Big Tech giants, such as Microsoft, Google, Cisco, VMWare, and the Internet Association, have decided to back Facebook in a major legal battle against the NSO Group over allegations that the latter exploited a critical vulnerability in WhatsApp to inject surveillance malware into users’ devices.

“Between approximately January 2018 and May 2019, Defendants created WhatsApp accounts that they used and caused to be used to send malicious code to Target Devices in April and May 2019.

Facebook further alleged that because of NSO Group’s covert activities that caused damage to its reputation and destroyed the goodwill between the company and its users,…
