LinkedIn User? Your Data May Be Up For Sale (zdnet.com)

An anonymous reader cites a ZDNet report: Reports indicate that a LinkedIn data breach may have led to the sale of sensitive data belonging to 117 million users. The company's website experienced a data breach in 2012, but the true consequences of the breach are only now becoming apparent. Users of LinkedIn's website in 2012 discovered that roughly 6.5 million user account passwords were posted online, and the company never completely confirmed just who was impacted by the security incident. However, a hacker called "Peace" told the publication that this information is being sold on the dark web for roughly $2,200, and paid hacker data search engine LeakedSource also claims to have the data. Both sources say there are approximately 167 million accounts in the data dump, 117 million of which have both emails and encrypted passwords.LinkedIn has acknowledged the breach. In a blog post, the company writes: Yesterday, we became aware of an additional set of data that had just been released that claims to be email and hashed password combinations of more than 100 million LinkedIn members from that same theft in 2012. We are taking immediate steps to invalidate the passwords of the accounts impacted, and we will contact those members to reset their passwords. We have no indication that this is as a result of a new security breach.

If they had salted their passwords, even if the attackers managed to learn the salt value they would still have to generate a whole custom rainbow table just for that password table.
