Not Sure about the Dark Web?
A few years ago, the US Government launched a new computer network which became known as the Deep Web, a massive portion of the Internet that is unindexed by typical search engines like Google etc. This was initially used by academic institutions and governments to house sensitive information but over the years, individuals started to use it within their criminal elements and it became known as the Dark Web.
The Dark Web includes content that exists on 'darknets' - overlay networks that use the Internet but require specific encrypted software, configurations or authorization to access content. The dark web forms a part of the deep web, the part of the Web not indexed by web search engines.
A 'darknet' market is a commercial website on the dark web that functions primarily as a black market, selling or brokering transactions involving illicit drugs, cyber arms, weapons, counterfeit currency, stolen credit card details, forged documents, fake pharmaceuticals, steroids and stolen Username/Password login Details for private or corporate users.
Major breaches from large organizations like Yahoo (3million users); Uber (57million users); Equifax Credit (145million Users); AdultFriendFinder (412million users) and virtually all the social media websites like Facebook, Instagram, LinkedIn, Snapchat have been breached and are the data source for stolen credentials (Username/Passwords) that appear on the Dark Web.
