29.6kImpact: Personal information of all 29,553 members
In September 2026, the personal information of all 29,553 members of V-Class, the Seoul Volunteer Center’s online education platform, was leaked. The attacker exploited a vulnerability in the service provider’s system to install a web shell and steal database access privileges, and also sent spam text messages using the operator’s sender number. The operator became aware of the incident following notification from its text messaging service provider approximately 67 hours after the initial intrusion. The Seoul Metropolitan Government and the Seoul Volunteer Center activated a joint response framework and strengthened personal information security measures.
