Hacker Group DerpTrolling Leaks Windows Live, PSN and 2K Games Usernames and Passwords

Along with the usernames and passwords, the group posted the following message:

Dear Internet, the following is a very small portion of Lord Gaben and the rest of his crews glorious raids across the high seas of the Internet.

Portions of our raids include:

2K Gaming studio user credentials
Windows Live Email user credentials
PlayStation Network user credentials

These usernames our bestowed upon you in the humble name of Derp.
@DerpTrolling - @GabenTheLord - @UGLegion

Let this be a warning to all. Nothing is safe from Derp

The message and the list of usernames and passwords can be found at the following location or website address:

Also, the group claims that they have the following information:

• 800,000 accounts from 2K Games and 500,000 credit card data
• 2 million Comcast accounts
• 620,000 Twitter accounts
• 1.2 million credentials belonging to the CIA domain
• 200,000 Windows Live accounts,
• 3 million Facebook
• 1.7 million EA origins accounts
• a total of 7 million usernames and passwords

Because we aren't sure if the information posted by hacker group is faked or not, we tried signing in with a few usernames and passwords. But, we were unable to sign in. We kept getting a message that too many attempts were made to sign into the accounts. I guess other people are attempting the same thing.

But, since we are not sure if the claim made by the group is true or not, as a safety precaution, we recommend changing your password immediately.

You may also enable Two-Factor authentication, which will prevent someone from gaining access to your account, even if they have your username and password.
