2012 LinkedIn Security Breach Strikes Again

A 2012 security breach that revealed the passwords of LinkedIn members is rearing its ugly head again.

A 2012 security breach that revealed the passwords of LinkedIn members is rearing its ugly head again.

Chief information security officer Cory Scott announced in a blog post that the email and hashed password combinations of more than 100 million users obtained in the 2012 breach were released, writing:

In 2012, LinkedIn was the victim of an unauthorized access and disclosure of some members’ passwords. At the time, our immediate response included a mandatory password reset for all accounts we believed were compromised as a result of the unauthorized disclosure. Additionally, we advised all members of LinkedIn to change their passwords as a matter of best practice.

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.

We take the safety and security of our members’ accounts seriously. For several years, we have hashed and salted every password in our database, and we have offered protection tools such as email challenges and dual-factor authentication. We encourage our members to visit our safety center to learn about enabling two-step verification, and to use strong passwords in order to keep their accounts as safe as possible.
