Imagine getting to a courthouse and seeing paper signs stuck to the doors with the message "Systems down." What about police officers in the field unable to access information on laptops in their vehicles, or surgeries delayed in hospitals? That's what can happen to a city, police department, or hospital in a ransomware attack. Ransomware is malicious software that can encrypt or control computer systems. Criminals who launch these attacks can then refuse to return access until they get paid.
