What Is a Stealer Log? 92_Boss Leak Exposes 4,989 Records

4,989 Records Leaked in the 92_Boss Stealer Log

HEROIC analysts uncovered a stealer log file called 92_Boss, uploaded by a Telegram user on 26 April 2024. The file contained 4,989 records taken from malware-infected computers, including email addresses, plaintext passwords, and the URLs of the accounts those passwords unlock.

Why the 92_Boss Leak Is Dangerous

What sets this leak apart is how little effort it takes to abuse. The passwords were captured and stored in plaintext, so nothing needs to be decrypted or cracked. Someone browsing this file can see an email address, its password, and the exact site it was used on, all in one line. That's enough for an attacker to attempt a login within seconds, with no guesswork involved.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were captured from

Why This Matters

If your email and password show up in the 92_Boss file, the biggest risks are credential stuffing and account takeover. Because the leak pairs each login with the exact URL it came from, attackers can skip the trial and error and go straight to testing your credentials on the real site. Reused passwords make this worse, since one exposed login can open the door to several of your other accounts.

How Stealer Logs Work

A stealer log is the output of malware built to quietly steal information from an infected device. It typically arrives disguised as a game cheat, cracked software, or a fake installer, and once it runs, it pulls saved passwords, autofill entries, and browsing details straight out of the browser. Everything it collects is packaged into a single file, like this one, and then passed around or sold on Telegram and dark web forums.

Check If You Are Affected

Stealer logs like 92_Boss circulate quietly until someone puts the stolen credentials to use, so it pays to check early. HEROIC's free breach scanner compares your email against a database of more than 400 billion leaked records, so you can find out immediately if your information was part of this leak and change any exposed passwords right away.
