The FBI’s cyber strategy imposes risk and consequences on cyber adversaries. Malicious cyber activity threatens the public’s safety and national and economic security. Our goal is to change the behavior of criminals and nation-states who believe they can compromise U.S. networks, steal financial and intellectual property, and put critical infrastructure at risk without facing risk themselves. To do this, we use our unique mix of authorities, capabilities, and partnerships to impose consequences against our cyber adversaries.
The FBI is the lead federal agency for investigating cyber-attacks and intrusions. We collect and share intelligence and engage with victims while working to unmask those committing malicious cyber activities, wherever they are.
