3.4M Records Leaked in 3.5KK Private MIX Ultra Telegram Breach

HEROIC analysts tracked a combolist known as "3.5KK Private MIX Ultra hit uploaded by a Telegram User" after it began circulating on April 2, 2023. The file contains 3,415,826 individual records, each pairing an email address with a plaintext password and a matching URL, the kind of ready-made list criminals use to break into accounts in bulk.

Why This Telegram Combolist Is Dangerous

Because the passwords in this file were stored and shared in plaintext, anyone who downloads it can read every credential instantly, no cracking or decryption required. Pair that with the included URLs, which point to the sites each login belongs to, and an attacker has a plug-and-play map for logging straight into real accounts.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to the accounts

Why This Matters

Combolists like this one are built for a single purpose: credential stuffing. Attackers feed the email-password-URL combinations into automated tools that test the same login on banking sites, email providers, and social media platforms. Anyone who reused a password across multiple accounts is exposed to account takeover, and from there, identity theft and financial fraud become very real possibilities.

How Combolists Work

A combolist is simply a compiled file of login credentials, gathered from older breaches, malware infections, or other leaks, and packaged into one text file for easy reuse. Unlike a raw database dump from a single company, a combolist can mix data from many different sources. Because the passwords here are already in plaintext, this list required no extra effort from whoever uploaded it to Telegram, it is ready to use the moment someone opens the file.

Check If You Are Affected

If you have ever reused a password across different sites, it is worth finding out whether your information turned up in this combolist or any of the other breaches HEROIC tracks. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs, combolists, and database dumps like this one, so you can see your exposure and change any at-risk passwords before someone else uses them first.
