If you have a Linkedin account, just change your password as 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), according to Motherboard.
The search engine LeakedSource, which sells hacked data, also claims to have obtained the contents of the data dump, and asks affected users to contact them if they wish to be removed from their list.
