WhatsApp will soon be granted access to explore the "full functionality" of the NSO Group's Pegasus spyware—sophisticated malware the Israeli Ministry of Defense has long guarded as a "highly sought" state secret, The Guardian reported.

Since 2019, WhatsApp has pushed for access to the NSO's spyware code after alleging that Pegasus was used to spy on 1,400 WhatsApp users over a two-week period, gaining unauthorized access to their sensitive data, including encrypted messages. WhatsApp suing the NSO, Ars noted at the time, was "an unprecedented legal action" that took "aim at the unregulated industry that sells sophisticated malware services to governments around the world."

Initially, the NSO sought to block all discovery in the lawsuit "due to various US and Israeli restrictions," but that blanket request was denied. Then, last week, the NSO lost another fight to keep WhatsApp away from its secret code.
