7761_Japan_KRDCLOUD Leak: 7,369 Passwords Exposed Online

7761_Japan_KRDCLOUD: 7,369 Records Exposed in a Stealer Log

HEROIC analysts identified a stealer log named "7761_Japan_KRDCLOUD" on Telegram in July 2026, containing 7,369 records built from email addresses, plaintext passwords, and the login URLs tied to each account. Like other KRDCLOUD-branded logs, the file bundles credentials by batch and region, in this case labeled Japan.

Why This Is Dangerous

These 7,369 passwords are stored in plaintext, meaning anyone with the file can log directly into the associated accounts without needing to crack a single password. A log of this size is large enough to make automated testing against other websites worthwhile for an attacker.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs (the exact pages the credentials unlock)

Why This Matters

A leak in the thousands of records is more than enough for credential stuffing to succeed against at least some accounts, especially where passwords have been reused across email, banking, or shopping sites. Once an attacker gets into one account, they often pivot to others linked through the same email address.

How KRDCLOUD Logs Like This One Are Organized

KRDCLOUD is a distribution brand used by sellers of stolen credentials to package logs harvested by infostealer malware from infected devices. Batches are frequently labeled by region and a running count, which is why this file appears as "7761_Japan," distinguishing it from other regional batches sold or shared under the same KRDCLOUD name.

Check If You Are Affected

Regional batches like this one are easy to miss if you are not actively monitoring for them. HEROIC's free breach scanner checks your email against more than 400 billion breached and leaked records, so you can confirm your exposure and protect any account before it is used against you.
