One Telegram Post, 1,190 Accounts: Inside the 1.5K Hotmail Combo Leak

In June 2026, HEROIC analysts found a combolist titled "1.5K Hotmail Combo list Full Valid" on Telegram. Despite the round number in the name, the file actually contained 1,190 records pairing email addresses with plaintext passwords, labeled by the uploader as fully verified. Why This Is Dangerous: When an uploader marks a list as full valid, it usually means every credential has been tested against a live login page before the file was shared. That verification step removes the guesswork for an attacker, turning a small file into a reliable set of working logins. What Was Exposed: This Hotmail combo contains email addresses, plaintext passwords, and URLs tied to the accounts. Why This Matters: A confirmed working Hotmail login is valuable because email accounts are often the recovery point for banking, shopping, and social media accounts. Someone with access to this list could reset other passwords, intercept codes sent by email, or use the account to run further scams. How a Full Valid Combolist Is Built: Attackers gather credentials from earlier breaches, then run them through automated checking tools that log into the target service and confirm which pairs still work. Only the working logins make it into the final file, which is why full valid lists tend to be smaller but more dangerous than raw, unchecked dumps. Check If You Are Affected: If you use a Hotmail account, take a moment to check it. HEROIC's free breach scanner searches more than 400 billion leaked records to show you if your email and password have already been exposed.
