How the “Good” Stealer Log Exposed 135 Login Credentials

How the "Good" Stealer Log Ended Up on Telegram

In May 2026, HEROIC analysts found a small stealer log titled "Good" shared by a user on Telegram. The file held 135 records, each pairing an email address with a plaintext password and the URL of the site the credential unlocks.

Why This Is Dangerous

Even with only 135 records, every entry in this log is a working set of credentials tied to a specific website. Because the password is stored in plain text and matched directly to a login URL, an attacker doesn't need to crack or guess anything, they can attempt to log in immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each set of credentials

Why This Matters

A small log doesn't mean small risk for the people in it. If any of these 135 individuals reused their password elsewhere, that single leaked credential can unlock email, banking, or social media accounts through credential stuffing. Attackers routinely run small logs like this one through automated login tools that test stolen passwords across hundreds of popular sites.

How Stealer Logs Work

Stealer logs are built by malware that infects a victim's computer, usually through a pirated program, fake update, or malicious attachment. The malware quietly collects saved browser passwords and autofill data, sends it to the attacker, and the resulting file is shared or sold in Telegram channels, exactly where HEROIC analysts found this one.
