HTExploit/Http Verb Tampering

So, as I have been running through some boxes and such I have noticed that some of the vulnerabilities discovered during scans is http verb tampering, but I can’t seem to find the HTExploit tool (used to be here Home | Mkit) and Google is turning up pretty ambiguous information.

If you have any resources or can give me a high level overview of that it would be greatly appreciated. Thanks!
