Cyberattacks pose a serious threat to US national security by targeting critical systems, sensitive data, and national infrastructure. Government networks, military operations, power grids, financial institutions, and healthcare systems are increasingly vulnerable to cyber intrusions. Hackers can steal classified information, disrupt essential services, or manipulate data, weakening public trust and national stability. In the middle of these challenges, US national security threats are amplified by state-sponsored cyber warfare, where hostile nations use digital attacks to gain strategic advantages without direct military conflict. Cyberattacks can also interfere with elections, spread misinformation, and damage economic competitiveness. As technology becomes more integrated into daily life, the scale and impact of cyber risks continue to grow. Protecting against these threats requires strong cybersecurity policies, international cooperation, skilled cyber defense teams, and constant innovation to safeguard national interests and long-term security.
