2,177 Hotmail Logins Leaked by Kiotaka_Support on Telegram

2,177. That's the exact number of Hotmail accounts exposed when a Telegram user known as Kiotaka_Support uploaded a stealer log on 15-Oct-2025. HEROIC's dark web tracking caught the file shortly after it went up, still fresh and largely untouched by other collectors.

Why This Is Dangerous

2,177 might sound small compared to million-record mega-leaks, but each one of those records is a complete, working login: email, plaintext password, and the exact URL it connects to. Nothing about that combination is hard for an attacker to use.

What Was Exposed

• 2,177 total records exposed
• Email Addresses (Hotmail)
• Plaintext Passwords
• URLs for each account

Why This Matters

Because this file is relatively fresh, the odds that these 2,177 passwords still work are higher than in older leaks. Attackers know this too, wich is why freshly uploaded stealer logs tend to get exploited faster than files that have been circulating for months.

How Stealer Logs Work

Uploaders like Kiotaka_Support typically don't write the malware themselves, they collect logs from infostealer infections, sometimes buying access from others, and repackage them for distribution. The malware itself infects a device quietly, grabs saved browser credentials, and reports back before the victim even notices anything occured.

Check If You Are Affected

Since this leak is recent, it's worth checking sooner rather than later. HEROIC's free breach scanner compares your email against over 400 billion exposed records, so you'll know right away if you were among the 2,177 affected.
