I just got a message via Steam from Valve (the online game library/shop) that they got hacked.
If you have used a credit card or debit card on their system, I would advise checking your bank statements or cancelling your cards.
I just cancelled all my bank cards, especially now nearing Christmas you do not need this type of grief, especially if someone has your details.
I do not know how many of you buy direct from Steam, but I hope you act on this and protect yourself.
