I have a web form created in the Adobe Business Catalyst CRM and someone has placed a Man in the Middle (MitM) hack on our site or wherever and is intercepting the web form then contacting the user who submitted the form and offering them their products using the same name as my website.
So this is a two-part question. How do I get rid of and prevent this from happening again and is there any legal action I can take against the MitM hackers?
