The 1K ValidMix5 Leak Has About as Many Records as a Small Town

HEROIC analysts identified a combolist named 1K ValidMix5 uploaded to a Telegram channel in May 2024. The file contains 1,000 confirmed records of email addresses, plaintext passwords, and the login URLs tied to each account, roughly the same number of people as a small town. Why This Is Dangerous: The name 'ValidMix' signals that whoever compiled this list already tested the logins and kept only the ones that worked. That makes this a higher-risk file than a random, unverified dump, since every credential inside is likely still active. What Was Exposed: - Email addresses - Plaintext passwords - Associated login URLs Why This Matters: A verified list of 1,000 working logins gives attackers a ready-made set of targets. If your email and password combination is in this file and reused on other accounts, criminals can use the same credentials for credential stuffing, gaining access to your email, financial accounts, or online stores and opening the door to account takeover or identity theft. How Combolist Leaks Work: A combolist pairs stolen or previously leaked emails with passwords, and a 'valid mix' file goes a step further, filtering out dead logins so only working credentials remain. These lists are usually built from older breaches or malware infections, then tested, cleaned, and shared or sold on Telegram. Check If You Are Affected: Because this file was pre-screened for working logins, it is worth checking now. HEROIC's free breach scanner checks your email against more than 400 billion leaked records, so you can confirm quickly whether you were part of the 1K ValidMix5 leak.
