What is Dark web?
Websites reachable only through anonymity networks such as Tor, used for privacy and also hosting criminal markets, forums and leak sites.
The dark web is the part of the internet reachable only through anonymity networks such as Tor, with addresses ending in .onion. It hosts privacy tools, whistleblowing platforms and news mirrors as well as criminal markets, forums and ransomware leak sites.
Much of today's cybercrime trade has moved to ordinary forums on the open web and to Telegram, so "dark web monitoring" usually covers those too. Access needs careful operational security.
