NSO Group Exploited WhatsApp Zero-Day Even After Lawsuit

NSO Group Technologies Ltd. continued to develop spyware that used multiple zero-day WhatsApp exploits even after the instant messaging firm sued the Israeli surveillance firm over violation of federal and state anti-hacking laws, revealed a court filing filed by the messaging app and its parent company Meta that was published on Thursday.

Court filings reveal that NSO continued using WhatsApp servers to install Pegasus spyware on phones by calling the targeted device, even after the messaging platform detected and blocked the exploit in May 2019.

The allegations stem from a series of cyberattacks against WhatsApp users, including journalists, dissidents, and human rights advocates.
