Devil's advocate - VPN might be better than Tor. Hear me out:
A VPN provider's business is keeping your connection private. They have no incentive to log because the leakage of such logs would be catastrophic. Thus, a reputable VPN provider is unlikely to be a front for a nation-state actor. There is a strong financial incentive for a VPN provider to do their job, as stated, no conspiracies, and do it well.
Tor, on the other hand, has frequently had bad actors comprise a significant portion of running nodes, to the point where being the victim of a correlation attack wouldn't be unlikely for a regular user. Intelligence agencies and bad actors alike have immense incentive to saturate the Tor network with bad nodes. Finally, Tor has been plagued with issues and vulnerabilities, that they seemingly do not have the manpower or technical ability to fix: https://www.hackerfactor.com/blog/index.php?/archives/906-Tor-0day-The-Management-Vulnerability.html https://www.hackerfactor.com/blog/index.php?/archives/906-To...
I suspect that the future of anonymous communication will be a mixnet resistant to correlation attacks (unlike Tor.) An example - https://nymtech.net/ https://nymtech.net/
- elsjaako 5y agoThe major VPNs log, this has been shown in court cases. If they say they don't they're either using a limited definition of log, straight up lying, or about to run into problems with the government. My source isn't an open one, but here is one (that sites different cases than I saw): https://restoreprivacy.com/vpn-logs-lies/ https://restoreprivacy.com/vpn-logs-lies/
- xvector 5y ago> The major VPNs log, this has been shown in court cases. Some VPNs have proven no-log in courts, eg PIA. The VPNs in your article are far from reputable.
- elsjaako 5y agoPurely out of interest, how has this been proven?
- xvector 5y agoWhen asked to provide logs in a legal case, PIA claimed it was unable to as it had none. If you were to tinfoil hat, you could perhaps argue that this is to make PIA an even more viable honeypot. Alternatively, if your conspiracies don't run that deep, this makes PIA more trustworthy than the Tor network.
- waynesonfire 5y agoOkay but to be clear that's not a requirement for the problem being addressed here, which is attempting to get through censorship. Anonymous browsing is a more general problem. I don't think the OP made a good argument that VPN is a suitable solution, but certainly introducing unnesccessary requirements may be disqualifying a possible working solution. Now, if the censor has the power to invoke great harm to those attempting to bypass then anonymous browsing is the requirement.
- elsjaako 5y agoIf you only care about viewing censored materials and don't care about the repercussions of getting caught, then I agree that a VPN is a fine solution. It's probably easier to use and faster for most customers, with the downside that you have to pay.

- Heliosmaster 5y agoI'm not so sure about your argument: the usual argument against a VPN is that you are trusting effectively somebody else's computer. They can have all the business incentives in the world, but we know that some states go knocking on doors with gag orders. A 5$ wrench (or its threat) can get a long way. The point is that we can't easily know who is compromised and who is not. There's always a certain level of trust required. The argument is that if you host your own VPS and use that as exit-node, at least what you're buying is more generic and the VPS provider most likely wouldn't care. But again, it's a matter of trust.
- xvector 5y ago> but we know that some states go knocking on doors with gag orders. Hence the need to buy from a reputable VPN, based somewhere where gag orders are not legal. Personally, I'd believe a carefully chosen VPN provider to be more trustworthy than a random selection of Tor nodes.
- DarylZero 5y agoThe idea behind onion routing is not to have to trust individual nodes.
- xvector 5y agoThis does not work in practice.
- Heliosmaster 5y agoThe issue is that whether a VPN is reputable is hard to gauge and not fixed in time. Take IVPN from example: from what I gather they are among the most reputable. They haven't fucked up yet (a-la Nord VPN), they support and fund anti-censorship activities etc. But all of this is based on a perception, that can be doctored if you're determined enough. And usually in the discussions about VPNs the level of paranoia is pretty high to be trusting others. Furthermore, the real issue is that VPNs are not that widespread among the "general public" so compromising a VPN (or running a fake one) seems like a good target for those who want to get at the (current) typical users of VPN.
