I found some strange files in /stand namely -sh and [
This got me somewhat suspicious, so I installed chkrootkit.

It says:
Checking `chfn'... INFECTED
Checking `chsh'... INFECTED
Checking `cron'... not infected
Checking `date'... INFECTED
Checking `ls'... INFECTED
Checking `ps'... INFECTED
Checking `lkm'... You have     9 process hidden for ps command
Warning: Possible LKM Trojan installed

Does this mean I got hacked?

Thanks for any help
