Egerstad also suggests Tor nodes may be controlled by powerful agencies governments with vast resources:. From the Tor Project blog :. Over the last few days, we received and read reports saying that several Tor relays were seized by government officials. We do not know why the systems were seized, nor do we know anything about the methods of investigation which were used.

Specifically, there are reports that three systems of Torservers. Commenting on this case, ARS Technica noted in On July 4, the Tor Project identified a group of Tor relays that were actively trying to break the anonymity of users by making changes to the Tor protocol headers associated with their traffic over the network. The rogue relays were set up on January 30, —just two weeks after Blake Benthall allegedly announced he had taken control of Silk Road 2.

This issue continues to gain attention. In this Gizmodo article from , we find the same problems. Bad actors can and do operate Tor nodes. Additional reading: A mysterious threat actor is running hundreds of malicious Tor relays. The fundamental issue here is there is no real quality control mechanism for vetting Tor relay operators. Not only is there no authentication mechanism for setting up relays, but the operators themselves can also remain anonymous.

Assuming that some Tor nodes are data collection tools , it would also be safe to assume that many different governments are involved in data collection, such as the Chinese, Russian, and US governments. See also: Tor network exit nodes found to be sniffing passing traffic. Over the last decade privacy infrastructures such as Tor proved to be very successful and widely used. However, Tor remains a practical system with a variety of limitations and open to abuse.

Particularly the privacy of the hidden services is dependent on the honest operation of Hidden Services Directories HSDirs. In this work we introduce, the concept of honey onions HOnions , a framework to detect and identify misbehaving and snooping HSDirs. After the deployment of our system and based on our experimental results during the period of 72 days, we detect and identify at least such snooping relays. Furthermore, we reveal that more than half of them were hosted on cloud infrastructure and delayed the use of the learned information to prevent easy traceback.

Just a few months after the HSDir issue broke, a different researcher identified a malicious Tor node injecting malware into file downloads. According to ITProPortal :. Authorities are advising all users of the Tor network to check their computers for malware after it emerged that a Russian hacker has been using the network to spread a powerful virus.

The malware is spread by a compromised node in the Tor network. Due to the altered node, any Windows executable downloaded over the network was wrapped in malware , and worryingly even files downloaded over Windows Update were affected. Another interesting case highlighting the flaws of Tor comes form when the FBI was able to infiltrate Tor to bust another pedophile group. According to Tech Times :. The U.

Senior U. The ruling by the district judge relates to FBI sting called Operation Pacifier, which targeted a child pornography site called PlayPen on the Dark web. The accused used Tor to access these websites. The federal agency, with the help of hacking tools on computers in Greece, Denmark, Chile and the U. This essentially opens the door to any US government agency being able to spy on Tor users without obtaining a warrant or going through any legal channels.

This, of course, is a serious concern when you consider that journalists, activists, and whistleblowers are encouraged to use Tor to hide from government agencies and mass surveillance. The quote below, from the co-founder of Tor, speaks volumes. I forgot to mention earlier, probably something that will make you look at me in a new light.

I contract for the United States Government to build anonymity technology for them and deploy it. They think of it as security technology. This quote alone should convince any rational person to never use the Tor network, unless of course you want to be rubbing shoulders with government spooks on the Dark Web. This three-person team, working for the US government, developed Tor into what it is today. The quote above was taken from a speech by Roger Dingledine, which you can also listen to here.

After Tor was developed and released for public use, it was eventually spun off as its own non-profit organization, with guidance coming from the Electronic Frontier Foundation EFF :. At the very end of , with Tor technology finally ready for deployment, the US Navy cut most of its Tor funding, released it under an open source license and, oddly, the project was handed over to the Electronic Frontier Foundation.

Some journalists have closely examined the financial relationship between Tor and the US government:. But I crunched the numbers and found that the exact opposite was true: In any given year, Tor drew between 90 to percent of its budget via contracts and grants coming from three military-intel branches of the federal government: the Pentagon, the State Department and an old school CIA spinoff organization called the BBG. It was a military contractor.

It even had its own official military contractor reference number from the government. We are now actively looking for new contracts and funding. Sponsors of Tor get personal attention, better support, publicity if they want it , and get to influence the direction of our research and development!

There you have it. Tor claims donors influence the direction of research and development — a fact that the Tor team even admits. Do you really think the US government would invest millions of dollars into a tool that stifled its power? So you need to have other people using the network so they blend together.

When you use Tor, you are literally helping the US government. Your traffic helps to conceal CIA agents who are also using Tor, as Dingledine and journalists are pointing out. Tor is fundamentally a tool for the US government , and it remains so today:.

