(Reuters) -Medibank Private Ltd was slapped with a second class action lawsuit related to its disclosures on its cyber security systems leading up to a data breach last year, Australia's largest health insurer said on Wednesday.

Last October, Medibank disclosed that a hacker had gained data of 9.7 million current and former customers and released the data on the dark web.
