit card, that'd be an obvious way of tracking you.

If they don't do that, if they meet the stamp along the letter's journey, they can scan the code and check which batch it's from, and there could be a database of which post office got which batch, and then it's a matter of checking that post office's purchases/security cameras.

If all stamps are indistinguishable from each other, then you could've bought the stamp months ago on the Isle of Skye and used it in London, they wouldn't be able to tell the difference.

I use https://vpn.sovereign.engineering to pay with Bitcoin.

You can pay a Lightning invoice to get a voucher which is redeemable on the website. You get an extra layer of privacy, and also don't need to wait for an on chain transaction.

Mullvad lets you pay with just an envelope of cash via the mail if you want.
Re:Mullvad VPN was subject to a search warrant by kklimonda on Thursday April 20, 2023 @09:06AM (#35639328)
They also have vouchers you can buy from Amazon, which I find a nice alternative to sending cash in an envelope.
Re:Mullvad VPN was subject to a search warrant by lxgr on Thursday April 20, 2023 @09:21AM (#35639527)
At that point, you can probably just pay by credit card: If your aim is to frustrate invasive ad trackers and profilers on the web (and you assume that Mullvad isn't outright colluding with these), that should be good enough to break any links.

On the other hand, if you don't trust Mullvad's assertion that they delete the link between accounts and credit card payment records after 40 days [1], what makes you think you can trust them to not keep a record of individual scratch cards sold on Amazon, which Amazon can then correlate to an order ID and by extension account and shipping address?

At a higher level, if somebody can convince Mullvad to collude in that manner, they can likely also just ask them to outright hand over your traffic flows and connection data.

Re:Mullvad VPN was subject to a search warrant by kklimonda on Thursday April 20, 2023 @09:50AM (#35639882)
How would they do that? Those are shipped directly from Amazon, and don't have any external markings that could be used to link specific card to amazon account. Unless the idea is that vouchers arrive at amazon in some additional packaging and then are repackaged after linking voucher to the account.

By the end of the day I agree, if you have any "real" reason for using VPN you pretty much have to implicitly trust your provider to not keep any traffic flows and connections that could correlate traffic to your IP, but not even sending money in envelope saves your from that.

Re:Mullvad VPN was subject to a search warrant by r3trohack3r on Thursday April 20, 2023 @11:01AM (#35641167)
I think it goes something like this:

If your worried about anything in a 40 day window the credit card <-> account_id is a liability

Amazon doesn’t know the redemption code on the gift card. So Amazon knows that you purchased a Mullvad gift card, but can’t associate the transaction with a Mullvad account. Likewise Mullvad knows service was paid for with a gift card (possibly that the gift card is from a lot sold on Amazon). But they do not know which Amazon transaction the card is associated with.

Unless your behavior and the behavior of others deanonymizes the Amazon purchase <-> redemption your account should be indistinguishable from any other that purchased a Mullvad gift card from Amazon in that window of time.

If you care about privacy, then Amazon is the last company I would buy from. From personal experience, I would be far more concerned about what Amazon does with your data than Mullvad.

Apparently you can literally mail them cash with your randomly generated user id on a card and they'll top up credit for you.

At least before, one could pay in cash in envelope.
Re:Mullvad VPN was subject to a search warrant by eitland on Thursday April 20, 2023 @09:59AM (#35640037)
Cash in envelope is still welcome.
