The breach occurred when Systema Software — a California company that provides claims-administration software to government agencies and private clients to handle worker compensation and auto and property insurance claims — was upgrading its system.
Intermediate storage places for this data, Rowley said, were "set up improperly, and our files were available on the Web."
He said county officials responded quickly after the hacker, Chris Vickery, found them online and reported his discovery to Systema and the proper authorities. At the time, Systema said Vickery "provided written confirmation to the Texas attorney general that he has not shared or used the data inappropriately."
That prompted Councilman Richard Snelgrove to suggest the council offer an "expression of gratitude for what [Vickery] did as a public service."
As soon as the breach was discovered, Rowley said, county officials informed their cyber-insurance carrier, hired a cyber-security company called Kroll to assess the system, sent letters to victims now living in eight states and set up a call center to answer questions.
The county's investigation determined 8,000 people had their "personal identifiers and medical records" breached. Another 6,200 had only their names and contact information exposed.
The county also hired a legal expert in breaches to help it respond properly, Rowley said, noting that exposed employees will receive credit-monitoring and credit-restoration assistance.
The county has paid $88,000 to remedy the situation, mostly for the breach counsel and credit monitoring. Rowley said he expects the bottom line to "grow as people sign up for fraud monitoring — but not a lot more."
He also foresees the county receiving reimbursement for most of these expenses from the contractor.
