630 Hotmail Email and Password Pairs Leaked From a Telegram Combolist

HEROIC analysts identified a small file labeled hotmail valid, uploaded to a Telegram channel on March 1, 2025. It contains 630 records, each pairing a Hotmail email address with a plaintext password and the URL the login was used on. Why This Is Dangerous: The word valid in the file's name signals that these logins were checked and confirmed to work before being shared. A small file of confirmed working credentials can do just as much damage as a larger unverified one, since every entry is ready to use immediately. What Was Exposed: All 630 records in this file share the same three fields. - Hotmail email addresses - Plaintext passwords - URLs tied to each login Why This Matters: Even a file this small puts the people in it at real risk of account takeover, especially if their Hotmail password was reused on banking, shopping, or social media accounts. Attackers don't need thousands of records to cause harm, just one working match to your other accounts. How a Combolist Like This Works: Combolists are lists of email-or-username and password pairs, often gathered from older leaks or stealer malware and checked for validity before being shared on Telegram. Smaller, verified lists like this one are frequently traded quickly because every entry has already been confirmed to work. Check If You Are Affected: Run your Hotmail address through HEROIC's free breach scanner, which checks more than 400 billion leaked records, to see if you're one of the 630 people in this file.
