Breach Size: 9 Million

Data Exposed: Names, addresses, dates of birth, phone numbers, email addresses, Social Security numbers, and driver’s licenses or other government-issued ID numbers, health insurance plan information and Medicaid ID numbers, along with bill and insurance claim information.

The Russian ransomware group Lockbit successfully gained access to MCNA systems and a significant amount of patients’ personal data was compromised. The group publicly disclosed all the stolen files from the data breach after their demand for a US $10 million ransom was denied by the company.

When the breach was uncovered, MCNA immediately began an investigation with law enforcement and is working to strengthen its computer systems in an effort to avoid future data breaches.

Healthcare Operator

News Coverage: Forbes

Breach Size: 11 Million+

Data Exposed: Patient names, addresses, emails, phone numbers, dates of birth, genders, service dates, appointment locations, and appointment dates.

Private sensitive patient information for over 11 million HCA Healthcare patients was compromised when hackers gained access to external storage within an email automation platform used to send patient alerts.

HCA operates more than 180 hospitals and 2,000 care locations, such as walk-in clinics, across 20 states and the U.K.

The company stated that they have “disabled user access to the storage location as an immediate containment measure and plans to contact any impacted patients to provide additional information and support, in accordance with its legal and regulatory obligations, and will offer credit monitoring and identity protection services, where appropriate.

News Coverage: The Verge

Breach Size: 30 Million+

Data Exposed: Hackers accessed a large database containing more than 30 million Microsoft accounts, emails, and passwords.

When Chinese hacking group Storm-0558 stole a Microsoft private encryption key to access email accounts of high-level government officials, they also gained access to every Microsoft application that supports personal account authentication. This includes popular Microsoft applications such as SharePoint, Teams, OneDrive, as well as any 3rd applications that support login with Microsoft functionality. The breach remained undetected for a month until an investigation began following customer-reported information.

The full impact of this incident is thought to be much larger than what Microsoft has disclosed up to this point.
