Your Hotmail Login May Be Exposed: 1,426 Accounts in New Combolist

In June 2025, HEROIC analysts identified a combolist titled 'Hotmail channel public' uploaded by a Telegram user. The file contained 1,426 records pairing email addresses with plaintext passwords, along with the URLs those logins were used on, focused specifically on Hotmail style accounts and tied primarily to users in the United States.

Why the Hotmail Channel Public Leak Is Dangerous

Because this combolist was compiled around Hotmail accounts specifically, it gives attackers a focused set of targets rather than a random mix of logins. The passwords are stored in plaintext, so no cracking is required, and the included URLs point straight to where each login can be used.

What the Hotmail Channel Leak Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each account

Why This Matters

Email accounts like Hotmail are often the key that unlocks everything else, since password resets for banking, shopping, and social media accounts typically go through email. With 1,426 credential pairs exposed, this leak puts attackers one step away from taking over not just an inbox but every account tied to it, opening the door to identity theft and financial fraud.

How Combolists Like This Are Built

A combolist is a compiled file of email or username and password pairs, often gathered from older breaches, malware infections, or manual collection, then organized by email provider and shared publicly on Telegram channels. Naming this file 'public' suggests it was released openly rather than sold privately, making it especially easy for less sophisticated attackers to access and use.

Check If You Are Affected

If you used a Hotmail account around June 2025, it is worth checking whether your credentials appear in this leak. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, so you can find out quickly whether your password needs to change.
