Legal documents from the ongoing lawsuit between Israeli NSO Group and WhatsApp have revealed for the first time that the Israeli cyberweapons firm, rather than its government clients, is responsible for "installing and extracting" data from mobile phones targeted by its hacking software, The Guardian wrote.

These revelations emerged from sworn depositions of NSO Group employees, portions of which were made public on Thursday. The lawsuit, filed by WhatsApp in 2019, followed the messaging app’s discovery that 1,400 of its users, including journalists and human rights activists, had been targeted by NSO's spyware over a two-week period.

WhatsApp's case centers on allegations that the Israeli firm, not its international government clients, operates the spyware. NSO has consistently claimed that its technology is designed to combat serious crimes and terrorism, with clients bound by agreements to avoid misuse of the software. The company has also alleged it has no knowledge of who its clients target.
