LulzSec are a group of hackers who have stolen and published piles of data, as well as defaced many corporate and government websites over the last two months.
LulzSec has released an insane amount of user data from tons of different organizations. So, you’re going to want to make sure that your information wasn’t part of the leaks.
You can do that with a quick search here.
My feelings on LulzSec are complicated to say the least, so I will dedicate an entire post to the matter.
In the meantime, I recommend you check your emails as well as your loved one’s emails to make sure their data isn’t part of the leaked information. If it is, it’s time to change your passwords… Even if your data isn’t part of the leaks, you should change your passwords regularly.
Practice safe computing.
