Cloud note taking and organizing application Evernote has been the victim of a hacker attack. The company issued an advisory earlier today that nearly 50 million users may have had their usernames, email addresses and encrypted passwords stolen.

Evernote first became aware of the security breach on February 28th. At this time, it does not appear that banking or payment details have been leaked, and the hackers did not gain access to user notes stored on the system.

The passwords that were stolen were encrypted, making it less likely that the hackers would be able to find out what the true plain text passwords are.

The company sent an e-mail to users today (a portion is in the screenshot below) informing them that their passwords have been reset, and they would need to log in and change it to a new string. Passwords will need to be re-entered in all applications where users have installed Evernote, such as on their mobile devices and tablets.
