The Combo Mix 2 Gave Hackers What They Need to Access Real Accounts

HEROIC analysts identified this stealer log on 18-Jan-2023. The breach exposed 46,651 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as Combo Mix 2 uploaded by a Telegram User.

Why This Is Dangerous

The Combo Mix 2 breach contains over 46,000 plaintext email and password pairs drawn from multiple sources. This type of mixed credential file gives attackers everything needed to attempt logins on email accounts, banking portals, social media platforms, and shopping sites, without any additional tools or effort.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

Credential files of this size are used to power large-scale account takeover campaigns. Automated tools cycle through all 46,651 login pairs across dozens of websites simultaneously. Even a low rate of success results in thousands of compromised accounts, leading to identity theft, unauthorized financial transactions, and loss of access to personal data.

How Stealer Logs Work

Combo files like this one are assembled from stealer logs collected by malware running on infected computers. The malware copies credentials from browsers and applications, sends them to the attacker, and the data is compiled into files that are circulated through Telegram channels and dark web markets where criminals use them for large-scale account fraud.
