If You Use KRDCLOUD, This 2,828-Record Password Leak Affects You

In July 2026, HEROIC analysts found a combolist labeled "2869_Japan_KRDCLOUD" uploaded to a Telegram channel. Dated July 17, 2026, the file exposes 2,828 records, each containing an email address, a plaintext password, and an associated URL tied to accounts on the Japan-linked cloud service KRDCLOUD. Why This Leak Should Worry KRDCLOUD Users If you have an account with KRDCLOUD, or use the same password for it that you use elsewhere, this leak is worth your attention. The passwords in this file are stored in plaintext, meaning anyone who gets hold of the list can read your credentials directly and start testing them against your other accounts immediately. What Was Exposed in the KRDCLOUD Combolist Email addresses Plaintext passwords Associated URLs Why This Matters Credential lists like this one are built for credential stuffing, where attackers automatically try each email and password pair against dozens of other services. If you reused your KRDCLOUD password anywhere else, from email to online banking, a working match here could hand an attacker access to those accounts too, opening the door to account takeover, identity theft, and financial fraud. How Combolists Like This One Get Made A combolist is a compiled file of usernames or emails paired with passwords, often gathered from smaller breaches, phishing campaigns, or malware that steals saved login data directly from infected devices. Once a set of working credentials is confirmed, it gets bundled into a file like this 2,828-record list and shared or sold through Telegram channels, where it can be picked up and reused by anyone looking for accounts to break into. Check If You Are Affected If you use KRDCLOUD or reuse passwords across your online accounts, take a moment to check whether your information is part of this leak. HEROIC's free breach scanner searches more than 400 billion exposed records, so you can find out quickly and change any passwords that may have been compromised.
