19,797 Users Targeted in the Mix Combo 2 Stealer Log Breach

HEROIC Analysts Uncover the Mix Combo 2 Stealer Log

On November 19, 2024, HEROIC's threat intelligence team identified a stealer log titled "Mix Combo 2" uploaded to Telegram by an anonymous user. The file contained 19,797 records, each pairing an email address with a plaintext password and the URL of the site the credentials were used on.

Why the Mix Combo 2 Data Puts Nearly 20,000 Accounts at Risk

This is not a leaked customer database from a single company. It is a stealer log, meaning the credentials were pulled directly off infected computers by malware, then combined into one large file. Because the theft happens on the victim's own device, the passwords are current and were working at the time they were captured, which makes this kind of data especially valuable to criminals looking for accounts they can log into right away.

What Was Exposed in the Mix Combo 2 Log

• Email addresses used to log into online accounts
• Plaintext passwords tied to those accounts
• The website URLs where each set of credentials was used

Why This Matters If You Are One of the 19,797 Affected

With a working password and its matching login URL in hand, an attacker can attempt account takeover immediately, no cracking or guessing required. If any of the 19,797 people in this log reused the same password on other sites, they are also exposed to credential stuffing, where automated tools try the same email and password combination across banking, email, and shopping accounts until one works.

How the Mix Combo 2 Log Was Harvested

Stealer logs like Mix Combo 2 come from infostealer malware, which typically spreads through cracked software, fake downloads, or phishing links. Once it infects a device, the malware reads saved passwords and autofill data straight out of the browser and exports them into a file. Criminals then combine logs from many infected victims into one release, like Mix Combo 2, and circulate them on Telegram channels for free or for sale.
