U.S. Judge Rules Against NSO Group in WhatsApp Pegasus Spyware Case

In a significant win for privacy and cybersecurity, Meta-owned WhatsApp emerged victorious in its legal battle against the Israeli spyware vendor NSO Group. A U.S. federal judge in California ruled in favor of WhatsApp, condemning the exploitation of a security vulnerability to deliver the infamous Pegasus spyware.

?? Key Takeaways from the Ruling:

• Evidence Against NSO Group: The court found that NSO's Pegasus spyware had infiltrated WhatsApp's California-based servers 43 times in May 2019, exploiting a critical zero-day vulnerability (CVE-2019-3568, CVSS score: 9.8).
• Non-Compliance with Discovery Orders: U.S. District Judge Phyllis J. Hamilton criticized NSO Group for withholding key evidence, including the Pegasus source code, and limiting discovery to Israeli citizens present in Israel.
• Breach of Contract: The court ruled NSO Group violated WhatsApp's terms of service by using the platform for malicious purposes, such as reverse engineering and delivering harmful code.

"This ruling is a huge win for privacy," stated Will Cathcart, head of WhatsApp at Meta, on X (formerly Twitter). "Spyware companies cannot hide behind immunity or avoid accountability for their unlawful actions."

?? A Long-Running Legal Battle: The lawsuit, originally filed by WhatsApp in late 2019, accused NSO Group of installing Pegasus on over 1,400 devices. The spyware leveraged WhatsApp's voice-calling feature to infiltrate targets' phones, even if the call wasn’t answered. Evidence later revealed NSO continued these attacks until May 2020.

While NSO Group claims its tools are designed exclusively for governments to combat terrorism, human trafficking, and other serious crimes, mounting evidence has shown Pegasus being weaponized against journalists, activists, and politicians globally.

?? The Bigger Picture: This case highlights the urgent need for stricter regulation and accountability in the commercial spyware industry. Apple has also been at the forefront of countering spyware threats, introducing measures like Lockdown Mode and advanced threat notifications to protect users. These steps have been applauded by cybersecurity experts as transformative for combating state-sponsored attacks.

Looking Ahead: The next stage in this legal battle will focus on determining the damages owed by NSO Group. For privacy advocates and technology leaders, this case sets a powerful precedent—sending a clear message that abuse of digital platforms for malicious purposes will not go unchecked.
