WEVERSE , the fan platform operated by HYBE-affiliated Weverse Company, has disclosed a security incident that affected 422,584 user accounts. The organisation says the data exposed mainly consisted of internal identifiers that cannot be used outside Weverse’s systems, and are not users’ names, phone numbers, or other contact details capable of directly identifying individuals.
The incident came to light after Weverse received a notification from the Korea Internet & Security Agency (KISA) on 3 September that an external source reported a vulnerability. Weverse stated that it launched an internal investigation and took emergency response measures. Weverse Company President Yang Zooil emphasised that the exposed identifiers are confined to internal use and cannot be exploited outside the platform.
