1,305 Records Exposed in TOR_LOG MIX 299PCS Stealer Log Breach

HEROIC discovered 1,305 records exposed in the TOR_LOG MIX 299PCS stealer log breach on October 15, 2024. The 299PCS archive was posted alongside its sibling 301PCS drop by the same Telegram operator, packaging a distinct pool of victim machines under a slightly smaller bundle count to broaden the catalog.

Why This Stealer Log Is Dangerous

Unlike company database leaks, this archive puts raw end-user authentication material directly into attacker hands. Every line is a ready-to-use login that can be sprayed against banks, email, streaming services, and corporate portals. Because the data was captured from browsers, the passwords reflect what users actually type, not hashed representations.

What Was Exposed in TOR_LOG MIX 299PCS

• Email addresses used across personal and work identities
• Plaintext passwords pulled from saved browser vaults
• URLs showing exactly which services the credential unlocks
• API host references for connected mobile and desktop apps
• Endpoint metadata identifying the compromised machine

The small record count hides outsized risk because each line is a full credential set, not a single field.

Why This Matters

Attackers target mid-size log drops like 299PCS precisely because they are fresh enough to outrun password rotation and small enough to test manually. Corporate security teams rarely see individual stealer infections in SIEM alerts, so the first sign of compromise is often an inbound login attempt from the leaked credential. Reused passwords turn one infected home PC into a full enterprise breach.

How a Stealer Log Like TOR_LOG MIX 299PCS Works

The attack chain starts with a malicious installer, typically disguised as cracked software or a game cheat. Once executed, infostealers like Lumma or StealC iterate through browser profile folders, decrypt saved credentials, scrape cookies, and dump everything into a .zip. The operator forwards the archive to a Telegram drop channel where it is rebundled into lots like 299PCS for buyers and freeloaders.
