Two of Peter Gray’s past engineering projects, prior to becoming the CTO of Coinkite:

• Writing the firmware and software for an OEM-sold USB keylogger
• Conceiving and programming KVM-over-IP hardware for remotely viewing and controlling computers

The keylogger captured keystrokes without software on the target computer. The likely OEM product, KeyGhost, was sold as a dongle or concealed inside a keyboard.

The KVM hardware let a remote operator see the screen and control the keyboard and mouse, even before the OS loaded.
