A update from a couple of days ago on the Raptr website warns users to change their passwords (passwrds?) due to a breach (thanks Mashiki). Here's word from CEO Dennis "Thresh" Fong:

User names, email addresses, password hashes, and some first and last names may have been accessed. This means that although the passwords are hashed, users with weak passwords are vulnerable to unauthorized access. It's important to note that our two-factor authentication system used for redeeming Raptr Reward Points ensures that even if your Raptr account was among those compromised, the points you've earned as a Raptr member are protected.

Although the potential risk to Raptr users is pretty minimal, we urge you to access any accounts on other sites and services in which you use the same login and password associated with your Raptr account and change the related password(s) immediately.
