Inside the MIX_2 Combolist: How 4,876 Logins Got Harvested

On November 29, 2024, a Telegram user uploaded a combolist named "MIX_2," pulled together from multiple sources rather than a single email provider. HEROIC analysts confirmed the file contains 4,876 records, each combining an email address, a plaintext password, and a source URL.

Why a "Mixed" Combolist Is Harder to Pin Down, and Just as Dangerous

Unlike lists built around one email provider, a mixed combolist like MIX_2 pulls credentials from a variety of sites and services. That variety makes it more versatile for attackers, since it can be used to target multiple platforms at once, but it also means the original source of each specific credential is often obscured.

What Was Exposed in the MIX_2 List

• Email addresses
• Plaintext passwords
• Source URLs tied to each credential

Why This Matters

Because passwords are stored in plaintext, no cracking is needed before this data can be used. For the 4,876 people in this file, the risk lies in password reuse: attackers feed mixed combolists into automated tools that test the same email and password combination across dozens of unrelated sites, looking for any account where it still works.

How Mixed Combolists Like MIX_2 Get Compiled

Mixed combolists are typically assembled by pooling smaller lists, breach dumps, and stealer log outputs from different sources, then deduplicating and verifying them before sharing. The "_2" in this file's name suggests it's part of a series, likely a second batch from the same collector or Telegram channel.
