Facebook has filed a lawsuit against Israeli company NSO Group, creator of the Pegasus spyware, alleging that it was behind the massive WhatsApp hack earlier this year. In May, a zero-day vulnerability was found in WhatsApp s messaging platform, exploited by attackers who were able to inject spyware onto victims phones in targeted campaigns. Facebook says that the attackers used servers and internet-hosting services that were previously associated with NSO, Will Cathcart, head of WhatsApp, in a Tuesday post.
