26,586 Records Leaked From Napoleon Corp Stealer Log Dump

26,586. That is the exact number of records sitting inside a file labeled "UP 417 98K Napoleon Corp," uploaded to a Telegram channel on 28-Oct-2025. The odd, code-like name is typical of how these files circulate in dark web spaces, stripped of context but full of real people's login information.

Why This Is Dangerous

A batch this large means an attacker has plenty of raw material to work with, whether that means testing logins for account takeover, building phishing lists, or reselling smaller slices of the file to other buyers. The plaintext passwords included mean there is no technical barrier stopping someone from using the credentials the moment they get their hands on the file.

What Was Exposed

• 26,586 total records
• Email Addresses
• Plaintext Passwords
• URLs connected to the accounts

Why This Matters

When tens of thousands of email and password combinations circulate freely, the effects reach far beyond the original victims. Attackers often run these lists against completely unrelated services in a technique called credential stuffing, hoping people reused the same password elsewhere. Its a numbers game for them, and a leak of this size gives them plenty of chances to succeed.

How Stealer Logs Work

Stealer malware spreads through malicious downloads, cracked software, and phishing emails, then quietly extracts saved passwords and cookies from an infected browser without the user noticing anything unusual. The stolen data gets compiled into log files like this one, sometimes labeled with cryptic codes referencing the malware operator or campaign, before being shared or sold in bulk.

Check If You Are Affected

With over 26,000 records involved, its worth taking a moment to check your own accounts. HEROIC's free breach scanner searches more than 400 billion leaked records, so you can find out seperately whether your email or password shows up in this leak or any other before it gets used against you.
