UP 418 288K Napoleon Corp: 41,131 Records Confirmed Leaked

UP 418 288K Napoleon Corp: 41,131 records confirmed leaked from an October 29, 2025 stealer infection, the latest in this ongoing branded series.

Why This Is Dangerous

As the third confirmed Napoleon Corp file tracked recently, this release brings the combined total from this operation to well over 75,000 records. Every entry includes a plaintext password.

What Was Exposed

• Email addresses (41,131 unique accounts)
• Plaintext passwords with no encryption
• URLs tied to each compromised service

Why This Matters

Multiple files from the same operator, like this Napoleon Corp series, means your credentials could appear in more than one release if you were affected by the underlying malware campaign. Checking against just one file from this series isn't enough.

How Stealer Logs Work

The '288K' in this filename likely refers to the raw batch size before filtering, with 41,131 records confirmed as the final verified count. Operators running numbered series like UP 415 and UP 418 typically process large raw hauls down to smaller, higher quality releases, wich explains the gap between the labeled batch size and the actual confirmed record count.

Check If You Are Affected

HEROIC's free scanner checks your email against more than 400 billion (400B+) leaked records, including every confirmed Napoleon Corp release. Check now, and don't asume you're clear just because an earlier Napoleon Corp file didn't have your email.
