There is a well documented scam going around where you will receive a message which tells you your website has been hacked and they have all of your data, and data from your clients and they are going to contact everyone and sell the data and cause you a load of grief. (I have paraphrased that to keep it short). If you get anything like that please do the following:
1). Don’t panic
2). Send a copy of it to me
3). Wait until you hear back from me
Do not pay anyone anything, or engage in a conversation. The language including grammatical errors are recorded in multiple places on the web. It is a well known scam. Another one which is designed to instil panic in the recipient.
While I am on the subject there is a second one which claims to have taken over the camera on your computer and has images of you in compromising situations (I will leave that to your imagination!), that one is another scam. I have not seen it recently, but what goes around comes around eventually.
Both messages will come from a non traceable source, and both are asking you to deposit bit coins in an account.
