I am not aware of the situation entirely myself but at the moment having just about any contact with steam could risk any account information you have including emails, credit card information, or any other information you have in steam
DO NOT:
Try to remove credit card information through steam it could only further the problem I would recommend closely monitoring your bank account the same goes for paypal
YOU CAN:
Safely detach Paypal from steam through Paypal.com but DO NOT go to steampowered.com or use Steam at the moment
this is all the information I have so far :c
EDIT: Here is the post on the steam reddit for likely more specific/accurate information: https://www.reddit.com/r/Steam/comments/3y7r0b/do_not_login_to_any_steam_websites/
EDIT: It appears not any contact with Steam but any contact with the steamstore or steamcommunity however I have chosen to and recommend avoiding steam altogether just to be safe rather than sorry
