Twitch.tv Breached (email from Twitch)

A more specific email appears to have been sent to affected users. It seems to imply that malicious code was inserted into the login page, but doesn't provide any further details to the extent of the compromise.

From my email:

We are writing to let you know that there may have been unauthorized access to some of your Twitch user account information, including possibly your Twitch username and associated email address, your password (which was cryptographically protected), the last IP address you logged in from, and any of the following if you provided it to us: first and last name, phone number, address, and date of birth.

For your protection, we have expired your password and stream keys. In addition, if you had connected your account to Twitter or YouTube, we have terminated this connection.

You will be prompted to create a new password the next time you attempt to log into your Twitch account. If applicable, you will also need to re-connect your account to Twitter and YouTube, and re-authenticate through Facebook, once you change your password. We also recommend that you change your password at any other website where you use the same or a similar password.

We apologize for this inconvenience.

The Twitch Team
