Stealer Log Alert: url_log_pass0 Leaks 806,714 Credentials

A stealer log named url_log_pass0 surfaced on Telegram in May 2026, and HEROIC analysts confirmed it holds 806,714 exposed records of real login data.

Why This Is Dangerous

The name of this file is almost a description of what is inside, urls, logins, and passwords bundled together in one convenient package. That convenience works both ways though, its just as easy for an attacker to use as it would be for you to recieve a warning about it.

What Was Exposed

• 806,714 total records
• Email addresses
• Plaintext passwords
• URLs for each saved login

Why This Matters

Because everything is stored in plaintext, there is no delay between an attacker downloading this file and putting the credentials to use. A breach like this occured because a malware infection went unnoticed long enough to harvest saved data from a browser.

How Stealer Logs Work

This kind of leak starts with malware quietly installing itself on a victim's device, usually hidden inside a free download or a cracked program. From there it scans the browser, grabs every saved password and cookie, and imediately sends it back to the attacker, who then packages it up and shares it, exactly as happened with url_log_pass0.
