This morning I received a flurry of unexpected email messages from Best Buy's "Reward Zone," one of those preferred customer programs. I was reading email when the messages arrived, so I immediately tried to log in to the account and check its status. I couldn't log in, so I immediately called Best Buy.

I've been looking at the various files LulzSec has uploaded from their victims. These include Sony (several different sites on separate occasions), PBS, the game company Bethesda, Fox TV, Nintendo, and a computer security company called Unveillance. They actually defaced the PBS site, posting a bogus article claiming that dead rapper Tupac was located alive.

My initial impression is that these folks are using some fairly simple attacks, like SQL injection, to retrieve a lot of the data. Note that in most cases they didn't actually deface the victim. I suspect they would have if they could have. Thus, they're taking advantage of the weaknesses they do find.
There's been buzz in computer hardware blogs over the past few days about how faster processors (and GPUs in particular) are rendering strong passwords "useless." One experimenter, named Vijay Devakumar, posted a description of his success at cracking passwords, which has been recently picked up by bloggers on

He has posted (pasted, actually) a series of statements on pastbin.com that describe what happened and provide some evidence to support his claim. Note that the link above will probably go sour in a while, since Pastebin's policy is to recycle the pasted storage periodically.
