• Discover-Tech was certified as a safe supplier by Google, Microsoft, Yandex, and the IAB, and had ties to Israeli spyware firms including NSO Group.
• Among its targets were Al Jazeera workers, and it also facilitated attacks by other mercenary spyware companies including Candiru (now Integrity Labs).
