Ramen Kuroda Leak Pairs Full Names With Birthdays for 25,831 Customers

HEROIC analysts identified a data breach at Ramen Kuroda, a Japanese restaurant chain operating in the Philippines, discovered on May 25, 2024. A database tied to the company's customer records was exposed and later appeared on an underground forum, affecting 25,831 people. The exposed data included email addresses, phone numbers, first and last names, birthdays, and gender.

Why the Ramen Kuroda Leak Is Dangerous

No passwords were included in this breach, so there is no direct risk of someone logging into an account with stolen credentials. The danger here is different: a full name paired with a birthday, phone number, and gender gives an attacker enough personal detail to impersonate a customer, answer security questions, or craft a convincing phishing message that references real, specific information. That combination of details is exactly what identity thieves look for when building a profile on someone.

What Was Exposed in the Ramen Kuroda Breach

• Email addresses
• Phone numbers
• First and last names
• Birthdays
• Gender

Why This Matters Even Without Passwords

People often assume a breach without passwords is low risk, but personal details like a birthday and phone number are frequently used to verify identity with banks, phone carriers, and customer support lines. Attackers can use this data for targeted phishing texts or calls that reference a customer by name and correct birth date, making the scam far more convincing, or attempt SIM swap fraud using the phone number and personal details together.

How a Database Breach Like This Happens

This breach appears to have come from a customer database used for loyalty programs or point-of-sale systems, the kind of system restaurants and retail chains rely on to track repeat customers. When these systems are not properly secured, an attacker who finds a vulnerability can export the entire customer table in one action. Restaurants and retail businesses are increasingly targeted this way because they hold large amounts of personal data but often invest less in security than banks or tech companies.

Check If You Are Affected

If you have ever ordered from Ramen Kuroda or signed up for its loyalty program, it is worth checking whether your details were part of this leak. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, so you can quickly find out if your name, phone number, or email address has been exposed anywhere.
