Identity Theft Risk Grows After the Mix Combo3 Credential Leak

What HEROIC Analysts Found

In November 2024, HEROIC analysts identified a combolist file labeled "Mix Combo3," uploaded to a Telegram channel. The file contained 19,822 records pairing email addresses with plaintext passwords, along with the URLs of the sites those logins belong to.

Why This Is Dangerous

Each entry in this file gives an attacker everything needed to log in immediately: the email, the password in plain, readable text, and the exact site the login belongs to. There is no password cracking involved, just a direct match ready to be tested.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each login to the site it belongs to

Why This Matters

Gaining access to someone's email account is often the first step toward much bigger problems. From an inbox, an attacker can reset passwords on banking, shopping, and social media accounts, intercept verification codes, and piece together enough personal details to attempt identity theft. Because this file blends credentials from multiple sources, as the "mix" in its name suggests, the risk of reused passwords opening several doors at once is higher than usual.

How Combolists Work

A combolist is a compiled file of email or username and password pairs, typically gathered from previous breaches, stealer logs, or leaked databases and merged into one package. A "mix" combolist pulls credentials from several different sources into a single file, which is then run through automated tools that test each pair against live login pages to confirm which ones still work.
