The 16.7K Mix Combolist Dump: 15,453 Valid Logins Exposed

On 6 August 2026, a combolist titled "16.7K Mix Combo list Full Valid" surfaced on Telegram. HEROIC verified the file contains 15,453 records of email addresses, plaintext passwords, and associated URLs, labeled by the uploader as "full valid," meaning the credentials were tested and confirmed to work.

Why This Is Dangerous

A "mix" combolist pulls credentials from a variety of sources rather than one single site, which means the 15,453 accounts in this file could belong to email providers, streaming services, shopping sites, or anything else. Because the passwords are plaintext and marked valid, an attacker can use them immediately with no extra effort.

What Was Exposed

The "16.7K Mix Combo list Full Valid" file contains:

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Because this list mixes credentials from many different services, it's especially useful for credential stuffing, testing one stolen password across dozens of unrelated sites at once. Anyone in this file is at risk of account takeover, and if attackers gain access to an email account specifically, that access can cascade into banking fraud and identity theft.

How This Combolist Was Built

A "mix" combolist is typically assembled by merging credentials scraped from several older breaches, phishing campaigns, or stealer malware logs, then running them through a validity checker before distribution. The "full valid" tag is meant to reassure buyers that the list has already been quality-checked, making it more attractive on Telegram marketplaces.

Check If You Are Affected

Since this combolist blends credentials from multiple sources, it's worth checking regardless of which accounts you use. HEROIC's free breach scanner searches more than 400 billion leaked records to tell you if your email is part of this exposure.
