Hacked Help
Looks like we had a hack on one of our servers. We are not sure how they did what they did but we know this:They created a user www
They had previously compromised 5 other accounts of real users first.
They altered these /bin files (at least) so that we cannot do anything with them.
login
ls
netstat
ps
On a move of the files we get these errors:
/newbin/mv: cannot unlink `ls': Permission denied
/newbin/mv: cannot remove `ls': Permission denied
Obviously we have a clean /newbin directory pulled over.
We cannot manipulate the files as the user (one of our customers) or root. No chown, chmod, mv, rm, rm -rf nothing.
Can anyone point me to a site that may have a fix or put it here? I know I am forgetting some basic unix thing to get control of the files.
