"This is not a good day for South Carolina." That was Governor Nikki Haley's public reaction to news that a foreign hacker had infiltrated South Carolina's Department of Revenue and made off with 3.6 million social security numbers and 387,000 credit/debit card numbers. Of the compromised cards, state officials believe only 16,000 were unencrypted, though the staggering social security breach affects more than half of South Carolina's 4.6 million population. Governor Nikki Haley held a presser earlier this afternoon confirming the attack — first uncovered by WLTX Columbia. “The number of records breached requires an unprecedented, large-scale response by the Department of Revenue, the State of South Carolina and all our citizens,” said Haley before outlining steps that residents can take to discover if their information was exposed.
