Secret CISO 5/3: UnitedHealth and Verizon Data Breaches, ClubNSW Leak, North Korean Hackers, and Critical Vulnerabilities in R Language

Good morning, Secret CISO readers! Today's newsletter is packed with the latest news and insights from the world of cybersecurity. First up, we delve into the recent UnitedHealth data breach, which exposed sensitive patient data to the open internet. This incident serves as a stark reminder of the vulnerabilities in our healthcare systems and the urgent need for robust security measures. Next, we examine the human element in cyber threats, as highlighted in Verizon's 2024 Data Breach Investigations Report. The report reveals how human error continues to play a significant role in data breaches, emphasizing the importance of ongoing security education and awareness. In other news, a major data breach has impacted the Airsoft community site, exposing the sensitive data of 75,000 individuals.

Meanwhile, a man has been charged over a ClubNSW data breach, which exposed the driver's licenses of over 1 million Australians. We also explore how 68% of data breaches occur due to social engineering attacks, according to GBHackers. This highlights the need for organizations to prioritize security training and awareness among their employees.

Finally, we look at the latest cybersecurity research and vulnerabilities, including a critical flaw in the R Language that poses a supply chain risk, and a security expert who was awarded $250,000 for uncovering a major flaw in DeFi Protocol Curve Finance. Stay safe and stay informed!
