TOR_LOG MIX 301PCS Leak: 4,880 Passwords Exposed. Check Yours.

HEROIC analysts identified a stealer log file, publicly labeled TOR_LOG MIX 301PCS, uploaded by a Telegram user on 28 June 2024. The file contains 4,880 individual records pulled directly from malware-infected devices, including email addresses, plaintext passwords, and the URLs of the sites those credentials unlock.

Why This Is Dangerous

Unlike a breach of a single company's database, a stealer log is a snapshot of what info-stealing malware quietly copied off an infected computer. That means the passwords in this file were captured at the moment they were typed or auto-filled, so they are far more likely to still be active than credentials pulled from an old corporate hack. Anyone whose device was infected had their login habits laid bare in one file, ready to be reused by whoever bought or downloaded it.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the websites and services the credentials belong to

Why This Matters

Because the passwords were stored in plaintext and paired with the exact site they unlock, attackers do not need to guess or crack anything. They can log straight into email, shopping, or financial accounts tied to these 4,880 records. If any of the affected users reused these passwords elsewhere, the risk extends to every account sharing that password, a classic setup for credential stuffing and account takeover.

How Stealer Logs Work

Stealer logs come from info-stealing malware, often hidden inside cracked software, fake installers, or phishing attachments. Once installed, the malware silently harvests saved browser passwords, autofill data, and session cookies, then sends everything back to the attacker. Criminals bundle these harvested records into packages like this 301-piece mix and trade or sell them on Telegram channels and dark web marketplaces, often for a fraction of what the data is worth to the people who bought it.
