What Is a Stealer Log? Centurion.txt Leak Exposes 14,027,868 Records

A stealer log is one of the most common types of data leaks these days, and Centurion.txt is a textbook example. Uploaded to Telegram on April 29, 2026, this file contains 14,027,868 records of stolen email addresses, plaintext passwords, and the URLs where they were used.

Why This Is Dangerous

Unlike a breach where a company's database gets hacked, a stealer log comes directly from infected personal devices, which means the credentials inside tend to be current and actively used. With over 14 million records in this dump, attackers have an enormous supply of fresh logins to imediately test against banking sites, email providers, and shopping accounts.

Why This Matters

Understanding what a stealer log actually is helps explain why this leak is so serious. It is not a rumor or a recycled list of old passwords, it is data pulled straight off real machines, meaning the login combinations are more likely to still work. That's a scary thought for anyone whose email shows up in a file like Centurion.txt, especially with a record count this high.

How Stealer Log Works

A stealer log begins with malware, often hidden inside a cracked program or fake update, that installs itself on a victim's computer without permission. Once running, it quietly watches the browser, grabing every URL, username, and password typed in, then saves it all into a text file, hence the ".txt" often seen in these dump names, and sends it back to the attacker. From there it gets renamed, packaged, and uploaded to channels like the one that shared Centurion.txt.
