COLUMBIA, S.C. (AP) — Six months after a hacker stole the personal data of millions of South Carolina taxpayers, legislators are moving past finger-pointing hearings on who to blame and focusing on how to prevent another massive breach.

Meanwhile, the cost to taxpayers continues to climb. The mid-September cybertheft of unencrypted data from the Department of Revenue’s servers represented the nation’s largest hacking of a state agency. The cleanup since state officials learned of the breach Oct. 10 from the U.S. Secret Service has cost $25 million so far.
