Search Your Email: Mix_Cleaned_Normalized Leaked 3.4M Records

HEROIC analysts identified a large combolist named mix_cleaned_normalized uploaded to a Telegram channel on February 18, 2026. The file contains 3,379,987 records pairing email addresses with plaintext passwords, along with URLs pointing to the login pages where each credential pair applies. The name reflects how the file was processed: raw stolen credentials from many sources compiled, deduplicated, and formatted into a single clean list.

Why the mix_cleaned_normalized Leak Is Dangerous

At nearly 3.4 million records, this is one of the largest combolists in this batch, and its plaintext passwords are ready to use the moment someone downloads the file. A dataset this size gives automated attack tools an enormous pool of credentials to test against websites and services across the internet.

What Was Exposed in This Combolist

• Email addresses
• Plaintext passwords
• URLs linked to each set of login credentials

Why This Matters for the 3,379,987 Accounts Involved

A combolist of this scale is built specifically for large-scale credential stuffing, where automated tools run millions of email and password combinations against banking sites, email providers, and shopping platforms in bulk. If your credentials are among these 3,379,987 records and you reused that password anywhere else, your other accounts are at immediate risk of takeover, financial fraud, or identity theft.

How Cleaned and Normalized Combolist Dumps Like This One Work

Raw stolen credentials from stealer logs, phishing pages, and older breaches often arrive in inconsistent formats and contain duplicates. A cleaned and normalized file like this one has been processed to remove duplicate entries and standardize the formatting, making it easier for buyers to load directly into credential stuffing tools. That processing step is what turns a messy pile of stolen data into a ready-to-use attack resource.
