The 6389_Canada_KRDCLOUD Leak Means 6,300 Passwords Are Exposed

HEROIC Analysts Uncover the 6389_Canada_KRDCLOUD Combolist

In July 2026, HEROIC threat analysts identified a combolist file uploaded by a Telegram user under the label 6389_Canada_KRDCLOUD. The file exposed 6,300 records containing email addresses, plaintext passwords, and the URLs each credential was tied to, adding another batch of live login pairs to the pool that cybercriminals draw from when targeting new victims.

Why This Leak Puts Real Accounts at Risk

Because the passwords in this file are stored in plaintext, anyone who downloads it can read the exact password next to the exact email address with no extra work. Combined with the URL showing where each login was used, an attacker has a ready-made list of targets to try logging into directly. Anyone who reused one of these passwords on another account faces risk that extends well past the original site.

What Was Exposed in the 6389_Canada_KRDCLOUD Dump

• Email addresses
• Plaintext passwords
• URLs linking each credential to the site it was used on

Why This Matters for the 6,300 People in This File

Lists like this one fuel credential stuffing, where attackers run stolen email and password pairs against banking portals, email providers, and social platforms in bulk. Password reuse is what turns a single leaked combolist into a chain reaction of account takeovers, identity theft, and financial fraud across accounts the victim never expected were connected.

How a Combolist Like This One Gets Assembled

A combolist is a file that bundles together username or email and password pairs, often pulled from earlier breaches, stealer malware infections, or manual scraping, then formatted for easy reuse. Telegram channels have become a go-to place for uploading and trading these files because they let distributors reach buyers quickly with little accountability. Once a combolist like 6389_Canada_KRDCLOUD is posted, it tends to get copied and folded into larger collections, extending its reach far beyond the original 6,300 records.
