AU Stealer Log Leak: 1 Record Exposed, Check Your Email Now

HEROIC analysts identified a stealer log dump labeled "AU," uploaded to a Telegram channel on 18-Jun-2026. The file contained a single record, made up of an email address, a plaintext password, and the URL of the site that login belonged to.

Why Even a One-Record Stealer Log Leak Is Dangerous

The size of this leak is small, but the risk to the one person affected is not. Whoever holds this file has a working email address, its plaintext password, and the exact website it unlocks, which is everything needed to log straight into that account without any guessing.

What Was Exposed

• Email address
• Plaintext password
• URL of the website tied to the login

Why This Matters

Because the password is unencrypted and matched to a specific site, this single credential is ready for immediate account takeover if it is still valid. If that password was reused on other accounts, such as email, banking, or shopping, the same credential stuffing risk applies there too.

How Stealer Logs Work

Stealer log malware infects a device, often through a fake download or malicious attachment, and quietly records saved passwords, autofill data, and browser session details as they are typed. The results, sometimes just a handful of entries, are compiled into a log file and sold or shared on Telegram channels and dark web forums.

Check If You Are Affected

Even one exposed credential is worth checking on. Use HEROIC's free breach scanner to see if your email address appears in this or any other leak. It searches a database of more than 400 billion breached and leaked records to show you instantly if your information has been exposed.
