Steam Had A Very Rough Christmas With A Major Security Issue

Steam has had a very rough day with first being hit by a DDoS attack and then a major security hole.

The security issue looks like it might be resolved now, but resulted in gamers being able to see other account holder's information. Seeing other accounts included partial credit card information, addresses, and other personal information. For a while, the Steam store was completely shut down. The issue seems to stem from some caching issues due to account holders being presented with the wrong information.

I haven't seen Valve issue any formal state yet on the matter, but there's much discussion about today's Steam woes via Reddit and elsewhere.
