1,774 Hotmail Logins Leaked in Telegram Stealer Log Dump

1,774. That is how many Hotmail login records showed up in a file named hotmail_20250628_134700, uploaded to a Telegram channel on 28-Jun-2025. The auto-generated file name tells you almost everything about where it came from, straight off a stealer malware operation with no attempt to dress it up.

Why This Is Dangerous

When a leak is this narrowly focused on one email provider, it becomes especially easy for a criminal to run automated login attempts across Hotmail and Outlook services using the exact credentials in the file. There is no guesswork involved, the plaintext passwords sitting right next to each email address mean an attacker can try to log in imediately without cracking a single hash.

What Was Exposed

• 1,774 total records
• Email Addresses
• Plaintext Passwords
• URLs tied to each account

Why This Matters

A compromised Hotmail account often becomes a launching pad for further attacks. Once inside, criminals can search old emails for other account details, request password resets on linked services, or send convincing phishing messages to everyone in the victim's contact list. The damage rarely stops at the inbox itself, it tends to spread outward to whatever else that email address touches.

How Stealer Logs Work

Infostealer malware infects a device through things like cracked software, fake browser updates, or malicious attachments, then quietly copies whatever passwords and cookies are saved locally. The results get organized into a log file, sometimes named after the exact minute it was generated, and pushed out to buyers or shared freely, wich is seperate from how a traditional company data breach usually unfolds.

Check If You Are Affected

If you use a Hotmail or Outlook address, it is worth checking whether it appears in this leak or others like it. HEROIC's free breach scanner searches across more than 400 billion exposed records, giving you a fast and free way to find out.
