Our system alerted us that someone tried to sign in to around ~200 accounts with a VALID password! Most accounts are safe as we require to confirm new device with email. However, it means that some casino was hacked and those data were used to sign in to our system.
Currently, we block those accounts proactively. Unfortunately, one user was affected as it seems that password was the same for email as well and the hacker was able to withdraw funds.
We recommend changing the passwords ASAP and turn on 2FA.
