ATM_LOGS Leak: What Attackers Can Do With 4,435 Stolen Logins

ATM_LOGS: What HEROIC Analysts Found

On 08-Feb-2024, HEROIC analysts uncovered a stealer log file named ATM_LOGS, uploaded to a Telegram channel by an anonymous user. The file held 4,435 records, each combining an email address, a plaintext password, and the URL of the site the login belongs to, all lifted from malware-infected devices.

What Attackers Can Do With the ATM_LOGS Data

With plaintext passwords in hand, an attacker doesn't need to crack, guess, or brute-force anything. They can simply copy each email and password pair from ATM_LOGS and attempt to log directly into the matching website. If that password has been reused anywhere else, the same attacker can pivot into email inboxes, banking apps, or social media accounts within minutes.

What Was Exposed in the ATM_LOGS File

• Email addresses
• Plaintext passwords
• URLs showing which site each login unlocks

Why This Matters Beyond a Single Password

Password reuse turns one leaked login into many. Criminals feed stolen email and password combinations like these into automated credential stuffing tools that test them across hundreds of popular websites at once. Every successful login is a potential account takeover, and every account takeover is a step closer to identity theft or financial fraud.

How Stealer Logs Like ATM_LOGS Are Built

A stealer log is created when malware secretly installed on a victim's device collects saved browser passwords, autofill entries, and active login sessions, then bundles it all into a single file. That file, in this case labeled ATM_LOGS, is then sold or shared in criminal Telegram channels, often within days of the original infection.
