Hackers are said to have obtained thousands of login details for Uber accounts worldwide - and are selling them for as little as $ 1 on the dark web . Two sellers - known only as Courvoisier and ThinkingForward - are using online marketplaces such as AlphaBay to offer this personal information . The compromised accounts were discovered by Motherboard 's Joseph Cox who was sent a sample list of accounts . He confirmed that the details being sold were both valid and linked to live accounts .

' The dark net is a subsection of the deep web - the part of the internet that does not show up in searches or on social media . Most of the information on the web is far down on dynamically generated sites , unable to be found or seen by traditional search engines . The dark net is used as a way of sharing information and trading goods , but the anonymous and encrypted nature of it has attracted large amounts of illegal activity . The Silk Road website , and its successor that were recently shut down , was used to sell drugs in exchange for Bitcoins . Other dark net sites let users share pornographic photographs , hacked information and credit card numbers . The Silk Road used an underground computer network known as the The Onion Router ( TOR ) , which is a matrix of encrypted websites and servers that disguise the identity of users . It uses numerous layers of security and encryption , hiding the IP address and the activity of the user . Full credit card details are not stored on the account , but a hacker can see the last four digits of a card number , as well as their full email address and phone number . From this a person could commit wider identity fraud , or sign into other accounts if the username and password is copied across other sites , apps and accounts . Courvoisier told Mr Cox they have 'thousands ' of login details obtained from 'hacked accounts ' and sells them for $ 1 each . ThinkingForward sells them for $ 5 and gives a discount on bulk purchases . These are said to be just two examples of 'dozens ' of listings on the dark net .
