Napoleon Corp Telegram Dump UP 413 Exposed 229,388 Accounts

On October 27, 2025, a file labeled UP 413 684KK Napoleon Corp appeared in a Telegram channel dedicated to sharing stolen credentials. Buried inside were 229,388 records of plaintext emails, passwords, and the web addresses tied to each one, all lifted straight from infected computers.

Why This Is Dangerous

Nothing about this data needs to be cracked or decoded before it can be used. Every password sits in the open, ready for an attacker to copy and paste into a login form. With 229,388 entries to work through, criminal groups don't even need to target individuals, they simply run the entire list through automated software and see what sticks. It's a numbers game, and the sheer size of this dump makes it a profitable one.

What Was Exposed

• Email addresses (229,388 records)
• Plaintext passwords with zero encryption
• URLs identifying exactly which sites each login belongs to

Why This Matters

Every one of those 229,388 accounts is now a potential target for credential stuffing, a technique wich lets attackers test stolen logins accross hundreds of websites automatically. If any of those passwords are still active, the account holder could loose access to email, social media, or financial accounts without warning. People who use the same password in multiple places are especially at risk, since one leaked login can cascade into several compromised accounts.

How Stealer Logs Work

Dumps like UP 413 684KK Napoleon Corp come from infostealer malware quietly installed on victims' machines, often through a phishing email or a fake software installer. Once running, the malware digs through saved browser passwords, autofill data, and active login sessions, then packages everything into a log file. That file eventually gets uploaded to Telegram, where it can be downloaded by anyone who finds the channel, no hacking skill required.
