I am running chkrootkit-0.22 as a cron job every day. Yesterday, I installed
a number of patches on a RaQ3, including the kernel update. Today,
chkrootkit reports the following:
Checking `du'... INFECTED
Checking `ls'... INFECTED
Checking `ps'... INFECTED
Checking `bindshell'... INFECTED (PORTS: 1524 12321)
Everything else is reported as being "not vulnerable". The commands above
were not infected yesterday.
Am I hacked, or could this be erronous reporting due to the kernel update?
e.g. would chkrootkit cry out if some commands change their timestamps?
