Change Healthcare

The Change Healthcare data breach in February 2024 significantly impacted over 100 million individuals, marking the largest-ever healthcare data breach in the US. An extensive cyber attack disrupted IT operations, affecting numerous applications, pharmacies, and healthcare providers. Sensitive personal and medical information such as names, Social Security numbers, and treatment details were compromised. The incident led to substantial costs, with UnitedHealth Group reporting $1.1 billion in related expenses. Despite ransom payments, issues with the hacker group BlackCat/ALPHV and subsequent attempts by RansomHub to extort the company exacerbated the situation.
