Personal Information of Students and Parents Leaked in Hacker Breach at Saenggakhan Hwangso Math Academy in Daechi-dong

A personal information leak has occurred at Saenggakhan Hwangso, a math academy that operates more than 80 branches nationwide, including the Daechi branch in Gangnam-gu, Seoul.

On September 18, Saenggakhan Hwangso announced on its website that it had confirmed a hacker intrusion into its test reservation site on September 17.

The academy explained, "Given that the attackers claimed to have secured all data, there is a high likelihood that the personal information of parents and students who have made test reservations through this site has been leaked."

The leaked personal information includes students' names, schools, grades, dates of birth, and parents' phone numbers.

After the incident, Saenggakhan Hwangso temporarily closed the affected website and reported the personal information leak to the relevant authorities. The academy is notifying parents whose information was leaked via text message and is preparing materials to request a police investigation.

Saenggakhan Hwangso also advised, "If you receive any contact or messages from unknown individuals, please be aware that it could be a voice phishing attempt and respond calmly. Do not provide your personal information or click any links."

The website is scheduled to resume operation after completing measures to prevent a recurrence.

The Personal Information Protection Commission received a report around 9 p.m. the previous day and is currently investigating the circumstances of the incident, including the number of victims. A representative from the Commission explained, "The items reported leaked by the academy are basic personal information such as names, contact information, and email addresses. Sensitive data such as academic transcripts or payment information were not involved."
