HQ MIX COMBO TEST NEO3690: Dark Web Intel Finds 10,050 Leak

Dark Web Intel Uncovers a 10,050-Record Stealer Log Tagged "HQ MIX COMBO TEST NEO3690"

On February 18, 2025, HEROIC analysts monitoring Telegram channels used for trading stolen data found a stealer log dataset labeled "HQ MIX COMBO TEST NEO3690." The file contained 10,050 records, and each one paired an email address with a plaintext password and the URL of the site that login was used on.

Why This Stealer Log Is Dangerous

At over 10,000 records, this dataset gives an attacker a large, ready-to-use list of working logins. Because the passwords sit in plaintext, there is no cracking step involved, anyone who obtains the file can read and use the credentials right away. Paired with the exact URL for each account, the data removes any guesswork about where a stolen password will actually work.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the site each login was used on

Why This Matters

A list this size is well suited to credential stuffing, where attackers run automated scripts that try each stolen email and password combination against other popular websites. Anyone among these 10,050 people who reuses passwords is at heightened risk of account takeover on services well beyond the one exposed here. The included URLs make each attempt more targeted, cutting down the trial and error an attacker would otherwise need.

How Stealer Logs Work

Stealer logs are produced by malware that infects a device and silently pulls saved passwords, autofill entries, and browsing data before sending it back to the attacker running the malware. Common infection routes include pirated software, fake installers, and malicious attachments. Large batches like this one, often labeled with test or combo tags, get traded and reshared on Telegram and dark web forums, the exact environment HEROIC's analysts monitor to catch leaks like this one early.

Check If You Are Affected

With over 10,000 records in this leak, the odds that your information is included are worth checking directly. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like this one, so you can see exactly what has been exposed and secure your accounts before someone else does.
