The 1.800 HOTMAIL Leak Holds More Records Than a Small Village

HEROIC analysts flagged a combolist titled "1.800 HOTMAIL" that surfaced on Telegram in October 2024. The file contains 1,443 records pairing email addresses, most tied to Hotmail accounts, with plaintext passwords and the login URLs they connect to.

Why This Is Dangerous

Because the file focuses specifically on Hotmail-linked logins, it gives attackers a targeted set of working credentials for one of the world's most widely used email providers. Email accounts are often the master key to a person's digital life: whoever controls the inbox can reset passwords for banking, shopping, and social media accounts tied to that address.

What Was Exposed

• Email addresses (largely Hotmail accounts)
• Plaintext passwords
• Associated login URLs

Why This Matters

1,443 records may sound small next to the leaks that make headlines, but scale isn't the only measure of risk. Every entry represents a real inbox that attackers can try to unlock, and a compromised email account is often the first domino in a chain that leads to account takeover, financial fraud, or identity theft.

How Combolists Work

A combolist bundles email/username and password pairs into a single file, typically compiled from older leaks and stealer malware output rather than a fresh hack of one company. Sellers and Telegram channels package these lists by theme, in this case by email provider, so buyers can target a specific audience, here, Hotmail users, more efficiently.

Check If You Are Affected

Search your email address in HEROIC's free breach scanner, which checks against more than 400 billion compromised records, to see whether your Hotmail account appears in this leak or any other exposure on record.
