rIP - Reverse IP Tool

Posted in IT, Security, Tools at 12:40 pm by Tyler Reguly

This is actually pretty cool... It's a new tool (Web-based) that came across the Web Application Security Consortium mailing list. Let's take a look at the tool in action first, example with ComputerDefense.org.

Showing records 1 - 13 out of 13 for www.computerdefense.org (82.165.158.149).

capri-beauty.com computerdefense.org
hometownssm.com hometowntoronto.com
htregz.com korahgrads.com
numerophobe.com pythongod.com
reguly.org securitybloggers.net
spammailbag.com themoviegeeks.net
topsykrett.com

Those are indeed the domains I own, that reside on the same IP as ComputerDefense.org. Currently the database is restricted to .com, .net and .org but it's still fairly impressive. A method of determining vhosts is a great asset to penetration testers and security researchers.

The tool is available from a group called CRUSH.  It requires that you validate you aren't a bot via a text / colour based CAPTCHA, however after the first time, you are good to make subsequent requests.

I'm going to have fun playing with this tool, taking a look at certain companies / websites and seeing what other domains they host on the same server...
