Personal Data of Approximately 220,000 Domestic and International Gangnam Unni Users Leaked

DataBreaches.net · · International · Data Breaches

Healing Paper, the company behind Gangnam Unni, a beauty and medical consultation platform, disclosed that unauthorized access to an API exposed personal data belonging to roughly 220,000 users in South Korea and internationally. The breach was detected on September 4 and publicly announced three days later.

Why this matters: A beauty and medical platform holds a specific kind of sensitive data. People using it share information about their bodies, procedures they are considering, and consultations with clinicians. That is not the same as a leaked email list. When that data walks out, it can follow people in ways they did not agree to. The breach involved an API that controlled access to consultation records, which means the exposure was not incidental. Someone reached directly into the records. Users deserve a clear account of exactly what was taken and who might have it now.
