NSO Group

We're starting to see some information on the Israeli cyberweapons arms manufacturer that sold the iPhone zero-day exploit to the United Arab Emirates so they could spy on human rights defenders.

EDITED TO ADD (9/1): There is criticism in the comments about me calling NSO Group an Israeli company. I was just repeating the news articles, but further research indicates that it is Israeli-founded and Israeli-based, but 100% owned by an American private equity firm.
