How to Create Anonymous Website(Dark Net)

Tor is an anonymous, secure network that allows anyone to access websites with anonymity. People normally use Tor to access normal websites, but they don’t have to. If you want to set up your own anonymous website, you can create a hidden service Tor site. Your hidden service website runs entirely within Tor, so no one will know who created and runs the website. Only people using Tor can access it, though. Hidden service Tor sites are ideal for anyone who wants to set up a website anonymously, such as political activists in repressive countries.

Not all hidden services have to be websites. You could create an SSH server, IRC server, or any other type of server and offer it as a hidden service on Tor. This tutorial will focus on setting up a hidden Tor site using the Savant web server – which Tor recommends – on Windows. The steps can also be applied to other operating systems and web servers.

Step 1: Install Tor

To get started, you’ll have to download and install Tor on your computer. If you already have it installed, you can skip this step. By default, Tor installs the Tor browser bundle, which includes a specially configured Firefox browser.

You’ll see a green onion icon in your system tray when you’re connected to the Tor network.

Once it’s installed, you can check out an example hidden service by pluggingduskgytldkxiuqc6.onion into your Tor web browser’s address bar.

Tor must always be running on your system for the hidden service to be accessible. If your computer is off, disconnected from the Internet, or if Tor isn’t running, the hidden service Tor side won’t be accessible. This does have some anonymity implications – it’s theoretically possible to infer whether or not your computer is running the hidden service by seeing whether it’s accessible when your computer is off.

Step 2: Install & Configure A Web Server

You’ll need a web server to serve the hidden service site from your system. Tor’s official documentation recommends against using the common Apache web server. Instead, Tor recommends using the Savant web server on Windows or thethttpd Web server on Mac OS X, Linux and other UNIX-like operating systems. Tor’s documentation notes that Apache “[is] big and has lots of places where it might reveal your IP address or other identifying information, for example in 404 pages” but also notes that “Savant probably has these problems too“.

The takeaway is that web server configuration is very important. If you’re running a very sensitive hidden Tor site, you’ll want to go through your web server’s settings and ensure it isn’t leaking any information that could be used to identify you, such as your IP address.

We’ll use Savant as an example here, but you can set the same options in other web servers. To configure Savant, launch its main window and click the Configuration button.

From the configuration window, you’ll need to set the “Server DNS Entry” box to “localhost” to bind Savant to localhost. This ensures your website is only accessible from your local computer, so people can’t access it over the normal Web and see you’re hosting the hidden service Tor site.

You’ll also have to note the port number you’re using.

After the web server is configured, you’ll want to add your content. By default, Savant uses the C:\Savant\Root directory (you can change this from the Pathstab). Ensure you replace the index.html file in this directory with the file you want as your homepage.

You can verify it works by typing localhost into your main browser’s address bar. If you set a different port instead of 80 – say, port 1000 – type localhost:1000instead.

Step 3: Configure The Hidden Service

Now that Tor’s installed and a web server is running, all you have to do is tell Tor about it. You should be able to add this information to the torrc file through the Vidalia graphical user interface, but I experienced errors and had to do this by hand.

First, shut down Tor if it’s running.

Next, locate your torrc file. If you installed the Tor Browser Bundle, you’ll find it in the Tor Browser\Data\Tor directory. Open this file with Notepad or another text editor.

Add the following section to the end of the file:

1 2 3

<em># Hidden Service</em> <em>HiddenServiceDir C:\Users\Name\tor_service</em> <em>HiddenServicePort 80 127.0.0.1:80</em>

Replace C:\Users\Name\tor_service with the path to a directory Tor can read and write to on your system. Do not use the directory that already contains your website. This should be an empty directory.

Replace the :80 with the port the web server is using on your system. For example, if the web server is running on port 5000, you’d use the line HiddenServicePort 80 127.0.0.1:5000.

Save the file after editing it. You’ll also have to create the directory you specified, if it doesn’t already exist.

Restart Tor after you do this. Once you have, you’ll want to check the Message Log to see if there are any error messages.

If the Message log is free of errors, you’re good to go. Check out the hidden service directory you created. Tor will have created two files in the directory – hostname and private_key. Don’t give anyone the private_key file or they’ll be able to impersonate your hidden service Tor site.

You’ll want to open the hostname file in Notepad or another text editor. It will tell you the address of your new hidden service Tor site. Plug this address into your Tor web browser and you’ll see your website. Give the address to others so they can access your site. Remember, people must be using Tor to access your hidden service site.

Everything About Tor: What is Tor? How Tor Works ?

Tor or The Onion Router, allows anonymous use of internet veiling the actual identity of the user. It protects the user from any traffic analysis and network spying. Tor is perhaps the most popular and secure option available for anonymous internet connectivity.

Where it came from?

Tor is based on the principle of ‘onion routing’ which was developed by Paul Syverson, Michael G. Reed and David Goldschlag at the United States Naval Research Laboratory in the 1990’s. The alpha version of Tor named ‘The Onion Routing Project’ or simply TOR Project was developed by Roger Dingledine and Nick Mathewson, launched on September 20, 2002. Further development was carried under the financial roof of Electronic Frontier Foundation (EFF).

