LinkedIn Corp has released a blog post revealing that the 2012 data breach of its website was more extensive than previously thought. More than 100 million LinkedIn usernames and passwords were taken in the data theft and possibly available on hacker websites.
LinkedIn has reset passwords for all accounts created prior to the breach that haven’t been updated since 2012, and notified these users by email. They also recommend regularly changing passwords.
