sandsifter: x86 fuzzer

s a n d s i f t e r : the x86 processor fuzzer
The sandsifter audits x86 processors for hidden instructions and hardware bugs, by systematically generating machine code to search through a processor’s instruction set, and monitoring execution for anomalies. Sandsifter has uncovered secret processor instructions from every major vendor; ubiquitous software bugs in disassemblers, assemblers, and emulators; flaws in enterprise hypervisors; and both benign and security-critical hardware bugs in x86 chips. With the multitude of x86 processors in existence, the goal of the tool is to enable users to check their own systems for hidden instructions and bugs.[…]
