Wordpress Plugin to Mirror Links to Homepage?

I came across this site here (apnicservices d0t c0m) and noticed that every link for categories, archives, and articles (old indexed article links like this one here (apnicservices d0t c0m/articles/low-cost-teeth-cleaning-333.htm/)from previous domain owner, not current articles) is just a mirror of the homepage.

Is there a plugin that can easily do this for every link on a site?
