Not really shocking or new but kind of interesting. Why would they use 0days on security researchers. My guess is it's a test with upside. On the one hand if it works on a security researcher, you can go "live" because you got a good one and on the other hand you estimate that in the long run you'll get 1+x 0days out of the deal from said researcher.

As a security researcher it also presents an interesting situation. If you're careful enough and can pretend to be dumb enough, you might be able to harvest fresh attack vectors/0day etc. "for free" but the downside is if you overestimate yourself you'll get pwned.
