100 Million Affected In Massive Healthcare Data Breach

Table of Contents

Change Healthcare, a UnitedHealth Group subsidiary, processes around 40% of global medical bills—about 15 billion invoices and claims. Now, this large company has experienced a Ransomware attack, and the consequences are emerging.

In late February 2024, the ALPHV/BlackCat Ransomware group hacked Change Healthcare, a part of UnitedHealth Group. They disrupted operations and stole up to 6TB of data, including personal details, payment info, insurance records, and other sensitive data. A ransom payment of $22 million was reportedly made, but it’s not confirmed.

Only in October 2024, Change Healthcare reported that about 100 million people had their personal, financial, and medical data exposed in a breach.1

This is now the largest healthcare data breach reported to federal regulators, surpassing the previous record set by Anthem’s 2015 breach, which affected 78.8 million people.2

Change Healthcare Breach Triggers OCR Investigation

Change Healthcare initially notified the Department of Health and Human Services’ (HHS) Office for Civil Rights (OCR) of a Cyberattack using a placeholder estimate of 500 affected individuals, as the investigation was still ongoing when the report was submitted on July 19, 2024.

Recently, Change Healthcare updated OCR, confirming that approximately 100 million individuals have been notified of the breach. At this time, neither Change Healthcare nor UnitedHealth Group (UHG) has confirmed if the file review is complete.

OCR has launched an investigation to assess Change Healthcare’s HIPAA compliance before the attack. Due to the unprecedented scale, this inquiry may take months or even years. 

However, a Ransomware attack and data theft do not automatically indicate Health Insurance Portability and Accountability Act (HIPAA) noncompliance. However, if noncompliance is found, a financial penalty may be imposed. 

Out of 3,400 breaches of 500+ records listed in OCR’s portal, only 149 resulted in financial penalties for noncompliance. The maximum penalty for a HIPAA violation under the Health Information Technology for Economic and Clinical Health (HITECH) Act is $1.5 million, or just over $2.1 million when adjusted for inflation, applied per violation per year, according to a post by Steve Adler, editor of The HIPAA Journal.

What The Change Healthcare Breach Means For You

In this data breach, a wide range of personal information may have been exposed, including:

  • Personal Details: Names, billing addresses, Social Security numbers, birth dates, and ID numbers (driver’s licenses, state IDs, and passports).
  • Insurance Information: Health plans, policy details, insurance member/group IDs, Medicaid, and Medicare ID numbers.
  • Billing Information: Billing codes, account numbers, and potentially credit card information.
  • Medical Records: Sensitive medical data, including diagnoses, test results, provider information, appointment dates, and prescription history.

The exposure of medical records may be the most troubling aspect of this breach. Unlike credit cards or addresses, your medical history and biometric data are permanent, which makes them highly valuable on the dark web. 

Cybercriminals use this data for identity theft, extortion, and fraudulent medical or insurance applications. Unlike other personal data, stolen medical information has a long shelf life for misuse, presenting ongoing risks for those affected.

Survey Reveals Widespread Impact of Change Healthcare Breach

The American Medical Association (AMA) conducted a survey that shows the extensive disruption caused by the Change Healthcare breach:

  • 36% of practices had claims payments suspended
  • 32% couldn’t submit claims
  • 39% lacked access to electronic remittance advice
  • 77% experienced service disruptions
  • 80% lost revenue from unpaid claims
  • 78% lost revenue from unsubmitted claims
  • 55% used personal funds to cover expenses

Nearly half of respondents had to work with costly new clearinghouses for electronic transactions. While some practices received advance payments and temporary assistance, issues remain. The survey also included feedback from affected physician practices. UnitedHealth Group reported paying over $2B to help affected providers.

Protection Measures Amidst Fallout of Change Healthcare Breach

If your information was compromised by the Change Healthcare breach, it’s important to take immediate action to protect your identity. Start by enrolling in credit monitoring services, which can help detect any fraudulent activity. Change Healthcare is offering these services, but you may also consider additional tools. 

Update your passwords, especially for sensitive accounts like banking and healthcare, and enable multi-factor authentication (MFA) where possible. The Change Healthcare Cyberattack was caused by the lack of MFA on a legacy server. Notify your financial institutions of the breach, and monitor your accounts for any unusual transactions.

FAQ

What Happened In The Change Healthcare Cyberattack?

In the Change Healthcare Cyberattack, hackers gained access to sensitive data due to a lack of proper security measures on an old server. This led to disruptions in healthcare services, stolen personal information, and financial losses for many providers. The attack affected hospitals and healthcare organizations across the country, including 100 million individuals.

Who Targeted Change Healthcare?

The Change Healthcare cyberattack was carried out by the ALPHV/BlackCat Ransomware group. This group uses malicious software to steal data and demand ransom payments. They targeted Change Healthcare’s systems to access personal information and disrupt healthcare services, causing widespread issues across hospitals and healthcare providers.

What Are The Consequences Of Cyberattacks In Healthcare?

Cyberattacks in healthcare can lead to stolen personal data, service disruptions, and financial losses. They can also damage a healthcare organization’s reputation and trust. To prevent this, the 2Secure team recommends using MFA to strengthen login security, regular backups and recovery plans to protect data, and endpoint protection to defend against threats on all devices. Since the Change Healthcare systems suffered from a Ransomware attack, it would be ideal to also set up an attack simulation to prevent such incidents.
