A sophisticated cyber attack against the Thrift Savings Plan contractor responsible for maintaining the agency’s data centers compromised the information of 123,000 TSP participants.
Of the compromised accounts, about 43,000 had personal information, such as names, Social Security numbers and bank-account numbers exposed. Another 80,000 compromised accounts had only Social Security numbers and other TSP-related information exposed.
