1. Japanese retailer Muji's user data, including names, addresses, and phone numbers, might have been leaked due to a cyberattack on e-commerce and logistics platform Askul.
2. Ryohin Keikaku, the operator of Muji outlets, is investigating the extent of the data breach but assures credit card information was unlikely to be compromised.
3. Other retailers such as Sogo & Seibu and Loft also outsourced logistics operations to Askul's subsidiary, but no breach has been found for them so far. Askul is cooperating with outside organizations to check for further information theft and strengthening its monitoring system.
