Not Massive, But Real: MIX COMBO 3 Leaks 3,371 Passwords

MIX COMBO 3 Combolist Leak: 3,371 Records Exposed

In June 2026, HEROIC analysts identified a combolist labeled "MIX COMBO 3" uploaded to a Telegram channel. The file contained 3,371 records pairing email addresses with plaintext passwords and the URLs those credentials belong to.

Why This Is Dangerous

Because the passwords in MIX COMBO 3 are stored in plaintext, anyone who downloads the file can immediately start testing the 3,371 email and password pairs against real accounts, no cracking tools needed. The included URLs point attackers straight to the correct login page for each credential, removing the guesswork that normally slows an attack down.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

A combolist of 3,371 records is a solid working list for credential stuffing, even if it is smaller than some of the larger dumps circulating on Telegram. Attackers can run this entire file through automated tools in minutes, testing each pair against banking, email, and shopping accounts. Anyone whose password was reused elsewhere faces a real risk of account takeover, financial fraud, or identity theft.

How a Combolist Leak Works

A combolist mixes credentials from a variety of sources, typically older breaches or malware infections, and combines them into a single reusable file, hence the name MIX COMBO 3. The number in the name suggests it is part of an ongoing series from the same uploader, who likely shares similar files on Telegram on a recurring basis. Once shared, a file like this can be downloaded and reused by anyone who finds it.

Check If You Are Affected

With 3,371 records in this combolist, there is a real chance your email address is among them. HEROIC's free breach scanner checks your email against more than 400 billion leaked records to tell you instantly whether you have been exposed. If you find a match, change that password everywhere you have reused it and turn on multi-factor authentication for extra protection.
