System and method for replay of peripheral device attacks
Disclosed herein is a computerized method for emulating processing of a peripheral device including operations of providing an insertion emulation signal to a computing device emulating insertion of the peripheral device to a port of the computing device, intercepting a request for a device descriptor of the peripheral device from a PnP manager operating on the computing device, providing a device descriptor of the peripheral device to the PnP manager, wherein the PnP manager is configured to enumerate the emulated peripheral device, intercepting one or more universal serial bus (USB) request blocks (URBs) from the PnP manager, and responsive to each of the one or more URBs, providing a response to the PnP manager. The insertion emulation signal may emulate a voltage transition on a data line of the port of the computing device. The peripheral device may adhere to a USB standard.
