Earlier this week the fact that the Austin , Texas security firm Stratfor was hacked by Anonymous was announced. The Stratfor security site gave up details on hundreds of thousands of people that had used the site and its services in the hack. A hack of this sort is definitely not a good thing for a security firm to have happen.
If you wondered what was going to happen to all that stolen data, AntiSec is putting all of it online. In total there are 860,000 member details posted including 75,000 credit card numbers. Most of those cards are reportedly expired.
There is also 200GB worth of emails to be posted after they are redacted. It's worth noting that a security firm should have known better than to have credit card numbers stored to begin with. I am sure the damage to the reputation at Stratfor will be hard, if not impossible to overcome.
