I am curious about the transfer of malware from one machine to another by use of a KVM Switch.
I am looking to connect a KVM switch between my computers up to my new testing machine, and want to make sure that if something happens to the testing machine, that I somehow wont infect other computers attached via the KVM Switch.
Note: for those who don't know what a "KVM Switch" is, it is essentially a device that connects a Keyboard, Video-Device, and/or a Mouse between multiple computers that can be switched with the press of a button. There are many kinds that do many things. Some are specific to one or the other( i.e., keyboard and mouse only), and others do all sorts of cool things such as audio.
Note 2: The "Testing machine" is a machine that will be used for vulnerability learning and testing of applications for exploits via sites such as OWASP. I am not sure what I will encounter when doing this, but since these sites are dedicated to vulnerability testing, and meant to be exploited, who knows what people could do to it that could be very bad for the network and it's computers.
So essentially is it possible to transfer malware through a KVM switch, and how likely is something like this to occur?
EDIT: Just found this Can a KVM switch be vulnerable through a VGA port?
Not sure if this would be an issue in my case, but thought it would be an interesting post to add. It seems the issue is the "VGA Port," but I would assume USB could also be interfaced and connected to, to execute malicious code... The question is... How likely is that to happen? I would assume it would be easier to connect over USB, than VGA, but not sure if something special is needed in how the malware transfers over.
