From LinkedIn on the data breach:
You may have heard reports recently about a
security issue involving LinkedIn. We would like to make sure you have the
facts about what happened, what information was involved, and the steps we are
taking to help protect you.
What Happened?
On May 17, 2016, we became aware that data stolen
from LinkedIn in 2012 was being made available online. This was not a new
security breach or hack. We took immediate steps to invalidate the passwords of
all LinkedIn accounts that we believed might be at risk. These were accounts
created prior to the 2012 breach that had not reset their passwords since that
breach.
What Information Was Involved?
Member email addresses, hashed passwords, and
LinkedIn member IDs (an internal identifier LinkedIn assigns to each member
profile) from 2012.
What We Are Doing
We invalidated passwords of all LinkedIn accounts
created prior to the 2012 breach that had not reset their passwords since that
breach. In addition, we are using automated tools to attempt to identify and
block any suspicious activity that might occur on LinkedIn accounts. We are
also actively engaging with law enforcement authorities.
LinkedIn has taken significant steps to strengthen
account security since 2012. For example, we now use salted hashes to store
passwords and enable additional account security by offering our members the
option to use two-step verification.
What You Can Do
We have several dedicated teams working diligently
to ensure that the information members entrust to LinkedIn remains secure.
While we do all we can, we always suggest that our members visit our Safety
Center to learn about enabling two-step verification, and implementing strong
passwords in order to keep their accounts as safe as possible. We recommend
that you regularly change your LinkedIn password and if you use the same or
similar passwords on other online services, we recommend you set new passwords
on those accounts as well.
