3,253 Plaintext Passwords From the MATRIX FREE LOGS1 Dump Surfaced on Telegram

In August 2023, HEROIC analysts identified a stealer log file labeled "MATRIX FREE LOGS1" that had been uploaded to Telegram and shared publicly among threat actor communities. The file contained 3,253 records harvested from infected devices, including email addresses, plaintext passwords, and URLs where those credentials were in active use at the time of infection. The "FREE LOGS" label in the file name indicates this data was distributed at no cost, meaning it reached an especially wide audience of potential attackers.

Why Free Stealer Log Distributions Are Particularly Dangerous

When threat actors sell stealer logs privately, access is limited to buyers with the resources to pay. When they release them for free, the audience expands dramatically. Any Telegram user with access to the channel can download the file, and that means thousands of potential attackers could have your credentials. The MATRIX FREE LOGS1 file was designed for maximum distribution from the start.

Free log releases are also often used as promotional material by stealer log operators who want to demonstrate the quality of their data to potential buyers. The fact that this file has been circulating since August 2023 means it has had years to be absorbed into combolist databases, credential stuffing tools, and other downstream attack infrastructure.

What Was Exposed in the MATRIX FREE LOGS1 Stealer File

• Email Addresses: Real account identifiers that allow attackers to target specific individuals across dozens of platforms.
• Plaintext Passwords: Unencrypted credentials pulled from browser storage on infected devices, usable immediately without any cracking step.
• URLs: The exact websites where each credential pair was active, giving attackers a prioritized list of which accounts to target first.

Why the MATRIX FREE LOGS1 Data Is Still a Risk Years Later

Data from 2023 does not stop being dangerous just because time has passed. Most people never change their passwords unless forced to. Stealer log credentials from two years ago are still valid for millions of accounts because the victims do not know they were ever exposed. In fact, older free log data that has been widely distributed is more dangerous in some ways because it has had more time to be ingested into automated attack tools.

Credential stuffing operations regularly recycle older datasets against new targets. A credential harvested in 2023 and ignored may still unlock your email account, your bank portal, or your social media profile today. Account takeover, identity theft, and unauthorised purchases are all realistic outcomes from data in files like this one. It can definitly happen to anyone who has not audited their exposure.

How the MATRIX Stealer Log Operation Collected This Data

The MATRIX naming convention suggests an organized stealer log distribution channel operating on Telegram. Information stealer malware, including variants like RedLine, Raccoon, and others, is installed on victim devices through phishing emails, fake software downloads, and trojanized browser extensions. Once running, the malware extracts saved passwords from browsers like Chrome and Firefox, packages them alongside the associated email addresses and URLs, and sends the results back to the operator.

Files are then bundled into numbered log releases. The "LOGS1" suffix indicates this is the first in a series, suggesting the MATRIX channel produced multiple releases. Each file represents a distinct batch of infected machines, and each one that gets shared publicaly becomes a permanent part of the dark web data ecosystem. Once circulated freely, there is no way to recall it.

Search Your Email Against the MATRIX FREE LOGS1 Data

HEROIC's breach scanner indexes stealer log files like MATRIX FREE LOGS1 into a database of over 400 billion exposed records. If your email address appeared in this file, a free scan will surface it in under a minute and show you exactly what data was exposed.

Even if you changed your passwords at some point since 2023, it is worth confirming that this file did not capture you. If it did, you will want to make sure your current credentials are not variations of what was stolen. Run your free scan now and check your exposure history.
