The MIX Valid Hits Combolist Could Unlock Your Bank and Email

HEROIC analysts identified a small combolist called MIX Valid Hits that a Telegram user uploaded in November 2024. The file contains 162 records pairing email addresses with plaintext passwords and the URLs where each one was used. The label valid hits is combolist slang for logins that have already been tested and confirmed to work, which means every entry in this small file is more likely to be an active, usable account than a random, unverified list. Why This Is Dangerous: Because these credentials have reportedly already been checked, an attacker does not have to guess which ones still work. They can move straight to using them, and if the same password appears on other accounts, one confirmed login can be the key to several more. What Was Exposed: - Email addresses - Plaintext passwords - URLs tied to each account Why This Matters: A single working email and password pair rarely stays limited to one account. Attackers use it to try banking sites, email providers, and social media logins in sequence, since people often reuse the same password across all three. That chain reaction is how one small leak turns into account takeover, identity theft, and financial fraud. How Valid Hits Combolists Get Made: Criminals often start with a much larger, unverified combolist and run it through automated checker tools that attempt to log in to each site and flag which credentials still work. The accounts that pass become a valid hits list, smaller than the original file but considered more valuable because the success rate is higher. These curated lists are then shared or sold on Telegram channels and dark web markets.
