The Dark 24301 Belgium Combolist Leak Exposed 20,945 Accounts

A Combolist Labeled "Dark 24301_Belgium" Surfaced on Telegram

On August 19, 2026, HEROIC analysts discovered a combolist file named "Dark 24301_Belgium" uploaded to a Telegram channel. The file contained 20,945 records, each pairing an email address with a plaintext password and a URL pointing to the site the credential was pulled from. The "Belgium" tag in the file's name suggests the uploader is marketing this batch as tied to Belgian accounts or services, though HEROIC has not independently verified the geographic makeup of every record.

Why This Is Dangerous

Nearly 21,000 email and password pairs stored in plaintext gives an attacker instant, ready-to-use access with no cracking or guessing required. Each record in this file links directly to the website it was meant for, meaning a criminal can open the list and start attempting logins immediately, and any password reused elsewhere puts those other accounts at risk too.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the associated sites or services

Why This Matters

A combolist of this size gives attackers a substantial pool of accounts to run through automated credential stuffing tools, testing each stolen login against banking sites, email providers, and popular online services. A single successful match can lead to account takeover, unauthorized financial transactions, or identity theft, particularly when the compromised account is an email inbox that can be used to reset passwords everywhere else.

How This Regional Combolist Was Built

Combolists like "Dark 24301_Belgium" are typically assembled by combining credentials pulled from a mix of older data breaches, phishing pages, and malware infections, then sorted and labeled by region or country to make the file easier for buyers to search and target. Telegram channels have become a common distribution point for lists like this because they can be shared instantly and reposted quickly if a channel is taken down.
