The EclipseLogs Dump Put Tech Credentials for 20,938 Users on Telegram

HEROIC Analysts Discover 20,938 Compromised Records in EclipseLogs 411count Stealer Log

In July 2025, HEROIC analysts flagged a stealer log file named EclipseLogs 411count, uploaded to Telegram on July 2, 2025. The log exposed 20,938 records containing email addresses, plaintext passwords, and URLs collected from infected devices in the United States. Stealer logs of this type capture credentials at the moment they are typed or retrieved from a browser, giving attackers an unusually clean and actionable dataset. The EclipseLogs dump is a textbook example of how infostealer malware operattes in the wild and ends up distributed through messaging platforms.

Why This Data Puts Victims at Immediate Risk

When plaintext passwords are leaked alongside the URLs where they were used, criminals do not need to do any additional work to exploit the data. They already know which site, which account, and which password. This type of package is used to launch instant account takeover attacks across email providers, SaaS platforms, cloud services, and internal business tools. For developers and technical users, the URLs in a stealer log often reveal access to code repositories, CI/CD pipelines, and API management consoles, making the exposure far more damaging than a typical consumer credential leak.

What Was Exposed

The EclipseLogs 411count breach exposed the following categories of data for over 20,000 individuals:

• Email Addresses
• Plaintext Passwords
• URLs (the exact web services where credentials were captured)

Why This Matters: The Ripple Effect of Stolen Credentials

Even one compromised credential from a stealer log can trigger a chain of account takeovers. Criminals use credential stuffing tools that automatically test stolen logins across dozens of platforms. A single email and password pair from EclipseLogs 411count could unlock a victim's email inbox, which then gives attackers the ability to reset passwords on every other account linked to that address. From there, identity theft, financial fraud, and unauthorized access to workplace systems become very real possibilities. The fact that all passwords in this dump were in plaintext means no cracking or decryption step is required.

How Stealer Logs Are Built and Distributed

The name EclipseLogs is a branding choice made by the operator of the infostealer campaign. Infostealers are malware programs installed on victims' computers through phishing links, trojanized software installers, or malicious browser extensions. Once running, the malware harvests saved browser credentials, cookies, and session tokens, then packages everything into a structured log file. These files are then sold on underground markets or uploaded directly to Telegram channels where other criminals can download and use them. The victim typically has no idea anything occured until fraudulent activity shows up on their accounts. HEROIC analysts recieve these files through dark web monitoring pipelines and work quickly to index the records so victims can be alerted.

Check If Your Data Was Caught in This Leak

If you use any online services from a U.S.-based device, your credentials may have been seperate from your knowledge and included in a stealer log like EclipseLogs 411count. HEROIC's free personal data scanner checks your email address against more than 400 billion exposed records, including stealer logs from Telegram and dark web forums. A scan takes under a minute and can reveal which of your accounts may already be in criminal hands. Do not assume you are safe just because you did not recieve a breach notification. Stealer log victims rarely do.
