The state attorney general's office is warning that callers are targeting 3.2 million Texans who had Social Security numbers and other personal information inadvertently exposed to the public.
Texas Attorney General Greg Abbott says investigators have received reports of victims of the security leak receiving calls at home asking to confirm Social Security numbers.
On Tuesday, Abbott said the callers claim to represent one of three state agencies whose employees or retirees had their information exposed, but none of the agencies are actually making such calls.
The FBI and Abbott's office are investigating after personal data was left for a year, and in some cases even longer, on a Texas comptroller's office server that was publicly accessible.
Four comptroller's office personnel involved have been fired.
