One person can tell a lie, but a company consists of many people. You must ensure that only few people know of the logging or there will be a risk of a leak.

An intelligence agency already consists of more people than you need to run a VPN service.

Still I think it's easier to avoid the need for more people than necessary. "Just lie" sounds like the easiest solution but on closer inspection maybe it is not?

yeah, I'm using https://proxybase.xyz for this. It's like Mullvad but for proxies. No kyc, no email but supports xmr.

Is this your service? Since you've made seven posts to HN about it and also your username shows up in the commits on their GitHub. Because I'm quite curious on where the IPs are from. Usually residential IPs is a fancy wording for malware infested devices from regular people.

Ohh, that makes sense haha.

@m00dy: please disclose when you’re talking about your own projects! It’s okay to plug your stuff sometimes, just be honest about it :-)

VPNs are not snake oil. They transfer the trust of your internet activity from a place of low-trust, your ISP, to a place of high-trust, ideally a trustworthy VPN like Mullvad, IVPN, or Proton. Among other benefits. If you don't like your ISP creating a profile of you and selling it to target ads to you, you should use a VPN. >Should I use a VPN? Yes, almost certainly. A VPN has many advantages, including: 1. Hiding…

> place of low-trust, your ISP, to a place of high-trust, ideally a trustworthy VPN like Mullvad This is highly subjective statement. Almost all commercial VPN services farm and sell your data. Just by that, my ISP is definitely high trust point while any commercial VPN is a low trust.

Could you please provide proof for such findings about eg. Proton and Mullvad?

Because if you lie you get infinitely more data than if you don't lie. And if you lie you can do it completely in secret whereas if you don't lie you get articles like the OP exposing the teeny amount of data you're trying to collect. It makes no sense.

Your ISP farms and sells your data too. Most VPNs are untrustworthy, but unlike ISPs, you can choose from any VPN provider in the world, not just the two or three that are local to you. And there are VPN providers in the world that have been proven not to retain data by audits + actual court cases where the court determined that the VPN provider did not have the data authorities were seeking. Do your research and cho…

Deutsche Telekom in Germany/EU farms and sells my data? Any sources?

Even if it farms and only stores your data (which it does) without selling isn't good. YMMV between EU countries but I think even torrenting in Germany is way less safe than eg. in Poland where nobody bats an eye.

I work at Mullvad. (co-CEO, co-founder) Some aspects of the described behavior are as we intended and some are not. The cause is not exactly as described in the blog post. As for mitigation, we are already testing a patch of the unintended behavior on a subset of our infrastructure. If any of you try to reproduce the blog post's findings you may get confusing results throughout the day. We will also re-evaluate wheth…

Within the realm of possibility? Let's be honest, if you are a top NSA executive and you couldn't find a way to get your hands on Cloudflare's private keys (bribing or threatening the right person), you are not getting your Christmas bonus.

It is of course inconceivable that the NSA do not have the private keys for dozens of browser trusted certificate authorities That nonetheless doesn't help them unless they are doing active MITM. In order to do that they'd have to have at least some physical presence at Cloudflare or on the path to Cloudflare.

My understanding is that they tapped communication nodes before. I would be surprised if they can't tap the pipes to cloudflare.

I could just...lie.

Well, there should only be a few people with the access needed to discover logging is happening. Just put the logging configuration in whatever secure configuration management tool is storing your TLS keys and suchlike.

Make it look like an accidental misconfiguration and if an insider who isn't an NSA mole does somehow discover the logging, there's a fair chance they'll turn a blind eye anyway. After all, if you work at a VPN, publicly outing your employer for logging will tank the business, then you and your colleagues will all be out of a job.

That’s been my pet theory from day 1, and not because of DDoS. Simply because they are the SSL terminator for most of the internet and can see anything going on in cleartext (and I’ve seen them protecting some shady stuff) I recall a PRISM slide showing the diagram of Google and the public internet, with a big arrow on GFE saying, quote, “SSL added and removed here! :-)” If NSA aren’t installed at Cloudflare, I wonde…

That slide was about the NSA sitting inside Google data centers without Google's knowledge. That doesn't mean collusion

That's the thing though: We can't know that.

I maintain a list of "23034 IPs to blocklist.txt" blocked IPs they contain all VPN providers. Often VPN providers seed Geofeeds with wrong data, this is why i use traceroute and ping network to locate their real location.

I have a script that logs IPs for any traffic coming in to my servers on ports that don't accept traffic. I then block those IPs from accessing ports behind which there are services. If they're checking my locked doors, I don't want them coming in my unlocked doors.

Closed ports are not "locked doors", and open ports are not "unlocked doors"

That is a binary thought process with a lot of assumptions. You might introduce even more attack surface in pursuit of this "security" measure by installing additional software like fail2ban, for example. Close your ports, maybe assign a non-standard port to the popular ones (like SSH) to reduce log spam, and patch your server often. Anything more complicated than that is not worth it, IMO.
