Inside the Xavier_Log Stealer Logs: How 3,555 Passwords Leaked

HEROIC analysts identified a stealer log labeled "Xavier_Log - 200 Xavier_Group free" that was uploaded to a Telegram channel on 1 August 2026. The file contains 3,555 records made up of email addresses, plaintext passwords, and the URLs of the login pages those credentials belong to.

Why This Is Dangerous

Advertised as a free release from a group calling itself Xavier_Group, this stealer log gives away 3,555 working credential sets at no cost. Because each password is stored in plaintext and matched to the exact site it unlocks, anyone who downloads the file can start testing logins immediately, no technical skill required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Anyone in this file faces a real risk of account takeover, especially if they reuse the same password across multiple sites. Because the log is being given away for free, it is likely to be downloaded and tested by far more people than a paid list would be, increasing the odds that any given account gets targeted through credential stuffing.

How Stealer Logs Work

Stealer logs like this one are produced by malware that infects a victim's device, often through pirated software, fake game cheats, or malicious downloads. Once installed, the malware scans the browser for saved passwords, autofill data, and active login sessions, then packages everything into a single file. Groups like the one behind this log then distribute these files, sometimes for free to build a reputation, in Telegram channels and dark web forums.
