Ransomware is a malicious software that encrypts files and leaves data and systems unusable. With ransomware attacks, hackers gain entry into a system, lock out users, and demand payment to regain access.

Homeland Security, FBI, and Secret Service help state, local, and other governments prevent or respond to ransomware attacks on systems like emergency services. Most government entities said they're satisfied with the agencies' prevention and response efforts. But many cited inconsistent communication during attacks as a problem. We recommended that the federal agencies address cited issues and follow key practices for better collaboration.
