Signature Healthcare in Massachusetts was forced to divert ambulances and shut down some services after a cyberattack disrupted operations at its two hundred-bed Brockton Hospital and medical group serving over one hundred fifty physicians. While emergency walk-in services remained open and surgeries continued, chemotherapy treatments were canceled and retail pharmacies couldn't fill prescriptions, though no ransomware group has yet claimed responsibility for the attack. The incident highlights the ongoing vulnerability of healthcare systems to cyberattacks, which have impacted facilities worldwide and in some cases been linked to patient deaths.
