Criminal Marketplaces

Criminal marketplaces offer sellers and buyers a small amount of protection by letting them use anonymous transactions and exchange services. Escrow services and trust markers, which we use in real-world marketplaces like eBay, have been added to criminal markets so that the seller and buyer can rate each other’s services. The cybercrime markets thrive because the dark web’s criminal marketplaces offer both anonymity and a good way to get what you want. Even though these criminal marketplaces seem like the perfect place to do business, they are watched by law enforcement agencies that want to catch the criminals, white-hat hackers that want to find out who is involved, and black-hat hackers that want to destroy competitors and steal the money from the criminals.

By finding out what is for sale on the black market, the defender can figure out what they need to protect and how they should protect it. Do you store information about credit cards at rest in your business? Is the information about the credit card encrypted or not? If you have a data breach, is it likely that your organization’s data will end up on a black market with a “for sale” sign?

Tor

Tor, which stands for “The Onion Router,” is a network that hides the source of web traffic so that browsing the web is truly private. The Tor Browser hides your IP address and what you do on the Internet by sending your web traffic through a series of routers called “nodes.” Tor is used by whistleblowers, journalists, and other people who want to protect their privacy online because it hides what you do online and stops people from following you.

Tor makes web traffic anonymous by using a special encryption method that was first made by the US Navy to help protect communications between US intelligence agencies. Today, Tor is an open-source platform for privacy that anyone can use. Even though some countries, like China, have completely banned its use.

Along with a web browser, Tor also offers onion services through its onion network. These services help websites and servers stay anonymous. An onion web address, which can only be reached through the Tor Browser, hides both the website’s and visitors’ identities.

Tor is often used to make and get to the dark web because it has a complicated, encrypted connection that keeps both hosts and visitors anonymous. So, Tor is the perfect example of a browser for the dark web.

How does Tor, the browser for the “dark web,” work?

Tor encrypts and reroutes web traffic through its onion network by using onion routeing. After your information has been encrypted in multiple layers, it is sent through a series of network nodes called onion routers. Each router (or node) “peels away” a layer of encryption until the data is fully decrypted at its final destination.

The Tor circuit is made up of three layers of international proxies that work together to send encrypted data in an anonymous way. Let’s look at the three layers of network nodes in more detail:

Entry/Guard node: First, Tor Browser connects at random to an entry node that is known to the public. The entry node is where your data gets added to the Tor network.

Middle notes: All of your information is encrypted here. Then it goes through a series of nodes that decrypt your data one layer at a time. To protect privacy, each middle node only knows the names of the middle nodes that came before and after it.

Exit node: Once the last layer of encryption is removed, the decrypted data leaves the Tor network through an exit node and goes to its final server destination.
