If you use LinkedIn (or have in the past, and never cancelled your account), change your passwords to be secure.

Please make sure your password for Linkedn is unique; and go to the LinkedIn account settings page directly (do not use a ink from an email or another web page).

The latest tweet from LinkedIN is as follows

“Our team continues to investigate, but at this time, we’re still unable to confirm that any security breach has occurred. Stay tuned here.”

Even so, play safe, and change your password to be unique (not used with any other site or resource), and secure.
