NSO Lawsuits Expose WhatsApp’s Spyware Risk: 5 Key Lessons
In 2019, a highly sophisticated cyberattack exploited a WhatsApp vulnerability, sparking a landmark case against NSO Group, an Israeli company specializing in hacking tools. Fast-forward to 2025, and the repercussions continue to unfold, shedding light on the dark world of state-sponsored malware attacks, corporate accountability, and pressing cybersecurity concerns.
The incident has galvanized human rights advocates and tech giants to push for stricter regulations on high-tech surveillance, fueling ongoing lawsuits. This article delves into five key takeaways from the NSO Group lawsuits, exploring how Pegasus spyware compromised WhatsApp, the far-reaching implications for cybersecurity, and essential steps to protect yourself in this evolving landscape.
1. WhatsApp Zero-Day Exploit: In Detail on How It Was Accomplished
In 2019, NSO Group exploited a zero-day vulnerability in WhatsApp's voice call feature to deliver the Pegasus spyware. The spyware could install itself on a victim's phone without the victim having to answer the ringing call. The malware was capable of emptying the target's messages, microphones, camera, and location data.
Court filings uncovered over 1,400 targets of politicians, activists, and journalists up to 2025, and a 2024 report by Citizen Lab confirmed NSO's clients in governments with questionable human rights track records.
2. Legal Controversies: WhatsApp v. NSO Group
WhatsApp's parent entity, Meta, sued NSO Group in 2019 for wiretapping and unauthorized access. The new case stays with some updates in 2025:
- The Sovereign Immunity Defense for NSO has been disallowed: The courts have held that private corporations cannot avail themselves of a sovereign immunity defense against hacking claims.
- Economic sanctions: The US Commerce Department has fined NSO Group $500 million and placed it on a restricted trade list.
- New EU regulations: The 2025 DSA brings stricter controls with penalties for spyware vendors.
3. The Greater Threat: Spyware in 2025
The NSO Group is just one of a growing number of spy firms. Recent stories show:
- Emergence of New Spyware Companies
- Other companies, including Candiru and Intellexa, have recently entered this business.
- iMessage & Android vulnerabilities.
- A 2025 Google Threat Report indicated that zero-click attacks increased by 40%.
- Journalists and activists are targeted more than ever.
- The Pegasus Project revealed that repression of dissidents continues.
4. What WhatsApp (and Users) Can Do Now
After the hacking attack, WhatsApp enhanced its encryption and introduced the following features:
- End-to-End Encrypted Backups (2023)
- Two-Step Verification Mandatory (2024)
- Real-Time Attack Alerts (2025)
For users, experts recommend the following:
- Turn off VoIP calls from your contacts if you do not know them.
- Update any apps you regularly use to minimize vulnerabilities. To access applications, you must employ a secondary authentication app such as Authy.
5. The Future of Digital Privacy and Regulation
The suits against the NSO Group have established a significant legal precedent:
- Firms are pushing back: Apple and Meta have started actively suing companies that make spyware.
- Government authorities are cracking down: The US, EU, and Indian governments have implemented tougher cyber laws.
Consumer consciousness is increasing. In a 2025 Pew Research survey, 72% of people now value privacy more than convenience.
Final Thoughts: Protecting Yourself in an Era of Digital Surveillance
The WhatsApp NSO Group saga reveals an important truth: no platform is ever completely secure. While current legal battles aim to promote greater accountability, everyday users must take proactive steps to protect their privacy. The threat posed by surveillance spyware is increasing, making cybersecurity not just an option but a necessity for everyone.
Employers are likely monitoring your public online activity on platforms like LinkedIn. The lingering impact of 9/11 has led to a comparison where new job interviews resemble national security checks.
Cybersecurity will soon become mandatory in certain industries, and now, more than ever, journalists, activists, and citizens must understand the implications and necessary actions to safeguard their work.
