How TOR_LOG MIX 371PCS Leaked 5,175 Passwords to the Dark Web

On February 29, 2024, a Telegram user posted a stealer log collection called TOR_LOG MIX 371PCS, bundling together data pulled from 371 seperate infected machines. HEROIC analysts reviewed the file and confirmed 5,175 records, each one containing an email address, a plaintext password, and the URL of the site the credential belonged to.

Why the TOR_LOG MIX 371PCS Leak Is Dangerous

This is not a case of a single company losing customer data. It's a mashup of logins harvested from real people's browsers, one machine at a time, then packaged together for anyone to download. Because the passwords sit right next to the sites they unlock, a criminal can log in immediately without any extra work.

There is also no password hashing to slow anyone down. Every credential in the file is readable plaintext, ready to be copied straight into a login form.

What Was Exposed in This Leak

• Email Addresses
• Plaintext Passwords
• Login URLs for each account

Why This Matters

A password recycled across several accounts turns one small leak into a much bigger problem. Attackers automate credential stuffing, feeding leaked email and password pairs into bots that hammer login pages across the internet.

Any account that accepts one of these logins can be taken over. That opens the door to identity theft, fraudulent purchases, and drained bank or crypto accounts, all stemming from a single reused password.

How This Stealer Log Breach Happened

Stealer logs like this one begin with malware, not a hack of a website's servers. Someone downloads a cracked program, a fake game cheat, or opens an infected attachment, and the malicious code installs itself quietly in the background.

From there, the malware digs through the browser's stored passwords, cookies, and autofill fields, then sends everything it finds back to whoever is running the operation. The 371 machines behind TOR_LOG MIX 371PCS were each infected this way, and the results were later merged into one combined file and dumped on Telegram for anyone to grab, free of charge.

Check If You Are Affected by the TOR_LOG MIX 371PCS Leak
