Napoleon Corp Data Leak Exposed 178,617 Login Records Online

One day after a smaller Napoleon Corp related file appeared on Telegram, a second and much larger one surfaced on November 22, 2025. This version contained 178,617 records of stolen login data, more than 36 times the size of its predecessor, and it's a reminder that a single source of infected devices can keep producing new stealer logs over time.

Why This Is Dangerous

A leak of this size means a lot more people are potentially exposed at once. Each record ties an email address to a plaintext password and the exact URL it was used on, so an attacker doesn't need any technical skill to start using the data, wich means they can literally copy and paste a login into a website and see what happens. With 178,617 records to work through, even a low success rate still means thousands of accounts could be compromised.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs linked to each stolen login
• 178,617 total records exposed

Why This Matters

Large stealer log files like this one are often used to run automated login attempts across popular websites, a tactic known as credential stuffing. Attackers don't have to target Napoleon Corp specifically, they simply try each leaked email and password pair on banking sites, email services, and online stores, hoping that people reused the same password in more than one place, since many people still recieve no alert when this happens. Unfortunatly, that habit is incredibly common, which is exactly what makes large scale leaks so profitable for criminals.

How Stealer Logs Work

Stealer log malware spreads through infected downloads, cracked software, and phishing links, then quietly sits on a device recording every password entered into a browser or saved credential manager. As more devices get infected, the operator collects larger and larger batches of stolen data, occasionally releasing them in stages, which would explain why a second, bigger Napoleon Corp file appeared just a day after the first. The data is organized by website, making it simple for buyers to search for specific targets like banks or email providers.
