Rootkit Detection In Nix

myth

Feb 21 2005, 06:02 AM

Homepage: http://www.chkrootkit.org/

Just discovered this program, no-one has linked to it yet, thought you guys would find it useful (even to check if your rootkit is detected)

Im not sure how it updates it database, maybe via versions (currently 0.44), so atm, i dont use it as a last resort. Also, via debians apt-get install chkrootkit, a configuration prompt was opened to run the command daily, but im a little confused where the logs are left ... Theres not alot i know about cron jobs...

/etc/cron.daily/chkrootkit

CODE

#!/bin/sh -e

CF=/etc/chkrootkit.conf

if [ -e $CF ]; then
. $CF
fi

if [ "$RUN_DAILY" = "true" ]; then
date >> /var/log/chkrootkit/daily.logs
chkrootkit $RUN_DAILY_OPTS >> /var/log/chkrootkit/daily.logs
fi

Thats what i edited mine to look like, make sure that the necessary files / folders exist with proper permissions....

Example of output of 'chkrootkit'

Guys, found another proggy. Probably better because you can run updates via cron-jobs....