- goodpoint 5y agoAny intelligence agency with the ability to monitor the majority of Tor traffic (AKA a global observer) would have no problem at all doing correlation attack against a VPN provider. > Intelligence agencies and bad actors alike have immense incentive to saturate the Tor network with bad nodes Bad node owners largely not cooperate with each other, and this keeps Tor safe. > the future of anonymous communication will be a mixnet resistant to correlation attacks I2P has been around for 18 years. Please do use HN to advertise cryptocurrencies.
- xvector 5y ago> AKA a global observer Between a single malicious node and global observer is the simple act of running many Tor nodes, which is comparatively much cheaper and much easier. > Bad node owners largely not cooperate with each other, and this keeps Tor safe. It does not. Nearly 10% of Tor nodes were run by a bad actor at a certain point this year. About 1 in 300 Tor users were completely deanonymized at that point in time. Much more if you use mobile Tor, which doesn't seem to pin a guard node. "a 16% chance that a Tor user would connect to the Tor network through one of KAX17’s servers, a 35% chance they would pass through one of its middle relays, and up to 5% chance to exit through one." - https://therecord.media/a-mysterious-threat-actor-is-running-hundreds-of-malicious-tor-relays/ https://therecord.media/a-mysterious-threat-actor-is-running... I don't know about you, but a 0.3% chance of deanonymization on every route change is pretty unacceptable. > I2P has been around for 18 years. I2P is not well maintained, it is not a mixnet, and it does not have the same security guarantees as the Nym mixnet. https://blog.nymtech.net/vpns-tor-i2p-how-does-nym-compare-8576824617b8 https://blog.nymtech.net/vpns-tor-i2p-how-does-nym-compare-8... > Please do use HN to advertise cryptocurrencies. Please do not accuse HNers of "advertising cryptocurrencies." Merely mentioning the existence of a tokenized mixnet is not advertisement. We are allowed to talk about obviously relevant technologies, especially ones that improve on existing ones in novel ways.
- goodpoint 5y ago> Between a single malicious node and global observer is the simple act of running many Tor nodes, which is comparatively much cheaper and much easier. And very ineffective, compared to a global observer like PRISM. Tor makes no secret that real time traffic is vulnerable to correlation attacks. It's not a "bug" in Tor, it's true for any data transmission. And VPNs are way, way more vulnerable to such attack. > I don't know about you, but a 0.3% chance of deanonymization on every route change is pretty unacceptable. "unacceptable" is as strange word to use when there are no practical alternatives. Tor would be more resilient if a large number of organizations and individuals ran their own nodes. We can encourage participation. Other than that, the best thing we can do is develop store-and-forward systems on top of Tor that resist timing attacks. Briar is a good example.
- _def 5y agoMilking the market as long as it is possible sounds like another financial incentive to me. A lot of VPN providers make a dubious impression to me.
- hodgesrm 5y agoWhy is this comment being downvoted? I follow HN to get perspectives exactly like this one.
- rank0 5y agoBecause most voters think it’s a shitty take. It’s a hell of a lot easier to identify a vpn user or compel a vpn provider than to perform timing/throughput/correlation attacks on the tor network. Correlation based attacks can take months of consistent observation assuming you control exit and entry nodes the victim is using. Even then you will only identify your victim within some probability. In places where your government is this hostile and you’re doing something subversive you’re probably using an onion service or i2p which vpns cannot access.
- masterof0 5y agoHow is that a shitty take? Tor is compromised, so are most VPNs, but there are some VPN providers that dont store logs (allegedly) like Mulvad. I would take a maybe-is-compromised think over a known-to-be-compromised , every day. Also Correlation based attacks are not the only Tor flaw.
- rank0 5y agoIt’s just my opinion on OPs argument. It’s quite a stretch to say that tor is compromised. The network is actively attacked sure. Nation states and sophisticated groups may be able to deanonymize users of high interest. A single vpn provider would be way lower hanging fruit to powerful adversaries. There’s a reason high profile criminal groups are able to operate over tor. When they DO get caught, it’s usually through some other unrelated opsec blunder. I use tor, ProtonVPN, and mullvad in addition to self managed wire guard instances. There’s no reason to be binary and you should use the tools which fit your use case.
- xvector 5y ago> It’s quite a stretch to say that tor is compromised. 1 in 300 connections were deanonymized at many points throughout this year. For any given trustworthy VPN, 0 connections were deanonymized this year. A truly trustworthy VPN is more trustworthy than Tor.
