“We are currently experiencing higher than normal call wait time. Please call back at a later time or date. We apologize for any inconvenience.”

That’s the message you’ll get if you try calling the toll-free number of Experian in order to find out if you’re one of 3.6 million South Carolina taxpayers whose Social Security numbers were stolen in a cyber attack. According to the Post and Courier, 387,000 credit and debit card numbers were also exposed to the overseas hacker. State officials revealed the attack in an announcement made earlier today.

The P&C reports that anyone who has filed a South Carolina tax return since 1998 is a possible victim.

According to Columbia’s WTLX:

The first breach occurred on August 27, 2012 although we are told no information was taken at that time. On October 10, the SC Division of Information Technology informed the Dept. of Revenue of a potential cyber attack. On October 16, investigators uncovered two attempts to probe the system from September. In mid-September, two other intrusions occurred, and the hacker got data for the first time.

To determine if you’re one of the unlucky 3-plus million, you must call the toll-free number, (866) 578-5422 or log in to protectmyid.com/scdor. However, in order to log in to the site, you need a redemption code — which you can only get by calling the clogged up toll-free number.

Reassuring, isn’t it?
