The 1.3K Russian Combolist Exposed 1,347 Accounts on Telegram

The 1.3K Russian Combolist Exposed 1,347 Accounts on Telegram

In May 2026, HEROIC threat analysts identified a combolist file uploaded by a Telegram user under the label 1.3K Russian. The file exposed 1,347 records containing email addresses, plaintext passwords, and the URLs each login was tied to, grouped together under a regional label that points to the accounts inside as Russian in origin.

Why This Combolist Is Dangerous

Because the passwords in this file are stored in plaintext, anyone who obtains it can read the exact password next to the exact email address without any cracking involved. Combined with the URL showing which site each login was used on, an attacker has a direct path to attempt access right away. If any of these 1,347 people reused a password elsewhere, the exposure reaches beyond the original account.

What Was Exposed in the 1.3K Russian Combolist

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

Why This Matters for the People in This File

Regionally grouped combolists like this one are often bought and sold by attackers looking to target a specific population, then used for credential stuffing against banking sites, email providers, and social platforms. Because password reuse is so common, a leak of 1,347 credentials can still lead to account takeover, identity theft, or financial fraud for the individuals whose data is included.

How a Combolist Like 1.3K Russian Gets Assembled

A combolist is a compiled file of username or email and password pairs, typically gathered from earlier breaches, stealer malware infections, or manual collection, then sorted and labeled by region or theme for easier resale. Telegram channels are a common place to trade files like this because they let sellers reach interested buyers quickly with little accountability. Once posted, a combolist tends to be copied and folded into larger collections, extending its reach past the original 1,347 records.
