CareFirst BlueCross BlueShield Community Health Plan in Washington, D.C., was the victim of a data breach affecting 200,665 people and likely carried out by foreign cybercriminals.
The health plan, formerly Trusted Health Plan, said in a data notice that every current enrollee, current employee and former employee has been affected by the incident.
Seven details to know about the data breach:
