Luxury brand Louis Vuitton said data breaches at its stores in Turkey, South Korea and the United Kingdom exposed the sensitive information of some customers.

Last week, Turkey’s Personal Data Protection Board released a notice to the public about the data breach, writing that an investigation into the incident is ongoing.

According to Turkish officials, the data breach began on June 7 and was discovered on July 2. Hackers breached the service account of a third party service provider to access a database containing customers' personal data. 

While the notice does not say what data was breached, Turkish officials said it affected 142,995 people living in the country who were Louis Vuitton customers. Louis Vuitton submitted a notice to the Personal Data Protection Board, prompting the response. 

The announcement comes about one week after Louis Vuitton warned customers in South Korea of another data breach. Last week, the company’s U.K. branch also announced a data breach.

While it is unclear whether the incidents are connected, the company’s South Korea arm confirmed that its incident occurred around the same dates as the Turkey breach.  

A statement from Louis Vuitton South Korea said the breach involved names, contact information and other data provided by customers. No financial information was included in the breach, which was first reported by Bloomberg.

The company said it is conducting an internal investigation and urged customers to be suspicious of unexpected communication. 

Louis Vuitton is one of several companies under the banner of French conglomerate LVMH, and is far from the only luxury brand to deal with a cyberattack in recent months. 

Both Dior and Tiffany announced data breaches or security incidents that exposed customer and employee data as law enforcement in the U.S. and Europe warned of a larger campaign by the hacking group Scattered Spider targeting retail companies. 

Several retail companies like Victoria’s Secret, North Face, Adidas and others dealt with breaches caused by cyberattacks.
