A sophisticated cyberattack on the computer of a third-party Thrift Savings Plan contractor compromised the personal information of tens of thousands of TSP participants.
The Federal Retirement Thrift Investment Board and Serco Inc., a contractor that provides services to the TSP, learned in April of a July 2011 attack on a Serco computer. The FBI told Serco and the board that the incident led to “unauthorized access” to accounts of as many as 123,000 TSP participants and other recipients of TSP payments.
The TSP is a 401(k)-style investment program for federal employees.
The FBI analysis determined that files accessed by the cyberattacker contained the names, addresses and Social Security numbers of more than 43,000 individuals; some of those files also contained financial account and routing numbers. Another group of 79,000 had their Social Security number and other TSP-related information taken.
