Nationwide Healthcare Data Breach: Protecting Patient Information: Investigating the Breach and Identifying Measures for Safeguarding Sensitive Medical Data


In recent news, a nationwide healthcare data breach has impacted millions of patients across the country, including individuals in the Brazos Valley. Welltok, a Colorado-based healthcare platform, discovered unauthorized access to their MOVEit Transfer server, compromising sensitive patient information. While there is no evidence of misuse, it is essential for affected individuals to take proactive steps to protect their personal information. This article provides a comprehensive overview of the data breach, the information that may have been compromised, and the actions individuals can take to safeguard their data.

What Happened?

Welltok first became aware of the potential compromise on July 26, 2023, when they were alerted to software vulnerabilities in their MOVEit Transfer server. Despite having installed all published patches and security upgrades promptly, an unauthorized actor exploited these vulnerabilities on May 30, 2023. The breach resulted in the exfiltration of certain data from the server.

After an extensive investigation conducted by third-party cybersecurity specialists, Welltok confirmed the presence of data related to certain individuals on the impacted server. The compromised information may include names, addresses, phone numbers, email addresses, and, in some cases, more sensitive data such as social security numbers, Medicare or Medicaid ID numbers, and specific health insurance information. It is important to note that Welltok has not found any indication of misuse of this information thus far.

Protecting Yourself from Identity Theft and Fraud

While there is no evidence of misuse of the compromised information, it is crucial to remain vigilant against identity theft and fraud. Here are some steps you can take to protect your personal information:

  • Review Account Statements: Regularly review your account statements and explanation of benefits forms for any suspicious activity. Report any discrepancies or unauthorized transactions immediately to the relevant financial institutions or healthcare providers.
  • Monitor Credit Reports: Obtain your free credit reports annually from each of the three major credit reporting bureaus (Equifax, Experian, and TransUnion). Monitor these reports for any unusual activity or errors. You can request a free credit report at or by calling 1-877-322-8228.
  • Fraud Alerts: Consider placing a fraud alert on your credit file. An initial fraud alert lasts for one year and requires businesses to verify your identity before extending new credit. If you are a victim of identity theft, you can request an extended fraud alert that lasts for seven years.
  • Credit Freezes: Another option is to place a credit freeze on your credit report. This restricts access to your credit information, making it difficult for fraudsters to open new accounts in your name. Keep in mind that a credit freeze may delay or interfere with legitimate credit applications.
  • Stay Informed: Educate yourself about identity theft, fraud alerts, and credit freezes. Familiarize yourself with your rights under the Fair Credit Reporting Act (FCRA) and the steps you can take to protect your personal information. The Federal Trade Commission (FTC) provides valuable resources on their website (
  • File Complaints: If you believe your information has been misused, file a complaint with the FTC and local law enforcement. You may also contact your state Attorney General’s office to report instances of known or suspected identity theft.
