I had an alert over the weekend from the security website, haveibeenpwned.com If you're not signed up, I recommend it, and it notifies you when any of your personal data may be at risk.
It seems my email was part of the big hack attack earlier this year, along with the following info from LinkedIn:
Education levels, Email addresses, Genders, Geographic locations, Job titles, Names, Social media profiles
So strongly recommend anyone changes their password, and as usual, never use the same email/password combination on multiple sites.
