That's the URL they cite. From what I can see, well I'd describe this as a good start at best. Their tool relies on MITM access to do it's DDoS work & that's just of limited utility at best. They simply aren't going to have that type of access except over devices that are somewhat ironically Japan-only.

That aside, the disablement thing seems more like it'd be at best an edge case capability.

There's a lot of hand waving about the quasi-offensive capabilities there, but I'm gonna call BS on this until they cough up real data.
