6,458,020 LinkedIn user accounts was breached a few days ago. A list of just under 6,4 million users sha-1 password hashes was posted to a Russian underground website.
LinkedIn has not yet confirmed how many accounts are involved but has admitted that there has been a security breach.
eHarmony, a popular dating site with around 20 million users, has also reported a security breach.
It is suspected that hackers are trying to create a list of users that re-use the same or similar passwords in order to commit mass bank robberies, fraud, Internet drive by attacks and identity theft.
