Motives Behind the Attack: Unraveling the Why

The question of why hackers targeted Medibank in a cyber attack remains a mystery. However, experts believe that the healthcare industry has become a prime target for cyber criminals due to the sensitive nature of patient information and the value it holds on the black market.

“Healthcare data is more valuable than any other personal data; it includes names, addresses, medical records, and financial information. All of this can be used for identity theft, insurance fraud, and other crimes,” says James Scott, Sr. Fellow, Institute of Critical Infrastructure Technology.

The motive for the Medibank breach might have been financial in nature, given the potential for lucrative returns on the sale of stolen patient information. Alternatively, it could have been politically motivated, seeking to disrupt healthcare services or gain an advantage in negotiations.

Another theory is that the hackers were looking to exploit vulnerabilities in Medibank’s cybersecurity defenses to gain access to more valuable targets. This “island hopping” technique has been used in previous cyber attacks on large corporations.

Whatever the motive, the Medibank breach serves as a sobering reminder of the continued threat of cybercrime in the healthcare industry. It highlights the need for robust cybersecurity measures and proactive threat intelligence to protect patient data and prevent future breaches.

Case Study: Anthem Data Breach

The Anthem data breach in 2015 was one of the largest healthcare data breaches in history, affecting over 78 million customers. The breach was traced back to a Chinese hacker group, believed to be operating on behalf of the Chinese government.

The motive for the attack was unclear, but the stolen data included sensitive personal information such as names, addresses, social security numbers, and medical records. The breach resulted in a $115 million settlement with affected customers and highlighted the need for stronger cybersecurity measures in the healthcare industry.
