Medical records, SSNs, and bank details exposed in CareCloud data breach

Healthcare technology giant CareCloud has confirmed that a data breach earlier this year impacted more than 3.75 million people, making it one of the largest healthcare data incidents disclosed this year.

The New Jersey-based company, which provides electronic health record (EHR) and practice management services, first flagged the intrusion in an SEC filing back in March, but the true scope only became clear this month when the Department of Health and Human Services (HHS) breach tracker updated the affected total from roughly 345,000 to 3,756,469 individuals.

CareCloud says an unauthorized third party accessed one of its Amazon Web Services (AWS) environments between March 10 and March 16, 2026. The intrusion caused an eight-hour disruption to one of the company’s six EHR environments before systems were restored that same evening. During a forensic investigation, CareCloud determined that the attacker claimed to have exfiltrated data from databases within that environment.

The stolen data reportedly includes both identity and medical information:

• Full names, postal addresses, and dates of birth
• Social Security numbers (SSNs) and driver’s license or passport numbers
• Medical records and health insurance information
• Bank account and financial details, plus full credit card data (including CVV) for a limited subset of victims

What affected customers should do

Anyone receiving a breach notification letter should take it seriously, given the combination of medical, identity, and financial data involved.

If you think you’ve been affected by a data breach, here are steps you can take to protect yourself:

• Check the company’s advice. Every breach is different, so check with the company to find out what’s happened and follow any specific advice it offers.
• Change your password. You can make a stolen password useless to thieves by changing it. Choose a strong password that you don’t use for anything else. Better yet, let a password manager choose one for you.
• Enable two-factor authentication (2FA). If you can, use a FIDO2-compliant hardware key, laptop, or phone as your second factor. Some forms of 2FA can be phished just as easily as a password, but 2FA that relies on a FIDO2 device can’t be phished.
• Watch out for impersonators. Cybercriminals may contact you posing as the breached company. Check its official website to see if it’s contacting victims, and verify the identity of anyone who contacts you using a different communication channel.
• Take your time. Phishing attacks often impersonate people or brands you know and use themes that require urgent attention, such as missed deliveries, account suspensions, and security alerts.
• Consider not storing your card details. It’s definitely more convenient to let sites remember your card details, but it increases the risk if a company suffers a breach.
• Set up identity monitoring. This can alert you if your personal information is found being traded illegally online and help you recover afterward.
