IOCTL Fuzzer is a tool designed to automate the task of searching vulnerabilities in Windows kernel drivers by performing fuzz tests on them.
The fuzzer’s own driver hooks NtDeviceIoControlFile in order to take control of all IOCTL requests throughout the system.
While processing IOCTLs, the fuzzer will spoof those IOCTLs conforming to conditions specified in the configuration file. A spoofed IOCTL is identical to the original in all respects except the input data, which is changed to randomly generated fuzz.
IOCTL Fuzzer works on Windows XP, 2003 Server, Vista, Windows 7 and 2008 Server.
