Inside a Stealer Log File Holding 16 Saved Account Logins

The file itself is a stealer log, one of thousands of raw malware exports that circulate on Telegram with little more than a machine ID for a name. HEROIC analysts opened this one, dated June 9, 2020, and found 16 saved account logins inside, each with a plaintext password and the URL it opens.

Why This Is Dangerous

A file like this carries no branding and no company name because it was never collected from one company's systems in the first place. It is a direct export of whatever a piece of malware found saved in a browser, which means every password inside was, at some point, actively in use.

What Was Exposed

• Email addresses: the login identifier tied to each of the 16 saved accounts.
• Plaintext passwords: pulled live from browser storage, readable and usable right now.
• URLs: the exact login page each saved credential pair belongs to.

Why This Matters

Files like this rarely stay in one place. Once a stealer log is posted to a Telegram channel, it gets copied and folded into larger collections, meaning the 16 accounts here can end up cross-referenced against other leaks long after the original post is gone.

How This Breach Type Works

A stealer log is generated by malware running on an infected device, not by a breach of any online service. The malware reads saved passwords and autofill data straight out of the browser and sends the results back to whoever controls it, who then shares or sells the file.

Is One Of These 16 Logins Yours?

Scan your email to check it against this file and HEROIC's full breach index. A match means the device that leaked this data may still be compromised.

Run a malware scan on any device where you let the browser save your passwords, then reset every credential it had stored.

Check your work email as well as personal accounts, since stealer logs save whatever was logged into, without sorting by purpose.
