Obscura: The first VPN that can't log your activity

I don't understand the point of this.

Many (if not all) of the benefits on the landing page are available in Mullvad too, which is a more mature and reputable product, has all clients fully open-source, and powers the exit servers for Obscura.

Why should I choose this over Mullvad?

Mullvad is a Swedish company, which has stricter privacy protection laws in place.

According to Obscura's legal page, it is a New York-based company [0]. Under US law, a secretive court order could compel a US company to update software or implement targeted logging on a specific user without notifying that user.

The only scenario where Obscura would be useful is if Mullvad were compromised. Why would I trust a New York company to shield me from a more reputable Swedish company?

We think Mullvad is a great privacy tool, which is why we partnered with them!

As for what's different: We're a Multi-*Party* Relays (vs. traditional VPNs which are Single-Party Relays): https://www.privacyguides.org/articles/2024/11/17/where-are-...

With Multi-Party Relays you no longer have a trust a single entity not being malicious or compromised. More on this here: https://obscura.com/#how

Also, all our apps are open-source as well: https://github.com/Sovereign-Engineering/obscuravpn-client

How do you compare with iCloud Private Relay (with the obvious exception that private relay only works on macOS, and in specific apps only)?
reply
dongcarl 10 minutes ago
We're heavily inspired by them (see our original blog post which is a bit more technical here: https://obscura.com/blog/bootstrapping-trust/)

The differences are:

- We allow you to choose an exit location (I believe iCloud Private Relay restricts you to the same location)

- Our exit hop is Mullvad instead of Cloudflare+Fastly+Akamai

- We use QUIC for transport instead of HTTP/3 (which is built on QUIC and has a bit more overhead)

i am very skeptical of most vpn companies, and while i haven't looked too hard at obscura, it is worth noting the official partnership with mullvad (https://mullvad.net/en/blog/mullvad-partnered-with-obscura-v...) which is certainly a positive signal

side note: i really wish more companies did the no email + randomized account number flow. there is a certain popular "pro-privacy" product beloved by many here that requires an email address and refuses to offer a similar account number method, which has turned me off the product.

Yeah we thought the randomized account number flow was an ingenious idea, so we did that and made the last digit a Verhoeff checksum to check for mistypes!

Though sometimes people forget to write the number down and... There's not much we can do.

for what purpose? there is nothing to be gained from pointing fingers, and takes the discussion in an even more unrelated direction.

although i guess people's curiosity is also dragging my comment in an unrelated direction anyways. lose-lose situation.

my main point is that the account number method is really nice, and a great selling point for such privacy-conscious products. not offering it in a privacy-conscious product is enough signal that it has made me choose not to purchase the product. that's the important bit, and where i was hoping to drive the conversation.

There is even less to be gained by issuing vague unactionable warnings and/or accusations...
reply
john_strinlai 38 minutes ago
it's not a warning or accusation...

this isn't some hidden feature you get caught with your pants down over. if you try to sign up to something and it doesn't offer an account number, you know that it doesn't offer an account number instantly.

no time wasted for you. it's not some nefarious plot by the company.

it's just a business decision. i was hoping to talk about the business decision of that particular sign up flow.

Incorrect. Pointing out bad products is a warning to other people to not waste time on it. We should be doing it more, not less.

I also have no idea what company/service you're talking about

If you're talking about Proton VPN, they do support "credential-less accounts" through their official apps, I believe? At least, on Android since 2024: https://www.androidpolice.com/proton-vpn-works-without-accou...

As others have pointed out, this is like Apple iCloud Private Relay, and other multi-hop privacy systems that have been built on and off over the last several decades (Tor included).

We wrote a research paper on the general principle a few years ago: https://conferences.sigcomm.org/hotnets/2022/papers/hotnets2...

So two hops, basically. First hop sees your IP address but not the website you're going to, second hop sees website but not IP address. Similar to Private Relay: https://support.apple.com/en-us/102602.

But if both services keep logs de-anonymization is a join.

(Carl from Obscura here)

Very true, but if even 1 of (Obscura, Mullvad) is honest, there's no de-anonymization.

For traditional Single-Party VPNs, you just need to compromise 1 party, with Two-Party Relays, you need to compromise both.

