One of the largest private health insurers in Australia, the Medibank Group serves more than 3.9 million individuals through its Medibank and ahm brands.
Initially identified on October 12, the unusual activity was “consistent with the precursors to a ransomware event”, resulting in the company taking some systems offline, to contain the threat.
“Our ahm and international student member services and policy management systems have been taken offline. This will cause disruptions for some of our customers,” Medibank announced on Tuesday, adding that phone support is still available for the affected customers.
