Personal information of 220,000 users has been leaked from Gangnam Unni, South Korea's largest medical aesthetic information platform.

User A, who has used the medical aesthetic platform Gangnam Unni for over five years, felt a wave of anxiety upon hearing the news of the personal data leak, having frequently posted procedure reviews.

[User A / Victim of Gangnam Unni Personal Data Leak: It is a bit embarrassing to talk about what procedures I've had done, but that kind of information could be exposed. Aside from news about platforms like TVING getting hacked, this site contains different types of information, so those aspects are quite worrying.]

Healing Paper, the operator of Gangnam Unni, announced that an abnormal access attempt occurred on the 4th through a system pathway used to view Gangnam Unni consultation records, resulting in the leakage of customer personal information.

The company explained that after detecting abnormal signs, it blocked the access route, but later confirmed that the same attacker attempted access through another route the following day.

The number of leaked accounts confirmed so far is approximately 220,000.

South Korean users account for the largest share at 160,000, along with a significant number of users from Japan, Thailand, and China.

The problem is that the leaked information is extremely personal and sensitive.

It includes names, phone numbers, and email addresses, as well as consultation procedure names, hospital and doctor names, actual procedure histories, payment amounts and methods, and even consultation photos.

Gangnam Unni stated that it has notified users of the leak and requested a police investigation after securing circumstances that could identify the attacker.

[Kwak Jin / Professor of Cybersecurity at Ajou University: Precise forms of targeted attacks can occur. When details such as procedures received or specific body areas are included, it can create a situation where victims are much more vulnerable to falling for scams.]

Experts advise that if users are using the same ID and password on other services as the ones used for Gangnam Unni, changing them promptly is currently the best way to prevent additional damage.
