If it is possible to compromise systems without the admin/owner/anyone knowing they have been compromised and cause no change to the integrity of THEIR data, and do them no harm other than host 10 Mb on their/the/a/it/uh box... And in the situation they do, cannot read the information (since it is only a small piece of it) And there are tons of systems that are up 24/7 (think pacemakers running telnet, traffic lights, police/ambulance/fire radio, cell phone towers) Is it possible or is there anyway that it has already begun, to construct a GREYnet (similar to darknet) off of ICS/SCADA systems that have free, unused space?
