A ransomware attack targets a small-to-medium-sized hospital in the U.S. following the expiration of CISA 2015, which crippled its threat intelligence-sharing capabilities. The hospital, lacking real-time warnings about emerging ransomware variants, falls victim to a life-threatening cyberattack that encrypts critical systems including patient records, surgical schedules, and emergency response protocols. The attack forces a delay in time-sensitive treatments (e.g., cancer therapies, surgeries) and diverts ambulances to other facilities, directly endangering patient lives. Studies cite 42–67 Medicare patient deaths linked to similar ransomware incidents (2016–2021). With systems locked for 3–4 weeks, the hospital faces $432,000+ in ransom demands and operational losses, risking permanent closure. The breach also exposes patient PII/PHI, triggering HIPAA violations and reputational collapse. The attack exploits the gap in government-industry threat sharing, proving how CISA 2015’s lapse turns hospitals into high-value, low-defense targets for cybercriminals prioritizing speed over stealth.
