COLUMBIA, S.C. (AP) — The company doing credit monitoring for South Carolina residents affected by a data breach signed a $12 million contract to work with the state just two days after being called, a representative told state lawmakers Thursday.

Mark Kapczynski told a Senate panel probing the state’s cyber security that Experian was called on Oct. 23 by an attorney whose firm was hired by the Department of Revenue after state officials learned that millions of taxpayers’ data had been accessed. On Oct. 25, Revenue Director Jim Etter signed an initial agreement, which was subsequently amended and then signed again Nov. 9.
