Muji Says Full Credit Card Numbers May Have Leaked
Listen to the story
Ryohin Keikaku, the company behind the popular Muji brand, has given a new warning about a possible data breach.
A data breach happens when private information is stolen or shared without permission.
The company first reported that customer information may have leaked earlier. Now a new investigation has found a more serious problem.
According to the new findings, full credit card numbers for about 1.09 million people may have been leaked.
This is more serious than before, because full card numbers can be used for fraud, which means stealing money through tricks.
Ryohin Keikaku released an official notice to inform customers about this new discovery.
The company said it is still checking the situation and has not confirmed every detail yet.
A leak of full card numbers is especially dangerous because hackers or criminals could use them to make unauthorized purchases.
The term unauthorized means something done without permission or the right to do it.
This case shows how companies must protect customer data carefully, because even trusted brands can face security problems.
Ryohin Keikaku has not given full details about how the leak happened or who may be responsible.
Customers are advised to watch their card statements closely until the company shares more information.
The investigation is continuing, and more updates are expected in the future.
