Massachusetts hospital discovered a data breach 14 years after receiving a complaint from a former patient. Tewksbury Hospital learned of the breach in the spring of 2017. The hospital has provided written notice to affected patients for whom the hospital has current contact information. It hasn’t found any evidence to suggest the security incident resulted in attackers misusing patients data. Some 1,100 patients whose personal and medical data the breach might have exposed may have been exposed. Those affected should watch their credit reports carefully for suspicious activity.”]
