TOR_LOG MIX 371PCS Breach: Attackers Can Steal 5,284 Passwords

HEROIC analysts identified a stealer log dump known as TOR_LOG MIX 371PCS, uploaded to a Telegram channel in February 2024. The file contained 5,284 individual records, each one pulled directly from an infected computer. Every record includes an email address, a saved website URL, and the plaintext password tied to that login.

Why This Stealer Log Is Dangerous

Unlike a typical password breach, this data did not come from a hacked company database. It came from malware sitting quietly on someone's own device, copying whatever was saved in their browser. That means the passwords in this file are almost certainly still in use, and they are stored in plain, readable text with no encryption to slow an attacker down.

Anyone who recieves a copy of this file can log straight into the affected accounts. There is no password to crack and no hash to decode. The username, the site, and the password are all sitting right next to each other.

What Was Exposed

• Email addresses
• Plaintext passwords
• Saved website URLs (login pages tied to each credential)

Why This Matters for Your Other Accounts

Most people reuse the same password across several sites. When a credential like this leaks, it becomes fuel for credential stuffing attacks, where criminals plug the same email and password into dozens of other platforms to see what opens. That single reused password can quickly turn into a full account takeover, identity theft, or financial fraud if it unlocks a banking or shopping account.

Because the passwords here are plaintext and paired with the exact URL they belong to, attackers do not even need to guess where to try them. The file hands them a ready made target list.

How Stealer Log Breaches Happen

A stealer log is the output of infostealer malware, a type of program that infects a device through a fake download, a cracked piece of software, or a malicious email attachment. Once installed, it quitely searches the browser's saved password manager, cookies, and autofill data, then packages everything into a single file.

That file is often sold or given away for free on Telegram channels and dark web forums, exactly how TOR_LOG MIX 371PCS ended up in circulation. Because the malware runs on the victim's own machine, it can capture logins the moment they are typed, seperate from any protection the website itself might have in place.
