Delta Dental of California Data Breach: What it Means for the Dental Industry

Data breaches have become an unfortunate reality. And, the healthcare industry has been a prime target for cybercriminals due to the sensitive nature of patient data. In June 2023, Delta Dental of California discovered a data breach that affected approximately 7 million patients. In this article, we dive into the details of the breach and its implications for dental professionals.

What Happened in the Delta Dental of California Data Breach?

The Delta Dental of California data breach was caused by a hacking group’s exploitation of a zero-day vulnerability in Progress Software’s MOVEit Transfer solution. The incident exposed sensitive patient information (financial account numbers, credit/debit card numbers – including security code, access, code, password or PIN for the accounts), of approximately 7 million individuals – making it one of the most significant healthcare data breaches in recent years.

An unknown vulnerability in MOVEit, a widely used file transfer system, has had far-reaching implications, affecting thousands of organizations globally, not just Delta Dental of California. This breach has underscored the persistent threats lurking in even the most seemingly secure systems. 

MOVEit, like many other data transfer systems, is designed to be a secure way to transfer sensitive files; but the breach has proven that even such systems can have vulnerabilities exploited by determined cybercriminals. The exact nature of the vulnerability has not been shown to avoid misuse, but this incident is a reminder for all organizations to stay vigilant and constantly update their data security measures.
