On June 23, 2025, a compact but revealing file called hotmail_20250623_105855 uploaded by a Telegram User surfaced, containing 1,516 login records lifted straight from infected devices in the United States.


Why This Is Dangerous

Even a smaller file like this one carries real weight. Every one of the 1,516 entries is a live email and password pair, not a random guess, wich means criminals don't need to beleive anything works, they just try it and see.


What Was Exposed

  • 1,516 total records
  • Email Addresses
  • Plaintext Password
  • URLs linked to each account

Why This Matters

Hotmail and Outlook inboxes are often the master key to someone's whole online life, password resets for banking, shopping and social media all flow through email. Once an attacker gets in, they can lock the real owner out completely, and it may take days or weeks untill the victim even notices something is wrong.


How Stealer Logs Work

This file was built the same way most stealer logs are, malware sitting on a victim's computer quietly recorded login pages, usernames and passwords as they were typed, then exported everything into one document. That document eventually landed on Telegram, free for anyone to grab.
