One Telegram Post. 5,977 Passwords. Zelenka Cloud Free Logs.

HEROIC analysts found a stealer log titled "ZELENKA CLOUD FREE LOGS" that a Telegram user uploaded on January 7, 2024. One Telegram post, one file, 5,977 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 word "free" in the file's name is the detail that matters most here. Logs labeled this way are often posted to build a reputation on a forum or channel before an operator starts charging for fresher batches, which means this file was likely handed out widely with no barrier to access. The passwords inside are stored in plaintext, so there is no encryption standing between an attacker and a working login, and the matching URL for each account tells an attacker exactly where to try it.

What Was Exposed in the Zelenka Cloud Free Logs Leak

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

Why This Matters for the 5,977 Affected Accounts

An email, password, and login URL bundled together gives an attacker everything needed to attempt account takeover with no guesswork. If anyone among these 5,977 accounts reused their password elsewhere, the same combination can be tested against banking, email, and shopping sites within minutes through automated credential stuffing tools. From there, the risk extends into identity theft and financial fraud, since a compromised email account is often the key to resetting passwords on everything else tied to it.

How a "Free Logs" Stealer Dump Gets Made and Shared

A stealer log is the output of malware that infects a device and quietly harvests whatever login data it can find, typically credentials saved in a browser, autofill entries, and active session data. The infected machine sends this haul back to the attacker, who compiles it into a file and posts it publicly, sometimes for free, to build a name for themselves before selling access to fresher logs later. Because the theft happens on the victim's own device rather than through a breach of a company's servers, a single stealer log can expose credentials for dozens of unrelated sites at once.

Check If You Are Affected

If you are based in the United States, or think your credentials could have been swept up in a stealer log campaign, checking your exposure now is worth doing even if this particular leak dates back to early 2024. HEROIC's free breach scanner searches 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, change the affected password immediately, along with any other account where you reused it.
