The 39K USA-EU-Asia-RU Corp MIX Leak Exposed Passwords and Emails

HEROIC analysts identified this combolist in late May 2026 after a Telegram user uploaded it publicly. The file contains 37,447 records combining email addresses, usernames, and plaintext passwords, along with the URLs of the sites those credentials were originally used on. Based on the file's own naming, the data appears to mix accounts from the United States, Europe, Asia, and Russia, spanning corporate and personal logins rather than one single company or platform. Why This Combolist Is Dangerous: Because every password in this file was stored and leaked in plaintext, anyone who downloads it can log in to an account immediately, without needing to crack or decrypt anything. Attackers use combolists like this to test stolen email and password pairs against banking sites, email providers, and workplace logins in bulk, hoping people reused the same password across services. What Was Exposed: - Email addresses and usernames - Plaintext passwords - URLs tied to each set of credentials Why This Matters: If any of these credentials match a password you still use, an attacker can walk straight into that account, or any other account where you reused the same password. That opens the door to credential stuffing attacks, account takeover, and downstream fraud, especially since work accounts appear mixed in with personal ones in this file. How Combolist Leaks Like This Happen: A combolist is a compiled text file pairing usernames or emails with passwords, usually pulled together from older breaches, phishing kits, or malware logs and repackaged for resale or free distribution on Telegram. Unlike a single company breach, a combolist can combine credentials from dozens of unrelated sources, which is why the URLs field matters: it shows which site each password pair was originally used on.
