Napoleon Corp Breach: 148,026 Records Still Exposed 4 Months Later

Back on 20-Feb-2026, a user on Telegram quietly dropped a stealer log tied to Napoleon Corp, and it has been sitting out there ever since. The file contains 148,026 records pulled straight from infected devices, and more than four months later those credentials are still being passed around and definately still usable by anyone who finds them.

Why This Is Dangerous

The scary part about a leak like this isn't just the initial exposure, it's how long the data keeps circulating. Stealer logs like this one get copied, resold, and mixed into other combolists, so even months after the original post the same emails and passwords keep showing up in new places. If you haven't changed a password since February, there is a real chance your login is still floating around out there.

What Was Exposed

• 148,026 total records
• Email Addresses
• Plaintext Password
• URLs

Why This Matters

Because the passwords in this log were stored in plaintext, whoever grabs the file doesn't need to crack anything, they can just recieve the data and start logging in. Combined with matching URLs, an attacker can automate login attempts across the exact sites tied to each account, which makes credential stuffing attacks much faster and far more effective.

How Stealer Logs Work

A stealer log is generated by malware that infects a person's computer, usually through a cracked download, fake software update, or a malicious attachment. Once it occured, or rather once the infection took hold, the malware quietly scrapes saved browser passwords, autofill data, and cookies, then bundles everything into a text file the attacker can sell or share for free on Telegram.

Check If You Are Affected

You do not have to guess whether your information showed up in this leak or any other one. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including logs just like this Napoleon Corp file, so you can find out in seconds and start locking down any account that needs a new password.
