Payroll processing firm Ceridian Corp. accidentally leaked employee data from a New York advertising firm on a Web site, the company confirmed Thursday.
Bloomington-based Ceridian (NYSE: CEN) notified New York advertising company Innovation Interactive last week , after it learned that it had inadvertently leaked ID and bank-account data on 150 employees, company spokesman Pete Stoddart said.
Ceridian said a former employee accidentally posted the information on a personal Web site. The employee took the data by accident after leaving the company in March 2006.
Ceridian said it is offering up to two years of credit protection services for Innovation employees affected by the breach. Ceridian also said that it is not aware of any additional security breaches involving other companies.
