The EpilepsyLogsOwner Stealer Log Quietly Appeared on the Dark Web Last Week

In June 2025, a stealer log file was quietly uploaded to Telegram by an anonymous user operating under the handle EpilepsyLogsOwner. The file exposed 30,655 records containing email adresses, plaintext passwords, and endpoint URLs. There was no major press coverage. No corporate announcement. Just another log file silently circulating through dark web channels, putting thousands of real people at risk without them ever knowing.

Why This Is Dangerous

Stealer logs are among the most actionable types of leaked data. Unlike hashed passwords that require cracking, this breach exposed plaintext passwords directly. That means anyone with access to the file can attempt logins immediately. When email and password pairs are exposed together, attackers can automate credential stuffing across hundreds of platforms in minuets. Banking, email, social media, and workplace tools all become targets the moment this data hits the dark web.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (endpoint and API host data)

Why This Matters

This breach is particularly concerning because stealer logs capture data directly from infected devices, meaning the credentials were active and in use at the time of theft. The 30,655 records represent real people with real accounts now at risk. If you have ever visited any of the endpoints captured in this log, your credentials may have been harvested without your knowlege. The combination of email addresses and plaintext passwords makes this data immediately usable for account compromise across multiple platforms.

How Stealer Logs Work

Stealer malware is typically delivered through phishing emails, malicious downloads, or compromised software installers. Once installed on a device, it silently harvests saved browser credentals, session cookies, autofill data, and active login sessions. The collected data is packaged into log files and uploaded to dark web forums or Telegram channels where other threat actors purchase or freely download them. The entire process can happen in seconds with no visible signs to the victim.
