The Advanced Research Projects Agency for Health (ARPA-H) is joining forces with the Defense Advanced Research Projects Agency (DARPA) to expand the Artificial Intelligence Cyber Challenge (AIxCC). Cyber and ransomware attacks on America’s health care systems have increased significantly in recent years, often preventing patients from receiving care and compromising their personal information . By collaborating with DARPA on the AIxCC, ARPA-H aims to spur the development of AI-enabled technology to safeguard hospitals, pharmacies, and medical devices from cyberattacks.
