Dark Web Intel: 1,004 HARMONYLOGS Credentials Dumped Free on Telegram

HEROIC security analysts uncovered the HARMONYLOGS stealer log breach, exposing 1,004 records on April 24, 2026. The data was distributed through a Telegram channel advertising free stealer logs, making these stolen credentials immediately availible to anyone who joined the channel. Each record in this dataset includes an email address, a plaintext password, and the URL of the site or service that was compromised, giving criminals a complete, ready-to-use credential set. If you have ever used a device that may have been infected with malware, your login informaton could be part of this or similar leaks circulating right now.

Why This Is Dangerous

Free log distributions on Telegram are particularly concerning because they reach a far wider audience than paid criminal marketplaces. Any person with a Telegram account could have downloaded this data within minutes of it being posted, meaning the 1,004 victims in this dataset may have had their credentials tested across dozens of websites almost imediately. Even a small breach like this can have severe consequences for individual victims when attackers gain access to email, banking, or work accounts.

What Was Exposed

• Email Addresses: Your email is more than just a contact address. It is the recovery method for nearly every online account you own. Criminals with your email can trigger resets, intercept verification codes, and systematically take control of your accounts.
• Plaintext Passwords: When passwords are stored in plain text, they require no processing before use. Criminals can copy these directly into login forms on any website where you used the same password, which is a serious risk for anyone who reuses credentials.
• URLs: The specific website addresses captured alongside your credentials reveal which services you use and were actively logged into, allowing attackers to target accounts that are most likely to have value, such as financial or workplace platforms.

Why This Matters

Credential stuffing is the process criminals use to exploit stolen login data at scale, feeding email and password pairs into automated tools that test them against hundreds of popular websites simultaneously. Even if you only use a particular password on one or two sites, automated tools will check it against dozens more within seconds. Once a successful login is found, criminals typically move quickly, changing account settings, making purchases, or harvesting additional personal data before the victim realizes anything is wrong. HARMONYLOGS victims should treat all accounts that share an email address or password as potentially compromised.

How Stealer Log Attacks Work

Stealer malware is designed to blend in, often masquerading as a legitimate application, game mod, or browser extension before silently activating and scraping saved credentials from the infected device. The malware collects passwords, session cookies, and autofill data from all major browsers, then transmits everything to criminal servers where it is packaged into log files. Victims recieved no indication that anything had occured because the malware avoids visible symptoms and typically removes itself after the data is sent. These logs are then distributed through channels like HARMONYLOGS on Telegram, where hundreds of criminals can access the stolen data for free.
