SYDNEY (Reuters) -Australia's biggest health insurer said on Thursday a criminal had apparently stolen customers' medical information as part of a massive breach of data, fuelling concern about a wave of high-profile cyber attacks.

Medibank Private Ltd, which covers one-sixth of Australians, said an unidentified person had shown the company stolen personal information of 100 customers, including medical diagnoses and procedures, as part of a theft of 200 gigabytes of data, first disclosed by the company a week earlier.
