chkrootkit and rkhunter are too old ?

[KLEIN Stéphane <stephane@is-webdesign.com>]

Hello,

I look for root kit checker. I found this tools :

* chkrootkit (http://www.chkrootkit.org/)
* rkhunter (http://rkhunter.sourceforge.net/)

chkrootkit last version date from 30/09/2006 (1.2.9) and rkhunter date 
from 10/10/2006. This tools are near two year old. There aren't new 
rootkit since this date ? if yes, there aren't other tools to check my 
box ?

Else, what can I use to test integrity of my system ?

Thanks for your help,
Stephane
