An Internet security firm said a limousine software company has been hacked, exposing credit card numbers and potentially embarrassing details about close to 1 million customers, including politicians, star athletes and corporate executives.
Alex Holden, chief information security officer of Milwaukee-based Hold Security, said Monday he discovered the breach at Corporatecaronline and informed its owner more than a month ago.
Holden says customers' credit card numbers, pick-up and drop-off information and other personal details had been stolen.
Corporatecaronline is a limousine software company based in Kirkwood, Mo. Car services buy the software and use it to streamline reservations, dispatching and payments. Owner Dan Leonard didn't return a call for comment.
