ATM_LOGS Breach: 7,492 Passwords Leaked for Over a Year

On March 13, 2024, a Telegram user uploaded a stealer log file named "ATM_LOGS" containing 7,492 records of email addresses, plaintext passwords, and the URLs tied to each login. HEROIC analysts only flagged the file for review recently, meaning the data has likely been circulating in criminal channels for well over a year before it landed in front of a security team.

Why This Is Dangerous

That gap between the leak date and its discovery is the real problem. The longer a stealer log sits unnoticed, the more time attackers have to quietly test the credentials, sell the file to other buyers, or fold it into larger combo lists used for automated attacks.

By the time a victim hears about a leak like this, the passwords inside may have already been tried against dozens of other sites.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages

Why This Matters

Every month a leaked password goes unnoticed is another month attackers can use it. Old stealer logs still power credential stuffing attacks today, and they remain a common stepping stone toward account takeover, identity theft, and financial fraud, even years after the orignal infection.

How Stealer Logs Age Over Time

Stealer logs are created the moment malware infects a device and quietly copies saved browser passwords, autofill data, and session cookies. That single moment of infection can echo for years.

Files like ATM_LOGS often get passed between Telegram channels multiple times, repackaged and relisted under new names each time a fresh buyer wants exclusive access. This means the same 7,492 records could resurface again under a different file name down the road.

Passwords that were never changed after the original infection stay just as dangerous today as they were the day they were stolen.

Check If You Are Affected

Do not assume an old leak is no longer relevant. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like ATM_LOGS, so you can find out immediately and update any passwords that are still exposed.
