Dropbox the famous cloud storage service has confirmed the security breach just now and only few accounts passwords were leaked online. Also an employee account who had a file that contains email addresses of users also accessed by the hackers. If you are using Dropbox to store your files then its time to change the password as Dropbox has confirmed, that it has took some steps to tighten up the security that prevents further attempts.
To improve and add more security, dropbox is going to bring two factor authentication to all the accounts. Whatever, this clearly shows that dropbox really handled the security practice at worst.
