Cant delete or chown file as a root
some hack script suddenly appear in the /root directory of my VPS. Lets call it "badscript"
but i cant delete it or chown it being root..
-rwxr-xr-x 1 root root 1.2M Jul 18 12:34 badscript
rm: cannot remove `badscript': Operation not permitted
chown: changing ownership of `badscript': Operation not permitted
Please any idea how to block that person who added this script to my linux redhat server?
