Looks like it's also relying on LLVM for disassembly? Ouch; that's an incredibly bad idea if you're trying to analyze malicious or unusual code (it's not designed for that), but I guess it's the easiest for a proof of concept like this.

Although, there's no way an AV company doesn't have its own disassembler, but those are almost always treated as trade secrets (especially the stuff that isn't in the spec / the spec is wrong). They'll probably hook it up to that before doing any real work with it themselves.
