Mix TXTVALID Leak: Is Your Password in This 3,639-Record Dump?

In late April 2026, a file known as "Mix TXTVALID" surfaced on Telegram, uploaded by a user sharing stolen credential data. The file is a stealer log, a batch of information pulled directly off infected computers rather than stolen from a company's servers. It contains 3,639 records, each pairing an email address with a plaintext password and the website URL the login was used on.

Why This Is Dangerous

Stealer logs are some of the most immediately useful data for criminals because the passwords inside them are not hashed or encrypted. They are stored in plaintext, meaning anyone who downloads the file can read your actual password and try it on other accounts right away. Because this log was shared openly on Telegram, it can be copied, resold, and reused an unlimited number of times.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters

If you reuse passwords across multiple sites, a single exposed login can unlock several of your accounts at once. Attackers automate this process through credential stuffing, feeding leaked email and password pairs into login forms across banking, email, shopping, and social media sites to see what still works. From there it is a short step to account takeover, financial fraud, or identity theft, especially if the compromised email is also your account recovery address.

How This Stealer Log Was Created

Stealer logs like this one come from malware quietly installed on someone's device, often through a fake download, cracked software, or a malicious email attachment. Once running, the malware scans the browser and saved login data, then pulls out every email, password, and site URL it can find before sending that file back to the attacker. The result is dumps like this one, packaged up and passed around on Telegram channels and dark web forums.
