The term "dark web" signifies a part of the internet that is not indexed by traditional search engines, requiring specific software to access, such as Tor. It consists of encrypted networks where users can maintain their anonymity. While some aspects of the dark web are used for legitimate purposes, such as promoting free speech in oppressive regimes, it is often associated with illegal activities, including substance trafficking, illegal marketplaces, and cybercrime. Accessing the dark web involves a higher risk due to potential exposure to cybersecurity threats and illegal content.
