While our update attempted to remove the backdoor automatically, it cannot confirm that it was fully eliminated. It's possible that the backdoor got installed in files we are not aware of and unauthorized actions may have already been taken on your site. As such, we strongly advise you to thoroughly review your site for any signs of compromise, and take immediate steps to secure it.
