Cyber Threats and Attacks

Cyber threats and attacks are hostile actions against computer systems and data, including ransomware, data theft, espionage, and disruption of services. Criminals, foreign governments, and other groups carry them out. Federal law enforcement, intelligence agencies, and the Cybersecurity and Infrastructure Security Agency work to counter them.

People usually ask who is behind attacks, how they reach government and business networks, and which agency has responsibility when one occurs. They also ask how supply chains become a path for attackers and how the government shares warnings with the public.
