(CNN) A cyberattack on a contractor used by the International Committee of the Red Cross (ICRC) has compromised the personal data of more than 515,000 "highly vulnerable people," including people separated from their families by conflict and disaster, the organization said Wednesday. It's unclear who was responsible for the cyber incident, but the Red Cross said its "most pressing concern" was the potential for the compromised data to be leaked. There is no indication that has happened yet, according to the Red Cross. The hack hit a Switzerland-based firm that the Red Cross pays to store its data, the humanitarian organization said without naming the firm. The compromised data came from at least 60 of the "national societies," or networks of volunteers and staff, around the world that the Red Cross uses as first responders to disasters.
