Napoleon Corp Leak: 266 Stolen Passwords Hit the Dark Web

HEROIC analysts spotted a small but notable stealer log dump called Napoleon Corp, uploaded by a Telegram user on October 30, 2025. The file contains 266 records, each pairing an email address with a plaintext password and the URL of the account it opens. It is far smaller than the mega leaks that make headlines, but for the handful of people caught up in it, the danger is exactly the same.

Why the Napoleon Corp Leak: 266 Records Still Matters

Small dumps like this one often get overlooked, but attackers do not care about scale, they care about working credentials. With plaintext passwords sitting right next to the email and login URL, an attacker can log directly into every one of the 266 accounts without cracking a single hash. In some ways, a smaller file even gets more focused attention from criminals who prefer quality over quanity when testing stolen logins.

What Was Exposed in the Napoleon Corp Dump

• Email addresses belonging to real users
• Plaintext passwords with no encryption applied
• URLs identifying the exact site each credential unlocks

HEROIC confirmed 266 total records inside the file, all connected to users based in the United States.

Why This Matters Even at This Scale

Every one of these 266 records represents a real person whose login could be tested against other websites through credential stuffing. If the password was reused anywhere else, the attacker moves straight into account takeover, and from there identity theft and financial fraud become genuine risks. Size does not determine harm, exposure does, and these accounts are just as exposed as any that show up in a million record breach.

How a Stealer Log Like Napoleon Corp Gets Created

Infostealer malware is behind dumps of every size, including small ones like this. It infects a device through a fake download, a pirated program, or a phishing link, then quietly pulls saved passwords and account URLs straight out of the browser. The resulting file gets uploaded to Telegram channels or dark web forums under a name like Napoleon Corp, where it can be sold, traded, or tested by anyone with access to the channel.
