Mix Combo Leak: 4,987 Email and Password Pairs Exposed

Nearly 5,000 Logins Exposed in a Mixed Combo List

HEROIC analysts identified a file titled "MIX COMBO" uploaded to Telegram on June 7, 2026. The list contains 4,987 records that pair email addresses from various providers with plaintext passwords and the URLs those credentials unlock.

Why This Is Dangerous

Because the passwords are stored in plaintext and each one is matched to a specific URL, an attacker can immediately see which site a login belongs to and try it without any extra work. A "mix" list spans many different services, which multiplies the number of accounts a single leaked password could unlock if it was reused.

What Was Exposed

• Email addresses (mixed providers)
• Plaintext passwords
• Associated login URLs

Why This Matters

Nearly 5,000 working logins is more than enough to fuel automated credential stuffing attempts, where attackers test each pair against many other websites at once. If any of these passwords were reused, the result can be account takeover on completely unrelated services, from email and social media to online shopping accounts.

How Mixed Combo Lists Come Together

Mixed combo lists are usually built by combining several information-stealer malware logs or older breached databases into one file, then sorting by whatever the seller thinks buyers want, in this case a broad "mix" rather than a single service. This makes the list versatile for attackers looking to cast a wide net.

Check If You Are Affected

With almost 5,000 accounts involved, it is worth checking your own email against this leak. HEROIC's free breach scanner searches more than 400 billion leaked records, including combo lists like this one, so you can quickly confirm your exposure and change any affected passwords.
