Louis Vuitton Korea suffered a cyberattack that compromised some customer data, the second time in recent months that hackers have targeted the world’s largest luxury group.

The Korean unit of LVMH’s flagship brand said an “unauthorized third party” accessed its systems on June 8 and some customer information was leaked. No financial data including credit card or bank account details were taken and the security breach has been contained, it said in a statement.

Louis Vuitton Korea said it is investigating the cyberattack and has notified relevant authorities. “We are strengthening the security of our systems and working with the best experts in cybersecurity,” it said.

Christian Dior Couture, LVMH’s second-largest fashion label, said in May it had been targeted by hackers who accessed some customer data. Le Monde newspaper reported the cyberattack took place in January.
