The Mix New Part 4: 145,864 Passwords and Emails Leaked Online

HEROIC analysts identified this stealer log on 19-Dec-2022. The breach exposed 145,864 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as Mix New Part 4.

Why This Is Dangerous

With nearly 146,000 plaintext email and password pairs now circulating among cybercriminals, this data is immediately actionable. Attackers do not need to decrypt or crack anything. Every email address in this dataset is a potential target for account takeover on any site where the victim used the same password. The accompanying URLs further reveal which platforms each victim used, giving attackers a direct roadmap for unauthorized access.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

Credential data from breaches like Mix New Part 4 circulates through criminal marketplaces for months or years after the initial leak. Attackers use these stolen pairs in bulk credential stuffing campaigns that target email providers, online retailers, banks, and streaming services. A password reused across multiple sites means a single leak can cascade into multiple account takeovers, putting your identity, finances, and personal data at risk.

How a Stealer Log Works

A stealer log is the output of malware designed to harvest login credentials from infected devices. After gaining access to a computer through a malicious download or phishing link, the malware silently collects saved passwords and browser session data. This information is compiled into a log file and shared in private online channels, where other criminals access it to carry out attacks.
