Dark Web Intel: Japanese House Leaked 268,860 Food Delivery Records

HEROIC analysts identified the Japanese House (Японский Домик) breach in early 2022, uncovering 268,860 exposed customer records from this Russian sushi and food delivery service based in Berdsk. The breach occured through a database export, leaking the personal information of hundreds of thousands of local delivery customers across the Novosibirsk Oblast region of the Russian Federation.

What Attackers Can Do With Names and Phone Numbers From Japanese House

Even without passwords or financial data, a dataset of 268,860 names and phone numbers is a powerful tool for fraud. Attackers can launch SMS phishing campaigns impersonating the delivery service, make fraudulent calls posing as support agents, or sell the data to spam networks. The seperate combination of full name and direct phone number makes social engineering attacks highly convincing and accessable to low-skill threat actors.

Why Regional Food Delivery Breaches Carry Real Risk

Local delivery platforms collect accurate, up-to-date contact information because customers provide it to recieved their orders. This makes the data highly reliable for phishing, identity theft, and account takeover attempts on other services. With 268,860 records exposed, the Japanese House breach gives attackers a ready-made list of verified local contacts for targeted fraud campaigns.

How a Database Breach Works

A database breach occurs when an attacker gains unauthorized access to a platform's backend data storage, typically by exploiting security vulnerabilities such as SQL injection or misconfigured server permissions. The attacker then exports the database contents in bulk. In the Japanese House case, the breach resulted in a complete dump of customer records, including names and phone numbers used for delivery coordination.