They don't even need to. If you observe enough of them you can correlate traffic patterns between them and find out which one is used by which endpoint

Hi Carl, thanks for being here to answer questions. Two questions: Do you have any active testers in Iran right now, and secondly, how is this architected to deal with advanced DPI boxes in ISP networks that detect flows of encrypted traffic and drop it? The methods I'm seeing people use with success from within Iran right now are very different than something like a commercial mullvad or competitor VPN.

Some of them rely on people having a helpful third party in ("free") country to set up a private relay in something like Azure IP space that isn't used by any other VPN users, so it doesn't attract a level of attention (or attention by multiples of different peoples' encrypted flows) that publicly published commercial VPN services do. It's a hard problem to solve on a scale of more than a couple of people.

The multi party relay concept is great, my concerns are more with traffic detection/DPI in between the end user and the first hop in the relay.

Can't speak to Iran, but we use QUIC for transport (with an experimental TCP/TLS mode).

I believe QUIC has been harder to block for censors, esp with Chaos Protection on by default in Chrome. See: https://gfw.report/publications/usenixsecurity25/en/

How does this prove Obscura and Mullvad can't just both gather tracking data and then just combine it on demand?
reply
dongcarl 17 minutes ago
(Carl from Obscura here)

This doesn't prove it. However, Obscura makes it so that there's no *single party* that if hacked or otherwise compromised would hurt your internet privacy.

and how is it better than just connecting to mullvad over nordvpn or something?
reply
dongcarl 15 minutes ago
(Carl from Obscura here)

Other than the obvious hassle? XP

If you connect to Mullvad over NordVPN:

- You're giving both Mullvad and Nord some payment information (with Obscura you only give that to us, Mullvad has no idea)

- You don't get our QUIC-based obfuscation (see more here: https://obscura.com/blog/bootstrapping-trust/)

If you're already a Tailscale user, seems like this solution is nearly identical to using Mullvad as an exit node.

You would go with this solution if you don't trust Tailscale or NordVPN, I guess.

reply
dongcarl 13 minutes ago
(Carl from Obscura here)

I could be wrong but in Tailscale if you use Mullvad as an exit node, the traffic flows directly from your device to Mullvad's servers.

Whereas with Obscura, your traffic flows to the Obscura relay, then the Mullvad exit.

reply

Yes, but your tailnet IP is what is provided to Mullvad's servers. Not your public IP.

This sounds pretty neat, and I do dig the website, though I can’t help but think it’s an odd combination to have bitmap/pixelated fonts and graphics inside perfect squircles.

Seems like you guys have two distinct ideas of a visual identity completely at odds there. Shape contrast is nice and can be rather fun to play with, but it has to be handled with care. Right now it feels like the designer had a bunch of ideas and didn’t know how to bring them together in a cohesive identity.

Bonus point for the TRON reference at the end! “I fight for the users!”

I'm a sucker for retro 8-bit graphics and fun mascots, so we went with that, but when we experimented with 8-bit for actual UI and long text we immediately found it to be super unusable and unreadable :-(

Ah ofc the HN poster knows the reference :-) I've had it as my email signature since high school I think.

Your traffic is still unencrypted by the VPN provider at the other end of the Wireguard connection, I am not sure how this changes that?
reply

So like OHTTP but for UDP traffic? I suppose they are using MASQUE CONNECT-UDP?

They are careful to not exactly claim the same anonymity properties of Tor, though I think a lay reader will read that differently (ie, that they do have the same anonymity property as Tor).

That said being able to verify the inner wireguard conn to mullvad is nice. Of course you have to trust them that they aren't colluding with mullvad to share your identity/ip. But same goes for OHTTP.

Basically a middle-man for a Mullvad VPN, where if Mullvad decides to pull out of their agreement with this company, you lose your connection and are hopefully refunded.

The single point of failure for this product is Mullvad and its leadership's changing opinions.

I don't like 'us vs others' kinda comparisons, it's just marketing trick, which means they care more about sales than your privacy.

Secondly, Mullvad did what Obscura does now years ago.

Furthermore who needs a gamified VPN tool?
