HEROIC Researchers Find 1.25M Passwords in SUHQ MIX Base Leak

HEROIC Researchers Find a 1.25 Million-Record Stealer Log on Telegram

HEROIC's dark web research team identified a stealer log named "1.6KK SUHQ MIX Base," uploaded to a Telegram channel on 02-Apr-2023. Researchers counted 1,253,517 individual records in the file, each pairing an email address with a plaintext password and the URL of the site the credentials were captured from.

Why the SUHQ MIX Base Stealer Log Is Dangerous

Researchers note that this file is dangerous because it hands an attacker a working login with no extra effort required. Each record already links a specific email and password to the exact website it unlocks, removing any need to guess or crack anything. Because the passwords were captured and stored in plaintext, anyone who obtains the file can read them the moment they open it.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the websites where the credentials were used

Why This Matters

With more than 1.25 million working email and password combinations in one file, researchers flag this as prime material for account takeover, since each record lets an attacker log directly into a specific account. It also fuels credential stuffing: anyone who reused that same password elsewhere faces risk on those accounts too, even ones with no connection to this particular file.

How Stealer Logs Work

Researchers explain that stealer logs are produced by malware that infects a device, quietly reads through the browser's saved passwords and active sessions, and sends everything back to whoever controls the malware. The result is a plain text file listing exactly which login works on which website. Files of this size, like "1.6KK SUHQ MIX Base," are then packaged and traded on Telegram, which is exactly where HEROIC's team found it.

Check If You Are Affected

With over 1.25 million records in this file, there's a real chance your information is included. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you right away if you've been exposed. If you get a match, change that password immediately and avoid reusing it anywhere else.
