ATM_LOGS Breach: 4,411 Passwords Exposed on Dark Web

HEROIC analysts discovered a stealer log file named ATM_LOGS uploaded to Telegram in February 2024. Despite the name, this is not a breach of physical ATM machines, it is a batch of 4,411 records harvested from malware-infected computers, containing email addresses, plaintext passwords, and the URLs each login belongs to.

What Is a Stealer Log, Exactly

A stealer log is essentially a snapshot of everything saved in a victim's web browser at the moment they got infected. Think of it as a leaked notebook where every password you ever told your browser to remember is written down in plain sight, right next to the site it unlocks.

This is different from a traditional company data breach, where a hacker breaks into one organization's servers. Here, the malware sits on the individual person's device and quietly copies data over time, then ships it off in a single file, exactly like the one flagged in this report.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs tied to each login

Why This Matters

Because the passwords are plaintext and matched directly to specific websites, this is about as ready-to-use as stolen data gets. Attackers can immediately attempt credential stuffing, plugging these exact logins into email providers, banks, and shopping sites to see where else they work.

If even one of these 4,411 victims reused a password, that single mistake can casacade into full account takeover, identity theft, or direct financial fraud within minutes of the log being downloaded.

How Stealer Log Malware Actually Works

Stealer malware usually sneaks onto a device disguised as cracked software, a fake update, or a malicious attachment. Once active, it scans the browser's saved password vault, autofill fields, and session cookies, then bundles everything it finds into a text file like the one behind this report.

That file is then uploaded to a Telegram channel or dark web marketplace, where other criminals download it for free or pay a small fee to access fresh, unused credentials. The whole process, from infection to sale, can happen in a matter of days.

Check If You Are Affected

Stealer logs like ATM_LOGS surface constantly, and most victims never even know their browser was quietly compromised. HEROIC's free breach scanner checks your email against a database of over 400 billion compromised records to see if you show up in leaks like this one.