You will never hear Tor promoters discuss how important it is for the US government to get others on the the Tor network. This remains a taboo topic that Tor advocates simply avoid. A branch of the U. Navy uses Tor for open source intelligence gathering, and one of its teams used Tor while deployed in the Middle East recently. Law enforcement uses Tor for visiting or surveilling web sites without leaving government IP addresses in their web logs, and for security during sting operations.

Michael Reed, another early developer of Tor, explained how it has always been a tool for US government military and intelligence operations :. Not helping dissidents in repressive countries. Not assisting criminals in covering their electronic tracks.

Not giving a 10 year old a way to bypass an anti-porn filter. Of course, we knew those would be other unavoidable uses for the technology, but that was immaterial to the problem at hand we were trying to solve and if those uses were going to give us more cover traffic to better hide what we wanted to use the network for, all the better …I once told a flag officer that much to his chagrin.

Just as Roger Dingledine asserted in the opening quote to this section, Paul Syverson Tor co-founder also emphasized the importance of getting other people to use Tor, thereby helping government agents perform their work and not stand out as the only Tor users :. You need to have a network that carries traffic for other people as well. Tor is branded by many different individuals and groups as a grassroots project to protect people from government surveillance.

Tor was created not to protect the public from government surveillance, but rather, to cloak the online identity of intelligence agents as they snooped on areas of interest. But in order to do that, Tor had to be released to the public and used by as diverse a group of people as possible: activists, dissidents, journalists, paranoiacs, kiddie porn scum, criminals and even would-be terrorists — the bigger and weirder the crowd, the easier it would be for agents to mix in and hide in plain sight.

According to these Tor developers and co-founders, when you use Tor you are helping US government agents in doing whatever they do on the Tor network. Why would anyone who advocates for privacy and human rights want to do that? Another recurring problem with Tor is IP address leaks — a serious issue that will de-anonymize Tor users, even if the leak is brief. This issue illustrates a larger problem with Tor: it only encrypts traffic through the Tor browser , thereby leaving all other non-Tor browser traffic exposed.

Unlike a VPN that encrypts all traffic on your operating system, the Tor network only works through a browser configured for Tor. This design leaves Tor users vulnerable to leaks which will expose their identity in many different situations:. Therefore blame does not lie with Tor itself, but rather with people not using Tor correctly. Dan Eggerstad emphasized this issue as well when he stated :.

Once again, non-technical users would be better off using a good VPN service that provides system-wide traffic encryption and an effective kill switch to block all traffic if the VPN connection drops. As we saw above with the bomb threat hoax, Eldo Kim was targeted because he was on the Tor network when the bomb threat was sent. Other security experts also warn about Tor users being targeted merely for using Tor.

In addition, most really repressive places actually look for Tor and target those people. There is no cover. This is assuming it is being used to evade even in a country incapable of breaking Tor anonymity. Given that Tor is compromised and bad actors can see the real IP address of Tor users, it would be wise to take extra precautions. This includes hiding your real IP address before accessing the Tor network. With this setup, even if a malicious actor was running a Tor server and logging all connecting IP addresses, your real IP address would remain hidden behind the VPN server assuming you are using a good VPN with no leaks.

You can sign up for a VPN with a secure anonymous email account not connected to your identity. For the truly paranoid, you can also pay with Bitcoin or any other anonymous payment method. Most VPNs do not require any name for registration, only a valid email address for account credentials. Using a VPN in a safe offshore jurisdiction outside the 14 Eyes may also be good, depending on your threat model.

This is discussed more in my guide on multi-hop VPN services. When you chain VPNs , you can distribute trust across different VPN services and different jurisdictions around the world, all paid for anonymously and not linked to your identity. With Tor alone, you put all your trust in The Onion Router….

There are other attacks that the Tor Project admits will de-anonymize Tor users archived :. As mentioned above, it is possible for an observer who can view both you and either the destination website or your Tor exit node to correlate timings of your traffic as it enters the Tor network and also as it exits.

Tor does not defend against such a threat model. Once again, a VPN can help to mitigate the risk of de-anonymization by hiding your source IP address before accessing the guard node in the Tor circuit. Can exit nodes eavesdrop on communications? From the Tor Project:.

Yes, the guy running the exit node can read the bytes that come in and out there. Tor anonymizes the origin of your traffic, and it makes sure to encrypt everything inside the Tor network, but it does not magically encrypt all traffic throughout the Internet.

However, a VPN can not do anything about a bad Tor exit node eavesdropping on your traffic, although it will help hide who you are but your traffic can also give you away. I discuss these points more in my VPN vs Tor comparison. All privacy tools come with pros and cons. Selecting the best tool for the job all boils down to your threat model and unique needs.

This is pathetic. A VPN will offer system-wide encryption, much faster speeds, and user-friendly clients for various devices and operating systems. Additionally, VPNs are more mainstream and there are many legitimate and legal!

