I would say that if it a scan comes from a dialup account it is
probably not compromised and is probably just a wannabe script
kiddie, but if the ip is not a dialup then the box is very likely to have
been compromised. I have seen many scans coming from what
appeared to be newly installed Red Hat Linux boxes, usually with
the default apache home page. It only takes a minute to install a
rootkit on a box once it has been found to be exploitable.
