Dark Web Intel: “79_Boss” Log Leaks 3,870 Passwords Online

Dark Web Intel: The "79_Boss" Stealer Log

As part of routine dark web monitoring, HEROIC analysts uncovered a stealer log named "79_Boss," tied to a Telegram upload and dated 26-Apr-2024. The file contains 3,870 records made up of email addresses, plaintext passwords, and the URLs those credentials were captured from.

Why This Dark Web Find Is Dangerous

Stealer logs like this one circulate quietly in Telegram groups and dark web marketplaces long before most victims ever find out their information was taken. Because the passwords in this file are stored in plaintext and matched to specific site URLs, anyone who gets their hands on the file can log directly into the accounts listed, without cracking a single password.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the exact site each login belongs to

Why This Matters

Everyone in this log faces an immediate account takeover risk, since the exposed password works as-is on the linked site. The risk does not stop there either, since anyone who reused this password on other accounts is exposed to credential stuffing on services that were never part of this specific leak.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies whatever the browser has saved, including passwords, autofill entries, and site URLs. That stolen data gets bundled into a file and passed to the attacker, who often shares or sells it in dark web forums and Telegram channels, exactly where HEROIC analysts found the "79_Boss" file during ongoing monitoring.

Check If You Are Affected

Dark web data like this can sit unnoticed for a long time before it resurfaces, so it is worth checking your exposure now. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, and tells you right away if you were affected.
