Quadream’s REIGN spyware said to have used same exploit as NSO Group’s Pegasus, before being patched in September; clients also include Saudi Arabia

Bill Marczak, a security researcher with Citizen Lab, told Reuters that the company’s so-called “zero-click” abilities appeared to be “on par” with NSO’s. Three of the sources said NSO and Quadream’s exploits were similar because they leveraged many of the same vulnerabilities hidden deep inside Apple’s instant messaging platform and used a comparable approach to plant malicious software on targeted devices, in order to gain unauthorized access to data.