For those who still want to access the Tor network, doing so through a reliable VPN service will add an extra layer of protection while hiding your real IP address. Tor network exit nodes found to be sniffing passing traffic. Sven Taylor is the founder of RestorePrivacy. With a passion for digital privacy and online freedom, he created this website to provide you with honest, useful, and up-to-date information about online privacy, security, and related topics. His focus is on privacy research, writing guides, testing privacy tools, and website admin.

Most were from Europe, with several Oxford grads who wrote compilers for Borland, two from the US and one from Australia. When interviewed, they led me around and showed me a large data center in the building and I noticed the provider was Southern Bell.

I asked and they said they use so much bandwidth the phone company decided to just move the central office of the area there. They made a peculiar comment that they liked it that I was a military pilot and they liked pilots, which also made no sense.

I saw three guys dumping traffic and asked what they were doing. It would be like watching paint dry for me. While the guy courting me was very wealthy, he was not this wealthy. I had a great job as CIO of a Tier-1 Automotive supplier, paid well, great family area, could do what I wanted, set my own hours, and I had weekends off except during major upgrades of my own doing.

I refused. Some time later, I started receiving peculiar phone calls from attorneys asking me vague questions and insisting I knew a lot more than I did. I relayed that to the guy who wanted me to work with them and I never heard from him again.

He had closer ties personally with the guys but was not one of us. I also learned that they perform drone strikes from down there, which might be why the strange comment about me having been a military pilot. The story from him was the peculiar calls were because the guy in charge turned out to be a crook. Of the guys hired, the guy from Australia and the girl from Germany found out their goals were the same and both left.

They got married and still got to stay in the US and are now citizens. As I recall from the last conversation, baby 11 was on the way, and they were homeschooling. They both work as contractors for the guy telling me all of this stuff. The remainder immediately ended up at LexisNexis, which is noteworthy, because if you need an accident report, this is where the police send you, and is the brain child of the guy I would have been working for.

I know the character of the one who left with the girl from Germany and another in the group who was also a pastor, which might make sense of the move to LexisNexis. On the other hand, when Snowden was hired, he would have had to have been sworn to secrecy before knowing the scope of what it entailed.

The verdict of what he did afterward can swap in your mind daily. I picked a far away country and determined it was actually exiting a server in New York. I published several places on YouTube how to duplicate what I had done and it is deleted immediately. My concern is not that they are collecting everything, it is you cannot trust those entrusted to safeguard us and work for the good of its citizens.

Some examples are the IRS targeting certain groups by not only denying their rights, they gave their customer lists to their competition who are their supporters, and then pled the 5th. Then there was the Trump investigation fiasco where we saw attempted entrapment and obtaining telephone records with no warrant of any kind, which were never presented, so apparently worked against the narrative.

They are saying journalists and whistleblowers are enemies of the people. They have unfair advantages dealing with documents. They know the interior of my life with my psychologist. If people can so easily be identified when using Tor, why would any goverment agent use it? Thank you for writing this, Sven! Eye opening for me. I am confused. I log into some sort of. If the exit node is malicious, can it download a virus if I try to download a file on that site?

If so, why would anyone use tor for anything that involves logging into any website or involves confidential information, like financial documents or making cryptocurrency transactions? Sure, I would be anonymous, but would it not be highly insecure, even on a. Or am I missing something about how it works? Does the. If they can steal your data like that and log into any website you visit over tor, or if they can put a virus into any file you download, or if they can see private information, would it not be safer to use a vpn that you trust and has no logs, instead of a vpn over tor?

They will however see where the packets come from and where they go. At least on any website that is halfway decent secure. It is hashed in your browser and this hash is transported to the website and it compares it with what is stored in its database.

Very simple but effective. If your website you download from uses TLS https they cannot manipulate your download because it is encrypted. Furthermore, if you use a secure operating system like Linux, you would be far less at risk of getting malicious downloads.

Feds love it when you use their honeypot Tor project. If that is the case, then if TOR becomes widespread, it will effectively allow the US to monopolize the internet. Release TOR to the public for criminal use and for hiding dissidents in third world countries 2. We also worked really hard to make sure the UI text would make it easy for the user to understand what a bridge is for and how to configure to use one.

Another update was a little tip we added at the drop-down menu as you can see below for which bridge to use in countries that have very sophisticated censorship methods. The proxy settings at our Tor Launcher configuration wizard is an important feature for users who are under a network that demands such configuration. But it can also lead to a lot of confusion if the user has no idea what a proxy is.

Since it is a very important feature for users, we decided to keep it in the main configuration screen and introduced a help prompt with an explanation of when someone would need such configuration. We are also planning a series of improvements not only for the Tor Launcher flow but for the whole browser experience once you are connected to Tor including a new user onboarding flow. And last but not least we are streamlining both our mobile and desktop experience: Tor Browser 7.

