If you’re one of those stern parents worthy of being called a fascist, then allow me to direct your attention to the SnoopStick. This USB device comes imbued with software that allows you to monitor remote systems.
Simply plug the SnoopStick into a PC that needs spying and 60 seconds later its compromised and you can snoop on it from anywhere. The software is completely invisible, so basic users probably wouldn’t be able to discover it.
To monitor the systems, just plug the SnoopStick into your own system and select the snoop function. It will show logs of all the systems you’ve compromised. Great.
