The TOR_LOG MIX Breach Explained: 5,079 Stealer Records Exposed

What Happened

On October 24, 2024, a Telegram user posted a stealer log pack labeled TOR_LOG MIX 301PCS to a public credential-sharing channel. The MIX tag signals that the file is a combined dump pulled from multiple infostealer campaigns rather than a single botnet, which is why it spans a wide variety of regions, browsers, and target services. Dark web monitors picked up the upload within hours, preserving the full archive before the original post could be deleted.

Scope of the Exposure

The TOR_LOG MIX archive unpacked into 5,079 individual records, each tied to a separate infected device. Records follow the classic stealer log format: a login URL, the account email or username, and a plaintext password harvested directly from the browser or desktop client. API host entries are also present, meaning the data goes beyond consumer services and touches developer and cloud platforms as well.

Types of Data Exposed

• Email addresses used to log in to online accounts
• Plaintext passwords captured from infected browsers
• Login URLs and API host strings pointing to each target service
• Indicators that the source endpoint was infected with infostealer malware

Why TOR_LOG MIX 301PCS Is Dangerous

Mixed stealer packs are especially risky because they bundle credentials from unrelated victims into a single, easy-to-query file. Attackers feed TOR_LOG style datasets into credential-stuffing tools, session replay scripts, and targeted phishing workflows. With URLs attached to each record, there is no reconnaissance needed: the exact target service is already paired with a working username and password.

How to Check Your Exposure

The HEROIC Data Breach Engine ingests Telegram stealer drops like TOR_LOG MIX 301PCS. A quick lookup against your primary email shows whether any of the 5,079 records in this drop match your identity and whether the same email appears in other stealer logs from the same period.

What to Do If You Are Affected

• Treat any device tied to a matching credential as infected and run a full malware scan.
• Rotate passwords for every account stored in the affected browser, prioritizing email and finance.
• Turn on multi-factor authentication wherever it is available.
• Invalidate saved sessions and revoke OAuth tokens and browser cookies.
• Enable HEROIC monitoring to receive alerts on future TOR_LOG or infostealer drops that reference your data.
