Does anybody else received mail from BundleStars to change password? Possible hacker attack

Yep, it's legit.

I actually was prompted to reset my password yesterday, and they were just slow in sending these emails regarding the issue.

Seems I got an email from Rockstar Social club yesterday informing me that my password there was changed.
Haven't touched that account in years, I think. So that's not good...

Bump

Yeah, I received the mail.
Unfortunately, after I logged in to the website and reset the password, I found the unreveal keys of several purchased bundles become all reveal.
Then I put these code to steam client, got the message "Deplicate Product Code". But my account don't have these games.
Already sent several mails to Bundle Stars, but they insist that my account has no access from other country.
→So they means that these keys were all uesd by me? I was disappointed with Bundle Stars' reply.
I'm Bundle Stars' lover before, but now..

Still trying to communicate with Bundle Stars now.
