2.76 mln pieces of customers' info at Hollys leaked in cyberattack

On October 19, the South Korean coffee chain Hollys announced that 2.76 million pieces of customer information had been leaked through a cyberattack on its memberships program. The stolen data included customers' dates of birth, phone numbers, addresses, and email addresses, according to a notice posted on Hollys' website. The company stated that the leaked information consisted of temporary data files from a past membership service overhaul, not from its active customer database.

Hollys is currently investigating the extent of the incident and apologizes for causing customer concern. The cybersecurity breach follows a series of data leaks at local financial firms earlier in the month, with approximately 100,000 cases of personal information reportedly stolen from 16 financial institutions. Hollys operates around 530 outlets nationwide and is part of KG Group, a conglomerate with interests in steelmaking, car manufacturing, and logistics services.
