As many as 3.6 million Social Security numbers and 387,000 credit and debit card numbers used by state taxpayers could have been exposed to a hacker in recent cyber attacks on the state Department of Revenue's computers, officials said on Friday.

The vast majority of the credit card numbers used by South Carolina taxpayers were encrypted, but about 16,000 were not, meaning the data was fully exposed, state police said.

None of the Social Security numbers were encrypted, said State Law Enforcement Division spokesman Thom Berry. Berry said the hacker used a foreign Internet Protocol (IP) address to gain access to the data.
