One of the largest data breaches in US history has occurred and this is how to check if you've been affected

The Conduent data breach is one of the largest in US history, with more than 25 million people affected – and here’s how to check if you’re one of them.

Conduent is a company that handles data for healthcare providers, numerous corporations, and state agencies. 

The company identified a cyberattack in January 2025, with hackers gaining unauthorized access between October 21, 2024, and January 13, 2025. 

Earlier this month, it was reported that more than 15 million could be affected by the data breach, but this number has since been revised to over 25 million.

How to find out if you’ve been affected by the Conduent data breach

In a statement Conduent said compromised data ‘may have included name, social security number, medical information, and health insurance information’, but added that ‘not every data element was present for every individual’. 

The breach is considered to be particularly concerning as it involves sensitive personal and medical information, rather than just credit or debit card numbers. 

The data breach will impact numerous states, and is one of the largest in US history. 

Conduent has said it will notify those affected by the middle of April.

“Conduent has agreed to send notification letters, on behalf of its clients, to individuals whose personal information may have been affected by this incident,” the company told Fox New’s Cyberguy. 

“Working in conjunction with our clients, we expect to send out all of the consumer notifications by April 15. 

“In addition, a dedicated call center has been set up to address consumer inquiries. At this time, Conduent has no evidence of any attempted or actual misuse of any information potentially affected by this incident.”

What should you do if you are affected?

If you are notified that your information has been accessed in the Conduent data breach, then it’s a good idea to start closely monitoring your financial accounts and check your credit reports regularly. 

You can also place a credit freeze on your account, to stop anyone from opening new accounts in your name without your permission. 

Set up two-factor authentication wherever possible, and change your email password. 

If you share passwords across multiple sites and services, it’s a good idea to change those and consider getting a password manager to help keep things safe.
