Identity Theft Just Got Easier After the ‘Valid Hotmails’ Leak

In October 2024, HEROIC analysts identified a stealer log named "VALID HOTMAILS," uploaded by a Telegram user, exposing 387 records made up of email addresses, plaintext passwords, and the URLs each login was used on.

Why the Word "Valid" Changes the Risk

Most stolen credential dumps are a mix of working and dead logins, accounts that were changed, closed, or never valid to begin with. A file explicitly labeled "valid" means someone has already tested these Hotmail logins and confirmed they still work, which strips away the guesswork for an attacker and turns identity theft from a long shot into a near-certain outcome for the people in this file.

What Was Exposed

• Confirmed working Hotmail email addresses
• Plaintext passwords, stored with no encryption
• URLs identifying the exact login page each credential belongs to

Why This Matters

Because these accounts are verified as live, anyone in this file faces an immediate risk of account takeover rather than a theoretical one. A compromised Hotmail inbox can be used to reset passwords on banking, shopping, and social media accounts, opening the door to fraud and identity theft well beyond the original email account.

How Attackers Verify Stolen Logins Before Selling Them

Stealer malware first captures raw usernames, passwords, and URLs from infected devices. Before a file gets labeled "valid," someone runs automated checking tools that attempt to log into each account, filtering out any that fail. What remains is a smaller, more valuable list of confirmed working logins, which is exactly what makes a file like this one more dangerous than an unverified dump of the same size.

Check If You Are Affected

If you use a Hotmail account, it is worth checking now rather than waiting. HEROIC's free breach scanner checks your email address against a database of more than 400 billion breached and leaked records, so you can confirm your exposure in seconds and secure your account.
