In a landmark decision, a US federal court has permanently barred Israeli spyware company NSO Group from targeting Meta’s WhatsApp messaging platform, marking a major victory for privacy advocates and a potentially devastating blow to the controversial surveillance firm.
The ruling, handed down by US District Court Judge Phyllis Hamilton on Friday, prohibits NSO from attempting to break into or exploit WhatsApp’s systems ever again. The injunction forms part of a 25-page decision that also drastically reduced the company’s financial penalties.
Court Reduces Damages, But Imposes Ban
The court had previously ordered NSO Group to pay about $167 million in punitive damages to Meta, the parent company of WhatsApp. However, in this latest judgment, the amount was slashed to $4 million, offering NSO some relief on the financial front.
Despite the reduction in damages, the permanent injunction is seen as a much more serious blow. It effectively prevents NSO from using or developing exploits targeting WhatsApp — one of the most widely used encrypted messaging platforms globally, with over two billion users.
Judge Hamilton emphasized that NSO’s continued targeting of WhatsApp would cause “irreparable harm” to Meta and its users, making the injunction a necessary measure to protect user privacy and data integrity.
NSO Warns of Existential Threat
The ruling could have dire consequences for NSO Group, which has long been criticized for selling its Pegasus spyware to governments and agencies accused of human rights abuses. Pegasus is known for exploiting software vulnerabilities to gain access to smartphones, enabling operators to monitor calls, messages, and even activate cameras remotely — often without the user’s knowledge.
In court filings, NSO had previously argued that such a ban would “put NSO’s entire enterprise at risk” and potentially “force NSO out of business.” The company insists that its tools are designed for legitimate purposes, such as tracking terrorists and serious criminals, and that it does not directly operate the spyware itself.
However, human rights organizations and investigative journalists have linked Pegasus to the targeting of journalists, activists, opposition figures, and diplomats across multiple countries, sparking widespread international condemnation.

Meta executives hailed the ruling as a historic step toward protecting users from invasive surveillance.
“Today’s ruling bans spyware maker NSO from ever targeting WhatsApp and our global users again,” said Will Cathcart, head of WhatsApp, in a post on X (formerly Twitter). “We applaud this decision that comes after six years of litigation to hold NSO accountable for targeting members of civil society.”
Meta first filed a lawsuit against NSO in 2019, alleging that the company had exploited a WhatsApp vulnerability to install Pegasus spyware on approximately 1,400 phones, including those of journalists and human rights defenders.
NSO Responds: ‘We Will Review the Decision’
In a statement following the ruling, NSO Group said it welcomed the 97% reduction in damages but downplayed the impact of the injunction, emphasizing that the restriction applies only to NSO itself, not to its government clients.
“The injunction does not apply to NSO’s customers, who will continue using the company’s technology to help protect public safety,” the company said. “We are reviewing the decision and will determine our next steps accordingly.”
Still, the court’s ban on targeting WhatsApp may significantly restrict NSO’s operational scope, as the messaging service remains one of the most common platforms used by journalists, NGOs, and political leaders worldwide.

New Ownership and Uncertain Future
The decision comes shortly after reports surfaced that NSO Group had been acquired by a consortium led by Hollywood producer Robert Simonds, best known for his work on blockbuster films. The acquisition, revealed earlier this month by TechCrunch, aimed to help the company stabilize financially amid mounting lawsuits and global scrutiny.
Neither Simonds nor his representatives have commented on how the new ruling will affect the company’s future operations.
Broader Implications for Digital Surveillance
Legal experts suggest the case could set a precedent for how US courts handle similar disputes involving spyware and cybersecurity breaches. The decision reinforces the notion that digital platforms have a right to defend their systems from intrusive surveillance technologies, even when those tools are marketed for government or law enforcement use.
It also underscores the growing international backlash against companies involved in the surveillance industry, as governments and technology firms push for stronger privacy protections.
For NSO Group, the ruling adds yet another layer of legal and reputational pressure. Between the US court ban, financial strain, and ongoing investigations into its activities in Europe, the future of the once-dominant spyware maker looks increasingly uncertain.
