3.1K Telegram Stealer Log Exposes 2,609 Login Credentials

On 20-Apr-2026, a stealer log referred to as 3.1K was uploaded to a Telegram channel by an anonymous user. Despite the rounded nickname, HEROIC's verification found the file contains exactly 2,609 records, including email addresses, plaintext passwords, and the URLs of the sites those credentials belong to.

Why the Real Number Behind 3.1K Matters

Nicknames like "3.1K" are shorthand used by the people trading these files, and they are rarely exact. What matters is the precise count HEROIC confirmed: 2,609 working logins, each stored in plaintext, meaning anyone who downloads the file can use them immediately without cracking a single password.

What Was Exposed in the 3.1K Stealer Log

• Email addresses
• Plaintext passwords
• URLs of the websites and services those passwords unlock

Every one of the 2,609 entries pairs a working password with the exact site it opens, turning the file into a ready-to-use access list rather than raw, disconnected data.

Why This Matters for the 2,609 People Affected

Once a file like this circulates on Telegram, it is typically copied, resold, and run through automated tools within days. That creates a handful of concrete risks:

• Credential stuffing: attackers test each email and password combination against banking, shopping, and email platforms, betting on reused passwords.
• Account takeover: since the exact login URL is included, criminals can go straight to the correct site and sign in as the victim.
• Identity theft: a compromised email account often unlocks password resets on other services, exposing more personal information.
• Financial fraud: if any linked site touches payment details or banking access, stolen credentials can lead to direct financial loss.

How a Stealer Log Like 3.1K Gets Made

Files like this come from malware, often hidden inside cracked software, game cheats, or fake downloads, that installs itself quietly on a victim's device. Once active, it scans the browser for saved logins, capturing usernames, passwords, and the exact web addresses they were entered on. That data is sent back to whoever controls the malware, compiled into a single log, and shared or sold, in this case through a Telegram upload labeled 3.1K for its approximate size.

Check If You Are Affected

If you have saved a password in your browser or reused a login across multiple accounts, it is worth checking whether your information is part of this exposure or another one. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, and tells you instantly if your email appears.
