Combo Mix 4 Stealer Log Leaks 46,564 US Logins and Passwords

On January 18, 2023, a stealer log called Combo Mix 4 was uploaded to a Telegram channel that trades stolen login data. The file is attributed to the United States and contains 46,564 records made up of email addresses, plaintext passwords, and URLs, all harvested directly from infected devices.

Why US-Based Accounts Are Common Targets in Combo Mix 4

Combolists like this one are typically built by combining stolen credentials from a shared region or set of infected devices, and this one is tagged to the United States. That means the accounts inside, banking logins, retail accounts, email addresses, are likely tied to US-based services that criminals already know how to target with familiar phishing and fraud tactics.

What Was Exposed in This Stealer Log

• Email addresses linked to US accounts
• Plaintext passwords with no encryption protecting them
• URLs showing exactly which sites each login unlocks

Why This Matters for US Account Holders

Because the passwords are stored in plaintext next to a working email and the site they unlock, criminals can move directly from this file into credential stuffing attacks, trying the same login across banking, retail, and email platforms. A reused password can lead straight to account takeover, identity theft, or financial fraud.

How a Combolist Like Combo Mix 4 Comes Together

Infostealer malware infects a device, often through a cracked program or fake download, and quietly pulls saved passwords and autofill data out of the browser. Multiple stolen logs get merged into a single combolist like this one, then traded on Telegram to buyers looking for a large batch of working credentials in one place.
