How Did the Breach Occur?

The MCNA data breach occurred because the Bitlocker ransomware gang broke into the company's computer systems and gathered a substantial amount of data from the company. The attackers asked for a $10 million ransom and began leaking a small portion of the stolen data across the dark web.

When Did This Breach Occur?

This MCNA data breach was first detected on March 6, 2023, but it actually occurred from February 26, 2023, until March 7, 2023. After those dates, the company locked down the network and hired cybersecurity specialists to investigate the issue and determine how the attack occurred and what data was taken.

Who Does the Breach Impact?

This MCNA data breach affects nearly 9 million patients, guardians, parents, and guarantors that rely on MCNA in one way or another. If your data was kept with the organization, you may have been exposed to this breach.

How Many Files Does the Breach Affect?

The total MCNA file count exposed in this breach hasn't been disclosed. We only know that millions of people were affected by the breach, but we don't know how many documents it took to impact so many people. We suspect thousands of documents were involved in this breach, though. If you were involved in this attack, you will receive a notice informing you of the risks. You should immediately secure your credit and consider investing in a credit monitoring service to keep a close watch over your credit for long-term protection.
