The 4756_Japan_KRDCLOUD Combolist Leaked Days Ago: 4,556 Exposed

HEROIC analysts identified a combolist titled 4756_Japan_KRDCLOUD that a Telegram user uploaded on 30-Jul-2026, just days ago. The file contains 4,556 records pairing email addresses with plaintext passwords, along with the URLs of the sites those credentials unlock. | WHY THIS IS DANGEROUS: Because this data surfaced so recently, the credentials inside are likely still active. The passwords are stored in plaintext and matched to a specific URL, so an attacker can open the file and immediately try the exact email and password combination on the login page it belongs to. | WHAT WAS EXPOSED: Email addresses; plaintext passwords; URLs identifying which site each credential unlocks. | WHY THIS MATTERS: A freshly leaked combolist like this one is especially risky because the credentials have not had time to go stale. Attackers move quickly to run automated login attempts across banking sites, email providers, and social platforms, a tactic known as credential stuffing, before victims have a chance to change their passwords. | HOW COMBOLISTS WORK: A combolist is a compiled file of email or username and password pairs, often assembled from multiple smaller breaches or stolen-credential sources and repackaged for resale or free distribution on Telegram channels and dark web forums. Because it mixes data from several origins, a combolist can be harder to trace to one breach, but the credentials inside are frequently still active and usable. | CHECK IF YOU ARE AFFECTED: If you want to know whether your email appears in this combolist or any other leaked dataset, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records.
