Attackers had two months of unfettered access to South Carolina s Department of Revenue systems in a classic targeted attack. Payment card and personal information on 3.8 million filers, possibly dating back to 1998, was stolen in the attack. Governor Nikki Haley said her administration could have done more to prevent the breach. Haley said an encryption deployment is under way and that she has contacted the IRS urging them to re-examine their stance on encryption. More than 74 GB of data were stolen, including 23 database backup files.
