ATM_LOGS Stealer Leak Exposed 3,859 Plaintext Passwords

HEROIC analysts identified a stealer log uploaded to a Telegram channel on 26 June 2024 under the label "ATM_LOGS." The dump exposed 3,859 records tied primarily to United States users, including email addresses, plaintext passwords, and the URLs of the accounts these credentials unlock.

Why the ATM_LOGS Leak Is Dangerous

A name like ATM_LOGS points to credentials tied to banking or financial platforms, exactly the kind of accounts where a compromised login has direct money at stake. Because the passwords in this file sit in plain, readable text next to the exact URL each one belongs to, an attacker can open the matching site and log straight into the account, with nothing standing in the way.

What Was Exposed in This Leak

• Email Addresses: the usernames tied to each set of stolen credentials
• Plaintext Passwords: readable exactly as typed, with no encryption slowing down misuse
• URLs: the specific login pages each credential pair was captured from

Why This Matters

Financial account logins are among the most valuable targets for attackers, since a working password can lead directly to fraudulent transfers, drained balances, or new accounts opened in the victim's name. Because so many people reuse the same password across banking, email, and shopping sites, a single credential from ATM_LOGS can also power credential stuffing attacks against unrelated accounts, opening the door to broader account takeover and identity theft.

How Stealer Logs Work

A stealer log is the product of infostealer malware, software that quietly infects a device and copies saved passwords, autofill data, and login URLs straight out of the victim's browser. The stolen information is bundled into a single file and either sold on criminal marketplaces or uploaded for free to Telegram channels, as happened with ATM_LOGS. Because the data is pulled directly from the browser, it is typically accurate and current at the time the malware ran.

Check If You Are Affected

If you handle banking or financial accounts online, checking your exposure is worth the thirty seconds it takes. HEROIC's free breach scanner checks your email address against a database of more than 400 billion leaked records, giving you a clear answer and next steps for locking down any account that shows up.
