Since 18-Jun-2025, a file called Mixed_Leak_20250618_030504 has been sitting in a Telegram channel accumulating downloads. In that time, 3,167 people's email addresses and plaintext passwords have been available to anyone who joined that group, with no expiration date and no way to pull it back once shared.


Why This Is Dangerous

Time works against the victims in a leak like this one. The longer the file circulates, the more copies get made, the more people forward it to other channels, and the harder it becomes to ever fully contain. What started as one upload on a single date becomes untraceable within days as it spreads across the platform.


What Was Exposed

  • 3,167 email addresses tied to compromised accounts
  • Corresponding passwords left in plaintext form
  • URLs showing the specific site tied to each login

Why This Matters

Every day this data stays online is another day someone hasn't changed their password. Attackers frequently wait before using stolen credentials, betting that victims will asume enough time has passed that nothing bad happened, which makes delayed account takeovers particularly effective against people who never got the memo in the first place.


How Stealer Logs Work

Data like this typically comes from malware bundled into a fake system optimizer or PC cleaner tool advertised as fixing slow computers. Once a victim installs and runs it, the program secretly reads saved browser credentials and session data, then exports it into a log file that eventually gets shared or sold, often ending up exactly where this one did.
