Hi， Thanks for providing this, we don't think it is our daatabase got hacked, but we think it could be something else with the hacker, it seems to have stopped. and we are investigating the email headers to see if there are anything at all we can find out.
it seems to have affected  a few of our customers, but not all, we are trying to find out which part could that be.

for those who got this spam email, have you contacted us recently ? i.e. through google group forum or through the contactus#minereu.com ?
