IT Security: Hacker puts up 167 million LinkedIn passwords for sale

Email addresses and passwords for over 100 million LinkedIn members have been put up for sale on the Darknet by the same hacker who stole the data from the site in 2012.

LinkedIn has admitted that the 2012 hack was significantly worse than previously thought since the new data dump emerged.

The company has advised all members to change their passwords as they take steps to contact members whose data has been compromised and invalidate the passwords of affected accounts.

Hackers gained access to the site in 2012 and posted 6.5 million encrypted passwords on a Russian hacker forum, but email addresses were not included in that dump.

The passwords from both releases were encrypted with “no salt”, making them easier to crack. A salt is a random number that is needed to access encrypted data, along with a password.

The hacker who released the data goes by the name of Peace. He is selling the information on a Darknet marketplace called The Real Deal for 5 bitcoin (around $2,200).

A $5 million lawsuit was filed against Linkedin in the wake of the 2012 hack, blaming the company for its outdated security measures.

LinkedIn reminded users in its Wednesday statement that it now salts every password and urged members to use two-factor authentication.
