Beacon Health Systems fell victim to a "sophisticated cyber attack," but the health agency says it hasn't found evidence of information being misused. The breach allowed unauthorized individuals to gain access to Beacon employee email boxes, which exposed personal and protected health information of some individuals, including patients, according to a news release. Beacon began mailing letters to affected individuals Friday. But Beacon, which oversees Memorial Hospital in South Bend and Elkhart General Hospital, said there "is no evidence of any actual or attempted misuse of personal or protected health information belonging to Beacon Health System patients."
