The company issued an official statement apologizing for the temporary outage and confirming that a ransomware attack had occurred, and informed customers that business as usual had been resumed.
David Koczkar states that although the business was the victim of a ransomware attack, no systems were encrypted. Additionally, even though they are still looking into the incident, there is no proof that the attackers stole any customer data.
According to Bleeping Computer, on October 12th, the company discovered unusual activity on its network and immediately shut down some of its systems, including services geared toward customers, to minimize the risk of data loss in the event of a cyberattack.
On the 14th of October, about 2.8 million emails and SMS were sent out by Medibank to inform its clients of the security breach and to explain the reasons behind the outages.
