We've temporarily taken TweetDeck services down to assess today's earlier security issue. We'll update when services are back up.

Shortly after the problem surfaced, TweetDeck told users the problem was fixed, only to inform them that in fact, it was not. TweetDeck has temporarily shut down their service to investigate the issue.
If you use TweetDeck, your best bet right now is to log out and stay out until TweetDeck gives the official all clear. You can follow their Twitter feed for updates.
