2976_Russia_KRDCLOUD Leak: 2,948 Russian Accounts Exposed

HEROIC analysts identified a combolist file labeled "2976_Russia_KRDCLOUD" circulated on Telegram in August 2026, containing 2,948 records tied to Russian accounts. Each record pairs an email address with a plaintext password, and many entries also list the URL of the site the login was originally used on.

Why This Is Dangerous

Grouping accounts by country makes a combolist more useful to attackers who focus their efforts on a specific region, since they can target services and banks common to that country without wasting time on logins that will not apply. Because the passwords here are stored in plaintext and each is paired with a URL, an attacker can move straight to a working login the moment they open the file.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the original accounts

Why This Matters

When a leak is organized by country, attackers can more efficiently run credential stuffing against the specific banks, email providers, and shopping sites people in that region actually use. A password reused across a couple of accounts is all it takes for a single leaked credential to lead to account takeover, identity theft, or financial fraud.

How a Combolist Leak Works

A combolist like this one is built from login pairs, usually formatted as email:password, gathered from smaller breaches and then sorted, in this case by country, before being labeled and posted to a channel like this. That sorting step is what turns a generic pile of credentials into a targeted tool, since it tells a buyer exactly which region's accounts they are working with.

Check If You Are Affected

If you want to know whether your information appears in a regionally targeted leak like this one, HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this, so you can find out quickly and secure your account.