Tor is a special web browser that anonymizes your internet traffic by sending it through multiple Tor computers. Tor browser makes it difficult for governments or websites to link your browsing activity to you and therefore enhances your privacy online. But is it safe to use Tor? Well, like any other system, it has its weaknesses.

Your system can still be hacked, you can still get malware when browsing with Tor — especially if you use it to access the dark web. Read the full article below for everything you need to know about staying safe while using Tor browser. For many, The Onion Router Tor has become a household name. So is Tor safe to use? Is it still a decent way to anonymously surf the web? The short answer is yes. You can use Tor browser to surf anonymously. However, we strongly discourage you from using just Tor for online protection.

Multiple incidents have shown that unsafe use of Tor can result in a severe privacy leak or even issues with your online safety. Think of viruses, criminals, and hacks. This article will shed some more light on these problems with Tor. This service has excellent encryption, is very user-friendly, and has thousands of servers available for you to choose from. Tor browser is a special browser that anonymizes your internet traffic. Your data is sent past multiple Tor computers.

In other words: Tor browser makes it a lot more difficult for websites and even governments to link your online browsing behavior back to you. At every stop or node that Tor uses to cloak your data, an extra layer of encryption is added or removed, depending on which way the traffic is going.

Therefore, using the Tor browser should result in a safe and anonymous internet experience. In these cases, Tor ensures freedom of speech. People using Tor still have the possibility to speak freely about political issues, without having to fear getting prosecuted for it. Simultaneously, there are also people that use the Tor browser out of principle. Several court cases have shown that illegal activities on the dark web can sometimes be traced back to specific individuals using Tor browser.

The NSA could clearly see who used those nodes. This was problematic for users who concern themselves with illegal practices. The moment those users are identifiable, the police can track them down and arrest them. Tor is no longer as safe as it once was. Many groups, organizations, and individuals want access to the information Tor browser is hiding and try to get that time and again.

In , one group of researchers succeeded. Financed by the government, they took a closer look at Tor browser and were able to collect information from the browser for months on end. Weaknesses in the Tor software can surface in less compromising ways, as well: in , users found a leak that could easily make IP addresses of Linux and macOS users visible. Like every other system, it has its weaknesses.

Even though leaks are constantly being patched, you can never be sure whether these patches happen in time. Aside from this, there are more reasons to be worried about the safety that Tor offers. Here are a few. First of all, Tor users are regularly hacked. This could happen to anyone, which means every user should be aware of it. A second danger is that you could still be tracked online, even when using Tor. Bad exit nodes are one example of how this could happen.

If the person who controls this node wants to, they could see all the traffic passing through it. If this happens — as was the case with the NSA — your internet data is no longer private. One thing worth mentioning is that you usually do stay anonymous in such a situation. Instead, they focus on uncovering illegal activities, some as horrifying as the spreading of child porn on the dark web.

Tor was initially built to allow for anonymous communication within the US Navy. Some people fear that the US Navy still has secret access to the traffic going through the browser. This is, however, not at all the case. An oddity, therefore, would be discovered and eliminated within moments. Before you tackle the internet with this browser, you should be aware of the dangers of the dark web.

Tor allows you to access this hidden part of the internet. The dark web is part of the much bigger deep web. The dark web is unregulated and, therefore, quite fascinating. Among other things, you could come across marketplaces for drugs, weapons, and illegal credit cards. Not every website on this dark part of the internet is as dodgy as this. Some pages allow people to speak their minds freely without having to fear prosecution from a dictatorial regime. The unregulated nature of the dark web results in a space that holds both the best and the worst of humanity.

Always be careful when you use Tor to visit the dark web. Try not to get caught up in websites that infect your computer with malware. Stay away from websites that concern themselves with illegal activities. Tor is the centerpiece of the internet safety niche. No other browser matches its security features and encryption abilities. But what safety tools does Tor offer exactly? The browser automatically applies the following out-of-the-box:. This is due to the tedious but necessary process whereby Tor connects to several circuits that contain relays, layers, proxies, nodes, servers, and bridges.

Simply put, an onion service is a website that can only be accessed through the Tor network. Tor Browser provides an option to prioritize onion services when available. Some websites you can access on a regular browser such as Mozilla Firefox or Google Chrome also have onion services. News websites like the New York Times and BBC News have onion services for people who may not be able to access their public websites because of government censorship.

The fewer website features Tor browser enables, the more secure your surfing session becomes. And last but not least we are streamlining both our mobile and desktop experience: Tor Browser 7. Tor Browser That includes everything from updating the fundamentals like color, typography and buttons to redrawing each of our icons to match the new thinner icon style. In addition to the browser chrome itself, the connection screen, circuit display, security levels and onion site errors all received a sprucing-up too — featuring some small but welcome quality of life improvements to each.
