This includes health insurance details, medical records, billing and payment information, along with personal data such as phone numbers, addresses, and in some instances, Social Security Numbers and government ID numbers.
Overview of the UnitedHealth Data Breach
Initial Breach Disclosure
In February 2024, UnitedHealth’s subsidiary Change Healthcare experienced a significant ransomware attack that caused substantial disruption across the U.S. healthcare system. UnitedHealth initially reported to the US Department of Health and Human Services Office for Civil Rights that 100 million individuals were affected by this cybersecurity incident.
Revised Impact Assessment
UnitedHealth later revised the impact of the Change Healthcare cyberattack, acknowledging that approximately 190 million people had their personal and healthcare data compromised. This updated figure was nearly double the number originally reported.
Nature of Stolen Data
The stolen data encompasses a wide range of sensitive information, including health insurance details, medical records, billing and payment data, as well as personal identifiers like phone numbers, addresses, Social Security Numbers, and government ID numbers.
Ransomware Attack Details
The attack was orchestrated by the BlackCat ransomware gang, also known as ALPHV. They gained access to Change Healthcare’s IT systems using stolen credentials and managed to exfiltrate 6 terabytes of data before encrypting the computers.
Disruption Caused by the Attack
Due to the ransomware attack, healthcare providers were hindered from submitting claims, and pharmacies could not process discount prescription cards. Consequently, patients were forced to pay the full cost for their medications.
Ransom Payment and Aftermath
Responding to the attack, the UnitedHealth Group confirmed it paid a ransom of $22 million to obtain a decryption key and prevent the release of the stolen data. However, the affiliate of BlackCat responsible for the attack claimed they were scammed by BlackCat, which subsequently executed an exit scam, taking the entire ransom for themselves.
Data Compromise and Additional Demands
Despite the ransom payment, the attacking party did not delete the stolen data as agreed upon. They partnered with RansomHub, a different ransomware operation, and began leaking the stolen data, effectively initiating an additional ransom demand.
Speculation on a Second Ransom Payment
The Change Healthcare entry on RansomHub’s data leak site vanished after a while, which led to speculation that UnitedHealth may have met the new ransom demand to prevent further data leakage.
Financial Implications for UnitedHealth
UnitedHealth reported significant financial losses due to the cyberattack. Initial losses were reported at $872 million, which escalated to an estimated $2.45 billion for the nine months leading up to September 30,
