Hotmail Users Targeted: 320 Valid Accounts Leaked in Stealer Log

What Happened in the "Hotmail valid." Stealer Log Leak

In June 2026, a Telegram user uploaded a file labeled "Hotmail valid.", exposing 320 records confirmed to be active Hotmail-linked logins pulled from malware-infected devices. The dataset includes email addresses, plaintext passwords, and the URLs tied to those accounts.

Why This Is Dangerous

The word "valid" in the file name is a warning sign on its own. It means whoever compiled this list already tested the credentials and confirmed they work, so every one of these 320 accounts is a live target rather than a stale, outdated login.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Pre-verified credentials let attackers skip straight to account takeover, no guessing required. From there, attackers can attempt credential stuffing against other services using the same email and password, mine the inbox for personal information used in identity theft, and target any linked financial accounts for fraud.

How Stealer Logs Get Marked as "Valid"

After stealer malware harvests credentials from an infected device, criminals often run a validation pass, quietly logging into each account to confirm the password still works before selling or sharing the list. Files tagged "valid" like this one command more attention on Telegram and dark web forums because buyers know the accounts are ready to use immediately.

Check If You Are Affected

If your Hotmail or Outlook address is part of this list, the confirmed working password means the risk is immediate rather than theoretical. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, including verified stealer log entries like this one, so you can find out right away and change any reused passwords.
