Prabang Data Breach Exposes Personal Data of Seven Members in Third Hack Within a Month
South Korean virtual asset exchange Prabang has disclosed that a security breach exposed the personal data of seven of its members, according to the company's official announcement published on Thursday, November 5, 2026.
Unauthorized External Access in October
The intrusion stems from access by an unauthorized external party around October, per the announcement. Further details about the precise timing of the access, the specific categories of data involved, and any remedial measures were not included in the available disclosure.
The report identifies the incident as the third hack targeting the exchange within roughly a month. The missing specifics — precise timing, affected data categories, and remedial measures — are the points to track in any follow-up communication from the company.
Regulatory Context
Organizations handling personal information in South Korea fall under the Personal Information Protection Act (PIPA), which obliges companies to notify affected individuals and report breaches to the relevant authorities, including the Personal Information Protection Commission. In this incident, that framework translates into notification duties toward the seven members whose data was exposed. Virtual asset service providers in the country must additionally maintain Information Security Management System (ISMS-P) certification as a condition of operation under the Financial Services Commission's regulatory framework.
The South Korean cryptocurrency sector has historically been a recurring target for cyberattacks, with breaches affecting exchanges such as Bithumb and Upbit in previous years.
