I login and I'm connected as if I were Russian. And everytime I open a game I'm connected as a different user.

What the hell is going on?

Major sites are reporting the issue:

To repeat, do NOT visit any Steam Store links. Doesn't matter what you want to do, do not visit any of them.

.@Mrluga Don't do anything. Do not visit any Steam Store url. This include using store in the Steam client.

By the way, this is not a security breach. This is page caching gone rogue. Most likely not respecting Cache-Control headers.

It's winter sale. What did you expect?

Well...I didn't expect being able to see the info of a random Russian user....

Yeah, I noticed too. It won't let me buy games or check my wishlist and some store pages are in Japanese for some reason. Pretty sure that it was hacked.  Hopefully we get a fix soon.

EDIT: Everything seems normal again.  Guess they fixed it?  Other than buying things.

Now we know what the psn/xbl hackers were up to.

Yea, its messed up right now. I did picked up Final Fantasy XIII and XIII-2 on sale the other day.

I'm still being redirected to random users

Aw it'd be cool to be signed in as someone else v.v XD I logged in and I was fine

Yeah, still fucked up here. My store turned into Norwegian or something, and now it's Spanish or something like that.

Wait, nevermind -Steam turned Korean for me just now and fucked up XD
