The MIX COMBO List Quietly Surfaced on Telegram With 3,653 Logins

In June 2026, HEROIC analysts spotted a combolist named "MIX COMBO" being shared on Telegram. The file contained 3,653 records pairing email addresses with plaintext passwords, collected from previous breaches and repackaged into a single ready-to-use list. Why This Is Dangerous: A combolist takes credentials that have already leaked somewhere else and combines them into one file that's easy to run through automated tools. Every entry in MIX COMBO is a working email and password pair at the time it was compiled, which means anyone who reused that password on another account is exposed to more than just the original breach. What Was Exposed: The MIX COMBO list contains email addresses, plaintext passwords, and URLs associated with the accounts. Why This Matters: Combolists like this one are the raw fuel for credential stuffing attacks, where criminals automatically test stolen email and password pairs against banking sites, email providers, and shopping accounts. If a password in MIX COMBO was reused, that single leaked credential can unlock several accounts at once, opening the door to account takeover and financial fraud. How a Combolist Like MIX COMBO Works: Combolists are usually assembled by pulling credentials from older, often unrelated breaches, deduplicating them, and formatting them as email and password pairs. Attackers trade or upload these files on Telegram because they are lightweight, easy to search, and require no technical skill to use with credential stuffing tools. Check If You Are Affected: If your email might be one of the 3,653 records in the MIX COMBO list, HEROIC's free breach scanner checks it against more than 400 billion leaked records in seconds.
