Medibank Data Breach
The Medibank data breach in 2022 was another significant incident. Hackers infiltrated the health insurer's database, compromising the personal health information of around 10 million customers. This breach not only risked the privacy of sensitive health data but also posed potential threats to the financial standing and mental health of those affected.
Latitude Financial Breach
In March 2023, Latitude Financial suffered a data breach that impacted over 14 million customers in Australia and New Zealand. Hackers gained access to employee login credentials, which they used to steal personal data from third-party service providers. This breach underscored the importance of robust cyber security measures and the potential risks associated with third-party services.
Impact of Cyber Security Breaches on Individuals and Corporations
Financial Consequences
Cyber security breaches can lead to severe financial losses for both individuals and corporations. Victims may face direct financial loss due to stolen credit card information or fraudulent transactions.
