It is a shell +script using common UNIX/Linux tools like the strings and grep commands to +search core system programs for signatures and for comparing a traversal of the +/proc filesystem with the output of the ps (process status) command to look for +discrepancies. + +It can be used from a "rescue disc" (typically a LiveCD) or it can optionally +use an alternative directory from which to run all of its own commands. These +techniques allow chkrootkit to trust the commands upon which it depends a bit +more. + +There are inherent limitations to the reliability of any program that attempts +to detect compromises (such as rootkits and computer viruses). Newer rootkits +may specifically attempt to detect and compromise copies of the chkrootkit +programs or take other measures to evade detection by them. diff --git a/system/chkrootkit/chkrootkit.SlackBuild b/system/chkrootkit/chkrootkit.SlackBuild new file mode 100644 index 0000000000000..df19761ddeddf --- /dev/null +++ b/system/chkrootkit/chkrootkit.SlackBuild @@ -0,0 +1,88 @@ +#!/bin/sh + +# Slackware build script for chkrootkit + +# Copyright 2007 Michiel van Wessem (http://michielvwessem.wordpress.com) +# All rights reserved. +# +# Redistribution and use of this script, with or without modification, is +# permitted provided that the following conditions are met: +# +# 1.
