I have an EPSON PROJECTOR (model EB-824H) And I would like to use it in our company. As I know (but not sure) this kind of projector has no WIFI,no network card and there is no HD in this PROJECTOR It also has 2 USB (one to PC) What security threats or risks can arise from connecting this kind of projector to a network PC via USB? Can someone upload malware to this projector ( maybe something that writes to the ROM, or crossing into the network...)?
The only security threat with this product is someone stealing it. Without a network it has no remote attack surface. Without long term storage there is really nothing to hack.
It does have a password, but who cares? Probably one of the least useful password protected resources I have heard of. It has USB host, and so you might be able to corrupt memory with a specially crafted usb device or video files, but again this is attack is worthless because no one cares. This is not a strategic resource.
