Nevada Hit by Massive Cyberattack: State Offices, Websites, and Services Paralyzed

In the final days of August 2025, the State of Nevada (USA) has fallen victim to a large-scale cyberattack that has rendered government systems, official websites, and telephone support services inoperative. Public offices, including the Department of Motor Vehicles (DMV), have closed, disrupting essential administrative procedures for thousands of citizens. Although there is no evidence of personal data theft so far, the incident raises alarms about the vulnerability of critical infrastructures to increasingly sophisticated cyber threats.

What happened in Nevada and what is the scope of the attack?

• The attack was detected during the early hours of August 24, forcing office closures and interrupting state web pages and phone lines, such as those of the DMV and various agencies.
• The state activated its emergency protocol, placing thousands of employees on administrative leave and prioritizing the safe recovery of systems before reopening in-person services.
• Technical details have not been disclosed to protect the ongoing investigation, but government sources have described the incident as a “targeted cyberattack” with severe operational impact.
• The public has been alerted to possible scams, phishing, or extortion attempts stemming from the attack, with instructions not to share personal information with unknown senders.
• Authorities are working with federal experts, security agencies, and forensic teams to restore services and reinforce protocols.

Context: Attacks on Critical Infrastructure and Recent Precedents

• The Nevada incident is one of the most serious faced by the state government and is the first major test for its newly created Office of Information Security & Cyber Defense.
• Similar cases have crippled public services in other US regions in recent years, such as the attack on Baltimore’s 911 system (2018) and Tillamook County, Oregon (2020), reiterating the systemic risk of ransomware and other cyberattacks against critical infrastructure.
• The attack coincides with a wave of incidents targeting local and state governments, highlighting the importance of investment, proactive vulnerability management, and close public-private sector collaboration.

What Lessons Does the Nevada Attack Offer Governments and Companies?

• The interoperability and dependence on digital systems in the public sector require well-defined contingency and recovery protocols.
• Attacks on governments aim not only to steal information but also to disrupt basic services and exert reputational and social pressure to extract ransom or cause instability.
• The incident underscores the urgent need to strengthen cyber defenses, carry out frequent audits, implement network segmentation, and provide advanced cybersecurity training to public employees.
