Have you been affected by Ciox Health LLC, d/b/a Datavant Group's data breach?

A recent data breach at Datavant has compromised the personal information of nearly 50,000 individuals, including minors. The breach came to light through a filing with the Maine Attorney General, revealing that unauthorized access had compromised sensitive data.

Although there is no confirmed evidence of misuse at this time, affected individuals are encouraged to stay vigilant. It’s recommended to closely monitor financial accounts, update passwords, and be cautious of potential phishing attempts. For guidance on safeguarding your information after this incident, explore this resource on how to take action after a data breach and minimize potential harm.

Extent of  the Datavant Breach

The breach affected a total of 49,454 individuals, with only 17 being Maine residents. The compromised data was contained in a single user’s email mailbox, allowing an unauthorized individual to gain access between May 8 and May 9, 2024. Alarmingly, the compromised data primarily belonged to minors, raising concerns about identity theft and fraud risk.

Following the breach, Datavant promptly initiated an investigation with the assistance of a forensic security provider, which concluded on August 8, 2024. The company has since reinforced its cybersecurity defenses and enhanced phishing awareness training for employees. Additionally, Datavant has partnered with Kroll, a global risk mitigation firm, to provide affected individuals with two years of complimentary Minor Identity Monitoring, Fraud Consultation, and Identity Theft Restoration services.

What Information Was Involved?

The data potentially affected includes some or all of the following: Social Security numbers, financial account information, driver’s licenses, passports, health information, account credentials, and digital signatures. The information varied among impacted individuals.

How to Know if You Were Affected

If you received a data breach notification from Datavant, your personal information may have been compromised. While most victims are officially informed via a ‘‘notice of data breach” in the mail, the consequences—such as fraudulent transactions and identity theft—can begin long before you receive the notice.

Steps to Take If You Were Affected by the Datavant Data Breach

Stay Alert for Phishing Scams

Scammers may try to take advantage of the data breach by posing as the Datavant. Be wary of unexpected emails, texts, or phone calls requesting personal information. When in doubt, verify any communication directly with the company through official channels.

Monitor Your Credit and Financial Accounts

Keep a close eye on your bank statements, credit card activity, and credit reports for any unauthorized transactions. Set up account alerts to catch suspicious activity early. Take advantage of free credit reports and review them carefully for unfamiliar accounts or discrepancies.

Consider Freezing Your Credit

For added protection, request a credit freeze from all three major credit bureaus. This prevents anyone from opening new accounts in your name while still allowing you to use your existing credit. If you need to apply for credit, you can temporarily lift the freeze when necessary.
