The Change Healthcare data breach, confirmed on October 22, 2024, by UnitedHealth, has become one of the largest healthcare data breaches in U.S. history. This cyberattack exposed the sensitive personal and health information of over 100 million individuals. It was caused by a ransomware attack on Change Healthcare, a subsidiary of UnitedHealth, in February 2024. Here, we provide a clear and comprehensive overview of the incident, its consequences, and the questions people might have.
Change Healthcare data breach: What happened?In February 2024, Change Healthcare was hit by a ransomware attack orchestrated by the ALPHV/BlackCat group. The attackers used stolen credentials to breach the company’s remote access system, which lacked multi-factor authentication (MFA). This allowed them to steal around six terabytes of data and encrypt the company’s IT systems, leading to widespread outages across the healthcare sector. The attack affected numerous healthcare facilities, including hospitals, clinics, and pharmacies, which heavily relied on Change Healthcare for processing insurance claims and other essential operations.
UnitedHealth, the parent company of Change Healthcare, admitted to paying a ransom of $22 million to the attackers for a decryptor and the promise that the stolen data would be deleted. However, the affiliates of the ransomware group claimed that they still had the data and demanded additional payment, leading to a second round of extortion attempts. This resulted in prolonged uncertainty and stress for affected individuals, healthcare providers, and patients, who were left unsure about the security of their sensitive information.
The attack also led to significant disruptions in the healthcare system’s overall functionality. The lack of access to critical systems meant that healthcare providers struggled to deliver services efficiently, and patients faced delays in receiving necessary treatments. The Change Healthcare data breach highlighted the fragility of the healthcare sector’s IT infrastructure, particularly when targeted by well-coordinated cyberattacks.
Over 100 million individuals were affected by the Change Healthcare data breach Information exposed in the Change Healthcare data breachThe data breach exposed a vast amount of personal and healthcare-related information, including:
The type of information stolen varied between individuals, and not all affected people had their complete medical history compromised. However, the sheer volume and diversity of the stolen data make this breach one of the most concerning in recent history. The potential misuse of this information poses a significant risk to individuals’ privacy, financial security, and overall well-being.
The February ransomware attack caused significant disruptions in the healthcare system. Doctors, clinics, and pharmacies faced difficulties processing insurance claims, which impacted patients’ access to pre-authorized medications and treatments. Smaller healthcare providers and rural pharmacies were especially affected, with some even facing insolvency due to the halted payments. The inability to process claims and payments in a timely manner led to severe financial strain on these smaller providers, many of whom operate on tight budgets.
The breach also highlighted vulnerabilities in healthcare data security, leading to questions about UnitedHealth’s cybersecurity practices. During a congressional hearing, UnitedHealth CEO Andrew Witty admitted that the Change Healthcare data breach could have been prevented if the company had used multi-factor authentication. Despite spending $300 million annually on cybersecurity, UnitedHealth failed to implement this basic protective measure. This failure not only allowed the attackers to gain access but also raised concerns about the effectiveness of UnitedHealth’s overall cybersecurity strategy.
The Change Healthcare data breachhas also led to increased scrutiny from regulators and lawmakers. The U.S. Department of Health and Human Services (HHS) and other regulatory bodies have launched investigations into UnitedHealth’s cybersecurity practices and their failure to protect sensitive healthcare data. Lawmakers have called for stricter regulations and more stringent requirements for healthcare organizations to ensure that such breaches do not happen again. This incident has sparked a broader conversation about the need for improved cybersecurity standards across the healthcare industry.
The Change Healthcare data breach, confirmed on October 22, 2024, by UnitedHealth, has become one of the largest healthcare data breaches in U.S. history What to do?United Health Group has shared crucial guidance on steps you can take following their recent data breach incident.
1. Enroll in free credit monitoringThe financial impact of the Change Healthcare data breach has been substantial. The February attack resulted in losses of $872 million, which grew to $2.45 billion by the end of September 2024. These costs included accelerated payments and no-interest loans to affected healthcare providers, rebuilding Change Healthcare’s systems, and incident response efforts. The financial burden was not limited to UnitedHealth alone; many healthcare providers who relied on Change Healthcare’s services also faced significant financial strain.
In addition to the direct costs of responding to the breach, UnitedHealth also faced reputational damage. The breach has eroded trust in UnitedHealth’s ability to protect sensitive data, and this loss of trust could have long-term financial implications. Patients and healthcare providers may be hesitant to work with a company that has experienced such a significant security failure, potentially leading to a loss of business and revenue.
The financial impact also extended to affected individuals. Those whose personal and financial information was compromised faced the risk of identity theft and financial fraud. Many individuals had to take steps to protect themselves, such as freezing their credit, monitoring their financial accounts, and being vigilant for signs of identity theft. The cost of these protective measures, both in terms of time and money, added to the overall burden of the breach.
How many people were affected by the breach?Over 100 million individuals were affected by the Change Healthcare data breach. This makes it one of the largest data breaches of healthcare information in history. The number of affected individuals underscores the scale of the attack and the extensive reach of Change Healthcare’s operations across the United States.
The Change Healthcare data breach leaked health insurance details, medical records, billing and payment information What type of information was stolen?The stolen data included health insurance details, medical records, billing and payment information, Social Security numbers, and other personal identifiers. Not all individuals had the same types of information compromised, but the diversity of the stolen data means that the potential risks are varied and significant. The exposure of such a wide range of information makes this breach particularly concerning for both individuals and the healthcare sector as a whole.
Who was responsible for the Change Healthcare data breach?The ransomware attack was carried out by the ALPHV/BlackCat group, a Russian-speaking ransomware gang. After the initial ransom payment, an affiliate of the group formed a new ransomware operation called RansomHub, demanding additional payment from UnitedHealth. This series of events highlights the challenges of dealing with ransomware groups, as even paying the ransom does not guarantee the safety of the stolen data.
