A judge is allowing the state Revenue Department to notify banks and credit unions of the 3.3 million bank account numbers compromised when someone hacked department tax files.
The banks will be able to determine which customers' accounts may be at risk.
The state and banks needed a judge's permission to release the information. A judge in Richland County approved the release in an order this week.
Gov. Nikki Haley says that taxpayers will start receiving notification letters next week if their personal financial data was stolen in massive cyber-attack thought to be the largest ever at a state agency.
Haley spokesman Godfrey says the governor's office worked with the banks to get the information released to the banks.
