The Logs_30 May Stealer Leak Exposed 14,112 US Passwords

HEROIC analysts identified a stealer log dump titled "Logs_30 May" that a Telegram user uploaded on May 30, 2025. The file contained 14,112 records tied to United States based accounts, including email addresses, plaintext passwords, and the URLs of the login pages those credentials belonged to.

Why This Is Dangerous

The most serious detail in this leak is that the passwords were stored and exposed in plaintext, meaning there is no encryption standing between an attacker and a working login. Paired with the URL for each account, anyone who downloads this file can immediately see which site a credential unlocks and attempt to log in with it. Stealer logs like this one are traded and re-shared quickly once they hit public Telegram channels, so the exposure window for affected users starts the moment the file goes up.

What Was Exposed in the Logs_30 May Leak

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

Why This Matters for the 14,112 Affected Accounts

When an email, password, and login URL travel together, an attacker has everything needed to attempt account takeover with no guessing involved. If any of the 14,112 people in this file reused their password elsewhere, the same combination can be tested against banking, email, and shopping sites in a matter of minutes through automated credential stuffing tools. From there, the path runs directly to identity theft and financial fraud, since a compromised email account is often the key to resetting passwords on everything else tied to it.

How Stealer Logs Like This One Are Created

A stealer log is the output of malware that infects a device and quietly harvests whatever login data it can find, usually credentials saved in a browser, autofill data, and session information. Once collected, the malware sends this information back to the attacker, who packages it into a file like the one uploaded here. These files are then dropped into Telegram channels or dark web forums, sometimes for free to build a reputation, sometimes sold outright. Because the theft happens on the victim's own device rather than through a breach of a company's servers, stealer logs can expose credentials for dozens of unrelated sites all in a single file.

Check If You Are Affected

If you are based in the United States, or think you may have had credentials swept up in a stealer log campaign around late May 2025, it is worth checking now rather than waiting. HEROIC's free breach scanner searches against a database of more than 400 billion leaked records, including stealer log dumps like this one, to tell you whether your email address has surfaced in a known breach. If it has, changing the affected password immediately, and any other account where you reused it, is the fastest way to close the door an attacker would otherwise walk through.
