We've experienced some security issues which were dealt with immediately. Fortunately we do not believe at this time that any user data was accessed or sent to anyone (emails, passwords, etc) because the malicious code we found was not able to run on our server. Furthermore, the code itself was buggy and likely would not have reached its destination with any information if it were able to.
It's good practice to use a different email and password for each site you visit, or at least for the ones you have bank details attached to, so if you are worried about your security changing your password would be a great place to start!
