Petdoc warns former Hairu staff data may have leaked in Douzone Bizon breach
Petdoc said resident registration and bank account numbers from before its April 2022 merger with Hairu may have been exposed.
Petdoc said on October 30, 2026 that personal information belonging to former Hairu employees and business partners may have been exposed as a result of a breach of Douzone Bizon's backup server, according to dailysecu.com.
The data that may have leaked includes resident registration numbers and bank account numbers. Petdoc said the affected records date from before its April 2022 merger with Hairu, when the former Hairu business — now the Popoz Gimpo branch — used Douzone Bizon's ERP system.
