Today, LulzSec attacked Eve Online, Minecraft and Escapist Magazine. It looks like Minecraft and Escapist were simple DDOS attacks, but Eve may be more sinister with their claim to have wiped the login server.
The same group recently hacked a porn website and posted the emails and passwords for several hundred users online.
This brings up a really good question. Why would you trust anyone with "your password?" If I log into Facebook, they now now "my password." If I use that same password anywhere else I'm essentially trusting that not only will Facebook not be evil with my password, but that they are smart enough to keep ALL hackers out of their list of passwords so that "my password" is kept secure. It's like giving a stranger on the street a copy of the key to your car and hoping they won't either pass it on or use it themselves.
Never, never use the same password for multiple sites, unless you're comfortable with losing all of those logins at the same time. That means your bank account, email account and facebook account really must all have separate passwords.
Also, if you use any service that supports "two-factor authentication" please, please activate it. GMail and Facebook both support two-factor authentication methods now that require more than just your password to login.
