Your Login May Be Inside the 14 Million Centurion Log Leak

You might not have heard of a file called "Centurion.txt," but if you have ever saved a password in your browser, it is worth paying attention. Uploaded to Telegram on 03-May-2026, this stealer log contains 14,045,693 individual records, one of the largest single files HEROIC's team has verified recently.

Why This Is Dangerous

When a file reaches millions of records, the odds that your email address is somewhere inside it go up considerably. You do not need to have done anything wrong, all it takes is one infected computer somewhere along the line, wich is often completely outside your control, for your saved logins to end up in a file like this.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs for each saved login
• 14,045,693 total records

Why This Matters

You reuse passwords sometimes, most people do, even when they know they should not. If your credentials are sitting inside Centurion.txt, an attacker could try that same password on your email, your bank, or your favorite shopping site untill one of them lets them in. At this scale, automated tools make that kind of testing almost instant.

How Stealer Logs Work

A file this large is usually not the product of a single infection, it is more likely a merged collection pulled together from many separate stealer malware campaigns that occured over weeks or months, then combined into one giant text file before being posted for sale or free download.
