235 GB of PHI and internal documents dumped; Chaos claims it comes from Healthcare Highways
A ransomware group called Chaos claims to have published 235 gigabytes of protected health information and internal documents allegedly taken from Healthcare Highways, a medical provider network company. The data was posted to a dedicated leak site after an apparent deadline passed.
Why this matters: Healthcare Highways sits between employers, insurers, and hospital networks, which means the data it holds is not just patient names. It can include claims history, diagnoses, and benefits details tied to people's jobs. When that kind of information leaks, the people affected rarely find out quickly and almost never have a say in what happens next. Ransomware groups have learned that healthcare data is worth dumping publicly because the pressure it creates is enormous. The real cost lands on patients, not executives.
