Illinois Attorney General Lisa Madigan alerted Illinois businesses and residents Tuesday to a disclosure by the Department of Homeland Security that over 1000 businesses were hit by hackers in the same types of data breaches reported by Target and other major retailers. Madigan reminded businesses that state law requires them to promptly notify customers that their personal data has been compromised in a data breach. She also urged businesses with Illinois customers to ask their IT professionals to check their point of sale systems for the types of malware the Department of Homeland Security says have been discovered. Some tips from the state on what residents can do to better protect their personal and financial information: set up transaction alerts on your accounts ; regularly review your bank and credit card statements; review your credit reports for unauthorized accounts and consider putting a security freeze on your credit.
