Ransomware Attack Results in 2 Week Shutdown of Operations at TN Medical Clinic
A cyberattack on Murfreesboro Medical Clinic & SurgiCenter (MMC) in Tennessee forced the healthcare provider to completely shut down operations for around two weeks to contain to attack and restore its IT systems. It is common for healthcare organizations to perform an emergency shutdown of the network to contain a cyberattack and limit the harm caused, and to operate under emergency procedures with staff recording patient information manually while systems are out of action. Some attacks see ambulances diverted and some appointments canceled for patient safety reasons, but the disruption caused by this attack was much more extensive. The cyberattack occurred on April 22, 2023, and the network was rapidly shut down to contain the attack. Third-party cybersecurity experts were engaged to assist with the investigation and recovery from the attack.

Lehigh Valley Health Network detected the ransomware attack on February 6, 2023, and was issued with a ransom demand. The BlackCat group threatened to release the stolen data online if the ransom was not paid.
