If you live in South Carolina, there's a very good chance that slipshod state government security has allowed an overseas computer criminal to acquire your Social Security number.

The South Carolina Department of Revenue acknowledged the massive electronic security breach today, saying an electronic intrusion led to 3.6 million Social Security numbers being stolen. The state's population is approximately 4.7 million.

"We are taking immediate steps to protect the taxpayers of South Carolina, including providing one year of credit monitoring and identity protection to those affected," Gov. Nikki Haley said in a statement.
