[Zerviscos]

A Heartbleed bug has been discovered. Any steam services(steamdb, steamcommunity, etc.) are currently and potentially dangerous at the moment.
Here's the tweet hours ago.

Though, I don't know if you should even click the link('cause I don't know how great the issue is). It's been said that you should not try to do anything rash as of the moment.
Don't log into, use, or log off of steam or any >other websites<. The bug effects the heart of encryption key libraries, it will leave your data vulnerable for eavesdropping without any trace of that having been done.
It's not known which users have been greatly affected, but it is advised that everyone should be careful, as a lot of web servers use OpenSSL.

[Think Komachi with a Rifle]

In addition to all yahoo services (and porn, and VPNs),
 the other thing of note is all versions of World of Tanks Website are vulnerable.

This site is also vulnerable.
Might want to fix that.

support.steampowered.com is clear according to your tracker now.

There's a LOT of things that are vulneurable as a result of this, actually; Steam's just one of probably hundreds of thousands of places that could be affected.  The security hole is a weakness in a security system that's basically become a longstanding standard that huge amounts of things are built on.
