Hacker advertises details of 117 million LinkedIn users on darknet

List of user IDs and passwords, allegedly sourced from cyber-attack in 2012, put on sale for around 1,500 as site says it is taking action

A hacker claiming to have the log in details of millions of LinkedIn users is advertising the data for sale online.

The extensive list of user IDs and passwords, which were allegedly sourced from a cyber attack on the networking site four years ago, is being advertised on the darknet - a sub-section of the internet not accessible through normal web browsers and often a platform for illegal activity.
