A major ransomware attack has disrupted multiple hospital systems across the United States, triggering delays and operational strain as healthcare providers work to restore access to critical services. The incident began late Friday and quickly spread across facilities, according to Reuters.

Attackers behind the campaign are demanding ransom payments in cryptocurrency, a tactic that has become common in high-impact cyber extortion cases. While the full scale of the breach is still being assessed, the immediate effect has been service interruptions at hospitals that rely on digital systems for scheduling, records, and internal communications.

The attack adds to growing concern over the vulnerability of healthcare networks, which remain attractive targets because of the urgency of patient care and the sensitivity of medical data. Cybersecurity experts have repeatedly warned that hospitals are often forced to choose between paying criminals and absorbing costly disruption.

Officials and technical teams are still working to contain the damage and determine how the intrusion was carried out. The incident underscores the need for stronger defenses across the healthcare sector as ransomware groups continue to exploit weak points in critical infrastructure.
