The “fb5” Stealer Log Just Leaked 20,239 Passwords Online

The "fb5" Stealer Log Leaked 20,239 Records

HEROIC analysts identified a stealer log named "fb5," uploaded by a Telegram user and dated 26-Apr-2024. The file contains 20,239 records made up of email addresses, plaintext passwords, and the URLs those credentials were captured from.

Why the "fb5" Stealer Log Is Dangerous

Every password in this file sits in plaintext, so there is no encryption for an attacker to work around. Each one is also matched to a specific URL, telling an attacker exactly which site the login belongs to. Put simply, this file hands over more than 20,000 working logins on a plate.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the exact site each login belongs to

Why This Matters

Anyone in this log faces an immediate account takeover risk, since the exposed password works as-is against the linked site. Because the batch is large, that risk touches a lot of people at once, and anyone who reused a password elsewhere opens the door to credential stuffing on other accounts too.

How Stealer Logs Work

Stealer logs are produced by malware that infects a device and silently copies whatever the browser has saved, including passwords, autofill entries, and site URLs. That stolen data is bundled into a file and delivered to the attacker, who then shares or sells it, often on Telegram, exactly where this one was found.

Check If You Are Affected

With over 20,000 records in this leak, checking your exposure is a smart move. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you immediately if you were affected.