The Tor Project Inc. is a non-profit organisation that currently maintains Tor and is responsible for its development. It is mainly funded by the United States Government, further aid is provided by Swedish Government and different NGOs & individual sponsors.

How it Works?

Tor works on the concept of ‘onion routing’ method in which the user data is first encrypted, and then transferred through different relays present in the Tor network, thus creating a multi-layered encryption (layers like an onion), thereby keeping the identity of the user safe. At each relay, one layer is decrypted and the remaining data is forwarded to any random relay until it reaches its destination server. For the destination server, the last Tor node/exit relay appears as the origin of the data. It is thus very difficult to trace the identity of user or the server by any surveillance systems acting in the mid-way.

Other than providing anonymity to standalone users, Tor can also provide anonymity to websites and servers this comes under the category of hidden services. Also, P2P applications like Bittorrent can be configured to use tor network and download torrent files.

Controversies and Influence:

Tor has been eulogized for the anonymity and privacy it provides to the users who want to bypass censorship, who are abused and traumatized by stalkers and social activists who are afraid of being arrested by the authorities. It has been used by different security agencies to share confidential information.

The NSA whistle-blower Edward Snowden used Tor to leak information about PRISM to The Guardian and The Washington Post.

Tor has been criticized for the reason that it acts as a medium for different illegal activities like data breaching, drug dealing, gambling etc. Tor is also used by malevolent people to communicate over the internet while keeping their identity hidden which makes it difficult for the security agencies to trace them.

The U.S. National Security Agency (NSA) has called Tor “the king of high-secure, low-latency Internet anonymity” and similar comments by BusinessWeek magazine, “perhaps the most effective means of defeating the online surveillance efforts of intelligence agencies around the world”.

Another speculation made is that Tor takes its funding from the U.S. Government which may lead to the assumption that NSA may have compromised the identities of individual Tor users, but the executive director Andrew Lewman has disclaimed any confederations with NSA.

Can it be Compromised?

Various claims have been made to compromise Tor’s anonymity and security from time to time. The most famous is the Bad Apple Attack in which the researchers claimed to have identified around 10k IP addresses of active Bittorrent users who were connected via Tor.

Another famous compromise was done by the Heartbleed bug in April 2014 which halted Tor network for several days.

Traffic Fingerprinting is a method used to analyse web traffic by analysing the patterns, responses and packets in a particular direction. This can be used to attack the Tor network by making the attacker’s computer act as the guard.
The main vulnerability found is at its exit points where the level of security is very low as compared to the rest of the Tor network.

Products based on Tor:

The Tor Project Inc. has released Tor Browser which is a modification of an Extended Support Release version of Mozilla Firefox browser. The browser is made portable so that it be used from an external media and reduces the hazel of installation. It removes the user history after every use, thus reducing the risk of any kind of cookie tracking.

Other products like Orbot – an android version of Tor, Orfox – a mobile version of Tor Browser are developed by The Guardian Project which is a global developer community founded by Nathan Freitas.

We can set-up SOCKS (Socket Secure) based applications to use the Tor network by configuring them with loop-back address.

Tor Alternatives:

Hornet is a new anonymity network that provides higher network speeds compared to Tor. I2P, Tails, SubgraphOS, Freenet and Freepto are other top alternatives that can be used.

Winding Up:

Tor has proved to be a great medium for safe, secure and anonymous web presence that can be provided to a user at no cost. Although it is available for a positive intention, but is also used by malignant people in fulfilling their needs. The Tor project has led to an optimistic approach towards censorship and surveillance free internet.

These Four Lines Of Code Can Crash Anyone’s Smartphone And Computer

There’s a notorious link being shared on social networking websites that can crash nearly all smartphones — all you have to do is just click on this link. Known as crashsafari.com(clicking on this will crash your browser), this link crashes your browser by overloading it with thousands of characters in the address bar each second. As a result, the phone memory exhausts and your device crashes.

Back in September, we encountered a  similar bug in Google Chrome that caused the browser to crash with just 16 characters. This website link is being spread via apps, social networks, simple URLs, and shortened URLs. It should be noted that this bug isn’t malicious and it doesn’t break anything in your phone.

Devices affected by Crashsafari.com:

The bug hits iPhone’s Safari browser in the worst manner possible. If you click on the link, it crashes your iPhone 6S or iPhone 5S running iOS version 9.2.1 or a regular iPhone 6 running iOS 9.2. After about 20 seconds, it’ll force the iPhone to reboot and heat up the device.

Even though the new bug is called crashsafari, it affects Android phones and Google Chrome as well. Apart from phones, this bug also affects desktop browsers if your computer doesn’t have enough RAM and CPU power.

How does Crashsafari.com work?

The website is running a small piece of JavaScript that creates a loop with the help of History API and crashes your device. The History API allows the websites to change the URL of the page without performing page refresh.

If you are an iPhone user, you should be very careful about any new incoming shortened links as they could forcibly reboot your phones. Notably, these links have already been opened 100,000 times. You are advised to take extra care as it’s being spread on the web via misleading links.
