Udemy course missing

The md file says, "The full course on Hacking and Securing Web Java Programs is available in https://www.udemy.com/hacking-securing-java-web-programming/"

But when you follow that link you get a message that the course has been removed from Udemy. Do you have a copy of it elsewhere?

Was there a problem with it that Udemy didn't like?

Can I help you fix it?
