NSO’s Pegasus software has the ability to infect iPhones and Android devices, allowing operators to extract messages, photos and emails, record calls and secretly activate microphones and cameras.
NSO Group said its tools were made to target terrorists and criminals.
The group has allegedly also been used on activists, politicians and journalists.
NSO Group says it only supplies Pegasus to military, law enforcement and intelligence agencies from countries with good human-rights records.
Earlier this month, US officials placed the company on a trade blacklist, with the government stating that the software had “enabled foreign governments to conduct transnational repression, which is the practice of authoritarian governments targeting dissidents, journalists and activists”.
Apple’s move follows a lawsuit launched in 2019 by WhatsApp which is still working its way through the US court system.
In its initial court filing, WhatsApp said NSO Group “developed their malware in order to access messages and other communications after they were decrypted on target devices”.
Other tech firms, including Microsoft, Meta Platforms (formerly Facebook), Google-owner Alphabet and Cisco Systems have all previously criticised NSO.
