In last few days some of BitMarket accounts were compromised. Because it's not just one case, I decided to disable the site until I'm certain how it happened.
From what I can tell now, accounts were accessed normally, using their respective logins and passwords. We store only hashes of our passwords in database, so it's impossible to get them from there.
Attacker used the TOR network, so tracking him by IP is useless.
Early reports suggest that this may be somehow connected with Mt. Gox. That's why I want everyone affected to confirm if they have indeed had Mt. Gox accounts with same usernames and passwords as on Bitmarket.
I'll update this post with more information as soon as I learn something.
Update: This doesn't affect most of you. Only a very limited amount (about 15) of accounts were compromised.
It affected me but I can't reply in the original topic because I'm new on this forum... nice!
So I don't have any account on Mt. Gox... what I have to do if I want to continue to use bitmarket?!
Thanks.
