Xavier_Log #300 Leaked 4,518 Passwords and Emails on Jan 21

Picture 4,518 people who each just handed a stranger their email and password without knowing it. That's essentially what happened when a stealer log called Xavier_Log #300 leaked on 21-Jan-2026.

Why This Is Dangerous

Stealer logs skip the usual defenses that protect passwords, because there's nothing encrypted to break. The data inside Xavier_Log #300 was stored in plaintext, so it's usable the moment someone downloads the file.

What Was Exposed

Xavier_Log #300 contained 4,518 exposed records. Confirmed data includes:

• Email Addresses
• Plaintext Passwords
• URLs matched to each stolen login

At 4,518 records, this file represents thousands of individual accounts across countless different websites and services.

Why This Matters

It's easy to definately underestimate a number like 4,518 when it's just a statistic on a page. But scale it to real life, and it's the equivalent of a small stadium section full of people, each one now needing to change a password before someone else uses it first. Nobody knows wich accounts an attacker will try first, so acting on all of them is the safer move.

How These Leaks Start

A stealer log begins with malware quietly installed on a victim's device, often through a fake download or infected file. The malware reads through saved browser passwords, cookies, and autofill details, then compiles everything into an exportable file. That file becomes something like Xavier_Log #300, later sold or uploaded for free to a Telegram audience.
