The 577k Mix Combo UHQ Data Just Went Public on the Dark Web

HEROIC analysts identified this stealer log on 06-Feb-2025. The breach exposed 352,822 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as 577k Mix Combo UHQ uploaded by a Telegram User.

Why This Is Dangerous

With 352,822 stolen email and password pairs now publicly available, this dataset poses a massive, immediate risk. All credentials are in plaintext with no encryption to overcome. The included URLs identify which services were targeted, giving anyone who downloads this dataset a ready-made list of accounts to attack. Datasets of this size are frequently used to launch large-scale automated credential stuffing campaigns.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

When a credential dataset of this scale goes public, it dramatically increases the risk of account takeovers because the data becomes accessible to a much larger pool of criminal actors. Automated tools can test hundreds of thousands of stolen credentials against major platforms in a matter of hours. This breach puts affected users at serious risk of account takeover, identity theft, and financial fraud.

How Stealer Logs Work

Stealer logs are files generated by malware installed on victims' computers without their knowledge. The malware captures login credentials as they are entered, pulls saved passwords from browsers, and records the URLs of websites visited. These credential files are bundled and shared through Telegram channels and dark web forums, where they are further distributed across criminal networks.
