Re: Ever-morphing killer bug more persistent than an Xenomorph in a Space Trucker cargo ship
could it be that that bug hunter has "sources" at the NSA?
Assuming the "bug hunter" in question is SandboxEscaper: It's certainly possible, but hardly necessary. There was a HITB talk a couple years back about finding and fuzzing ALPCs. It's a well-known area for Windows security research in the hacker community. This is just a typical "Microsoft provided a service with elevated privileges and didn't establish the correct boundaries" bug.
