Overview
This report states nearly eight times as many current and former Energy Department staff members were affected by a July computer hack than was previously estimated, according to the agency's inspector general. In August 2013, DOE estimated that the hack affected roughly 14,000 current and former staff, leaking personally identifiable information such as Social Security numbers, birthdays, and banking information. But the breach apparently affected more than 104,000 people.
