Nearly two dozen journalists and other staffers working for El Faro, a digital newspaper based in El Salvador, are suing NSO Group for unleashing Pegasus spyware — malware they say was used to steal their most sensitive information, putting their safety in danger.

Along with ASO Group Technologies, its Israeli parent company, Q Cyber Technologies is also named as a defendant in the lawsuit.

The 22 plaintiffs from El Faro are getting an assist from the Knight First Amendment Institute at Columbia University in their litigation. Attorneys for the El Faro group say that because Apple servers in Silicon Valley were compromised by Pegasus to monitor the newsroom, they have filed the lawsuit in the US District Court in Northern California.
