A Telegram User Just Leaked 45,493 ‘CartelJohnDoe’ Records

On July 13, 2026, researchers tracking Telegram channels used for trading stolen data spotted a new stealer log labeled "CartelJohnDoe." Whoever uploaded it made no attempt to hide the scale: 45,493 records, each containing an email address, a plaintext password, and the URL of the account it belongs to.

Why This One Stands Out

At over 45,000 records, this is a larger haul than most single stealer log uploads on Telegram. The size alone makes it more likely that your information, or that of someone you know, is sitting inside it. And because the passwords were captured in plaintext, anyone who downloads the file can read them instantly, no cracking required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the matching login pages

Why This Matters

With 45,493 ready-to-use logins in circulation, automated credential stuffing attacks against banks, email providers, and retailers become far more likely. Anyone whose password was reused across multiple accounts is exposed to account takeover, identity theft, and financial fraud the moment this file changes hands.

How a Log This Size Gets Built

Large stealer logs like "CartelJohnDoe" are typically assembled from infostealer malware infections across many victims at once, often spread through pirated software, cracked games, or malicious ads. The malware silently copies stored browser passwords, autofill data, and session cookies from each infected machine, and the operator merges the results into a single file before naming and distributing it on Telegram or dark web forums.
