The Deep Web is a part of the internet that is not accessible through regular search engines and web browsers. It is estimated to be over 500 times larger than the surface web, which is the part of the internet that can be accessed through search engines. The Deep Web is home to many illegal activities, such as drug dealing, money laundering, identity theft, and the sale of stolen or falsified documents.

One of the most common types of illegal activity on the Deep Web is the sale of illicit drugs. Drug dealers can easily set up shop on the Deep Web and use it to distribute their product anonymously. The Dark Web, which is a subset of the Deep Web, is home to a variety of illegal markets where drugs, stolen goods, and other contraband can be purchased.

Another type of illegal activity on the Deep Web is money laundering. Criminals can use the anonymity of the Deep Web to transfer funds without leaving any trace of their activity. Money launderers often use virtual currencies, such as Bitcoin, to transfer funds and hide their identity.

Finally, the Deep Web is also home to a variety of scams, frauds, and other criminal activities. Cybercriminals use the anonymity of the Deep Web to buy and sell stolen data, such as credit card numbers or personal information. They also use it to distribute malware and launch phishing attacks.
