Eight Things We Learned from the WhatsApp vs. NSO Group Spyware Lawsuit
Wondering how WhatsApp defeated NSO Group in their high-profile spyware lawsuit? What exactly was the spyware’s method of attack? And why did a jury award WhatsApp over $167 million in damages? This landmark legal battle, spanning over five years, uncovered critical insights into how Pegasus spyware operated and exposed NSO Group’s continued targeting of WhatsApp users, even amid legal challenges. For those searching for a comprehensive breakdown of WhatsApp’s victory and its implications for digital security, here are eight key takeaways from this pivotal case.
On May 6, 2025, a U.S. jury ruled in favor of WhatsApp, ordering NSO Group—infamous for its Pegasus spyware—to pay more than $167 million in damages. This verdict closed a lengthy lawsuit that began in October 2019 when WhatsApp accused NSO Group of hacking over 1,400 users by exploiting a vulnerability in WhatsApp’s audio-calling feature. The spyware attack was particularly sophisticated, requiring no user interaction, making it a "zero-click" exploit.
During the weeklong trial, witnesses from both sides testified, including NSO Group’s CEO Yaron Shohat and key WhatsApp security team members. The trial revealed how NSO Group constructed a specialized “WhatsApp Installation Server,” enabling the Pegasus spyware to infiltrate users' phones simply by placing a fake call. This approach mimicked genuine WhatsApp communications to evade detection—only a target's phone number was necessary to trigger the attack. According to WhatsApp’s legal counsel, this method was a significant breakthrough in spyware technology, allowing seamless and silent device compromise.
Despite facing a lawsuit, NSO Group admitted to continuing its attacks on WhatsApp users even after the case was filed. Tamir Gazneli, NSO’s vice president of research and development, confirmed that several versions of the zero-click spyware—codenamed “Erised,” “Eden,” and “Heaven”—were actively used from late 2019 through mid-2020. Collectively known as “Hummingbird,” these spyware variants demonstrate NSO Group’s persistent exploitation of WhatsApp vulnerabilities amid ongoing legal scrutiny.
The court documents and over 1,000 pages of trial transcripts also unveiled disturbing details about NSO Group’s clientele and operational practices. It was revealed that NSO had cut ties with 10 government clients for abusing Pegasus, and identified three specific state actors using the spyware: Mexico, Saudi Arabia, and Uzbekistan. These revelations highlighted serious concerns over privacy violations and human rights abuses linked to commercial spyware.
This case sets a major precedent in cybersecurity law, showing that companies like WhatsApp can hold spyware makers accountable for invasive and unlawful digital surveillance. It underscores the importance of robust legal and technical defenses against advanced persistent threats targeting everyday users. For digital privacy advocates and security professionals, WhatsApp’s victory signals a step forward in combating cyber espionage and protecting user data.
For those interested in cybersecurity, spyware litigation, or digital privacy, following the WhatsApp vs. NSO lawsuit offers valuable lessons on how cutting-edge spyware operates and how legal systems are evolving to tackle these challenges. Staying informed about zero-click vulnerabilities, spyware campaigns, and legal developments can empower users and companies alike to safeguard their communications in an increasingly hostile digital landscape.
