Someone Has Your Password: 8,667 Logins in 8.7K MIX Leak

HEROIC analysts discovered a mixed credential dump titled "8.7K MIX" circulating on Telegram in May 2026. The stealer log file contained 8,667 compromised records drawn from multiple services and platforms. Each entry includes an email address, a plaintext password, and a URL linking the credential to a specific login page. The mixed nature of this dump means victims span a wide range of websites and industries, amplifying the potential for widespread account compromise.

Why Plaintext Passwords Leave You Completely Exposed

Passwords stored or leaked in plaintext offer zero resistance to attackers. There is no hash to crack, no encryption to break. The moment a threat actor downloads this file, every credential inside is ready to use against live accounts.

Mixed dumps like 8.7K MIX are particularly dangerous because they aggregate credentials from many different sources. An attacker with this file can attempt logins across email providers, social media platforms, online shopping sites, and financial services simultaneously.

If you use the same password across multiple sites, a single entry in this dump could give an attacker access to your entire digital life. The plaintext format eliminates the time barrier that hashed passwords would otherwise provide.

What Was Exposed in the 8.7K MIX Dump

• Email Addresses — Personal and business email addresses from various providers and domains
• Plaintext Passwords — Fully readable passwords with no encryption or hashing applied
• URLs — Specific login pages and services where each credential was captured

Why 8,667 Mixed Credentials Fuel Large-Scale Attacks

Mixed credential dumps are prized by cybercriminals because they provide a diverse set of targets. Automated credential stuffing tools can ingest all 8,667 entries and test them against popular services at high speed, exploiting the fact that most people reuse passwords across accounts.

The URLs included in each record tell attackers exactly which service the password belongs to, but the real danger lies in testing those same credentials elsewhere. A password captured from a streaming service login often works on the victim's email, banking, or cloud storage accounts.

These mixed dumps are also commonly combined with other leaked datasets to build comprehensive credential databases that power ongoing attack campaigns over weeks and months.

How Stealer Logs Quietly Siphon Your Credentials

Stealer log files are the output of infostealer malware infections. Programs like RedLine, Vidar, and Raccoon Stealer run silently on infected devices, extracting saved passwords from web browsers, email clients, FTP applications, and cryptocurrency wallets.

The malware typically arrives through phishing emails with malicious attachments, fake software cracks, or compromised websites that deliver drive-by downloads. Once active, it operates invisibly, sending harvested data to attacker servers without triggering antivirus alerts in many cases.

Because the malware captures credentials as the user types or retrieves them from browser password stores, the resulting stealer logs contain credentials in plaintext regardless of how securely the original service stores passwords on its servers.

Check If Your Credentials Were Exposed

With 8,667 records spanning multiple platforms, the 8.7K MIX dump could contain credentials from virtually any online service. If you have ever saved a password in your browser or logged into a website from a device that may have been compromised, your credentials could be in this file.

Use the HEROIC data breach scanner to search across more than 400 billion compromised records. Enter your email address to find out whether your credentials appeared in this dump or any of the thousands of other breaches in the HEROIC database, and take immediate steps to change affected passwords.
