“In 2016, Researchers from the University of Illinois left 297 unlabeled USB flash drives around the university campus to see what would happen. 98% of the dropped drives were picked up by staff and students, and at least half were plugged into a computer in order to view the content. For a hacker trying to infect a computer network, those are irresistible odds” (Kaspersky Labs). Plug-and-play (PNP) technologies have become very common in today’s world, but there’s no reliable way to ensure that everything plugged into a computer will play nicely. Operating System Customs (OSC) aims to maintain the “plug-and-play” name by introducing a new layer to ensuring that everything plugged in is verified as 100% safe. This project ensures your computer’s safety as well as your network’s, identifying your external medium and scanning it to verify if a virus/malware was installed without your knowledge. After the scan, it’s either verified to be safe or dangerous and lists off any discovered corrupt files. OSC allows users to operate in a safe network and grant system administrators peace of mind.
