The ABC can reveal that sensitive medical data of nearly one in two Australians, stolen from e-scripts provider MediSecure, is now listed as 'sold' on the dark web. The company announced last week that 12.9 million people had been exposed in the breach, which occurred last year. Now, an online listing indicates that not only has the data been sold, but it is being offered a second time at the reduced price of $25,000.
