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.
Anyone who has filed a South Carolina tax return since 1998 — including former residents who have since moved out of the state — is being urged to call (866) 578-5422 to enroll in a consumer protection service and visit protectmyid.com/scdor.
