1.5M MIx Good For All Targets: US Leak Exposes Emails, Passwords

1.3 Million Records From a Telegram Stealer Log Surface in HEROIC's Dark Web Monitoring

On February 13, 2025, HEROIC analysts logged a stealer log dataset shared by a user on Telegram under the label "1.5M MIx Good For All Targets." The file contained 1,345,874 records, each pairing an email address with a plaintext password and the URL of the site the login was used on. Stealer logs like this one are a direct byproduct of malware infections, and this batch appears to target a broad mix of accounts rather than one specific service.

Why This Stealer Log Is Dangerous

What makes this leak especially risky is that the passwords were stored and shared in plaintext, meaning anyone who gets their hands on the file can read them immediately, no cracking or decryption required. Combined with the email address and the exact URL where that password was used, an attacker has everything needed to log straight into the account it belongs to. There is no guesswork involved: the data points directly to a specific login on a specific site.

What Was Exposed

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

Why This Matters

Because the passwords are readable as-is, this data is ready to use for credential stuffing, where automated tools try the same email-and-password pair across dozens of other websites. If you have ever reused a password, one exposed login can turn into several compromised accounts. The paired URLs also make account takeover faster, since an attacker knows exactly which site to target instead of guessing where else you might have an account.

How Stealer Logs Work

A stealer log is the output of malware that infects a device and quietly copies saved passwords, browser autofill data, and login sessions before sending everything back to whoever controls the malware. The infection can happen through a pirated download, a malicious attachment, or a fake software installer. Once the stolen data is collected, it is often bundled into a file like this one and sold or shared in dark web communities and Telegram channels, exactly where HEROIC's analysts found this dataset.

Check If You Are Affected

If you think your email might be part of this or any other leak, you can find out in seconds. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, including stealer logs like this one, and shows you exactly what has been exposed so you can change passwords before someone else uses them.
