MCNA has released a notice informing insurance holders of a data leak affecting nearly 9 million individuals across the United States.
Managed Care of North America, Inc (MCNA) and their partner, MCNA Dental, have notified users and the Attorney General of Maine regarding a large data breach that occurred between February 26th and March 7th of 2023.
In the notification to the Attorney General, MCNA’s counsel said that up to 8,923,662 individuals were affected, including those living in the District of Columbia, Iowa, Maine, Maryland, New Mexico, New York, and North Carolina. The notification also stated that MCNA discovered the breach on May 3rd.
In the notice of data breach to users, MCNA said personal information, like social security numbers, driver’s license numbers, and more, was stolen alongside personal health information, including care for teeth and insurance claims.
LockBit, a large ransomware group, took responsibility for the attack and threatened to publish all materials if a $10 million ransom wasn’t paid. The stolen materials were published on LockBit’s leak site on April 7th.
In response, MCNA is offering identity theft protection services, including credit monitoring and more.

In their online statement, the MCNA team said that once they learned about the data breach, they “immediately began an investigation. Law enforcement was contacted. We are also making our computer systems even stronger than before because we do not want this to happen again.”
In the FAQ section, the MCNA team also stated that the notification was delayed because of the complexity of the breach, “it was important that a thorough investigation into the matter took place to confirm what happened, and identify those individuals who may have been impacted.”
The MCNA data breach follows the breach of PharMerica, a pharmacy service company, that also took place in March. According to their report, nearly 6 million individuals were affected in this data leak.
