CHICAGO — A company that manages parking garages in Chicago and other cities said customer data at 10 local garages has been affected by a data breach.
SP+ announced Friday the company that manages some of its payment card systems found "an unauthorized person used that company's remote access tool to connect to computers that process payment cards" in some of its locations.
Ten parking garages in Chicago and three in Evanston were affected, the company said. Other cities that saw data breaches were Cleveland, Philadelphia and Seattle. In all, 17 locations were affected.
The earliest data could have been breached in Chicago is Sept. 29; in Evanston, Oct. 8.
SP+ began an immediate investigation and hired a computer forensic firm to study the breaches, it said. SP+ said data at risk from malware installed on its servers may include a cardholder's name, card number, expiration date and verification code.
The company said the malware has since been disabled, and is working with credit card companies to learn which accounts may be at risk.
"If a customer used his or her card at one of these locations between the earliest and last at risk dates, the customer should review his or her account statements for any unauthorized activity regularly," the company said in a statement.
If a customer notices unauthorized charges, the company said to contact the bank that issued the card. Credit card companies typically guarantee cardholders are not responsible for fraudulent charges.
