"Court orders maker of Pegasus spyware to hand over code to WhatsApp", 29 Feb 2024

NSO Group, the maker of one the world’s most sophisticated cyber weapons, has been ordered by a US court to hand its code for Pegasus and other spyware products to WhatsApp as part of the company’s ongoing litigation.

The decision by Judge Phyllis Hamilton is a major legal victory for WhatsApp, the Meta-owned communication app which has been embroiled in a lawsuit against NSO since 2019, when it alleged that the Israeli company’s spyware had been used against 1,400 WhatsApp users over a two-week period...

[S]he sided with WhatsApp in ordering the company to produce “all relevant spyware” for a period of one year before and after the two weeks in which WhatsApp users were allegedly attacked: from 29 April 2018 to 10 May 2020. NSO must also give WhatsApp information “concerning the full functionality of the relevant spyware”.

Hamilton did, however, decide in NSO’s favor on a different matter: the company will not be forced at this time to divulge the names of its clients or information regarding its server architecture...

NSO declined to comment on the decision. The litigation is continuing...
