processed_20250819 Stealer Log Quietly Leaks 27,160 Logins

HEROIC analysts identified a stealer log labeled processed_20250819_062151 uploaded to a public Telegram channel on August 19, 2025. There was no announcement and no fanfare, just a file quietly added to a channel. The file exposed 27,160 compromised records from devices in the United States, including email addresses, plaintext passwords, and the URLs of the login pages the credentials belonged to.

Why This Is Dangerous

Because every password in this log was captured and stored in plaintext, there is no encryption for an attacker to break through. Each of the 27,160 records pairs a working email address with its exact password and the site it unlocks, giving anyone who quietly downloads this file everything needed to attempt a login immediately, with no warning to the people whose credentials are inside it.

What Was Exposed

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

Why This Matters

Logs like this one rarely stay contained once they surface. They circulate quietly through Telegram channels, get folded into larger combolists, and fuel credential stuffing attacks where stolen email and password pairs are automatically tested against banking sites, email providers, and social media platforms. Because these passwords were exposed in plaintext, the only real defense is whether the password was reused elsewhere, and where it was, the exposure can lead directly to account takeover, identity theft, and financial fraud.

How This Stealer Log Was Created

Logs like this one come from information-stealing malware that infects a device through a cracked application, pirated download, or malicious link. Once active, the malware quietly pulls saved usernames and passwords out of the browser, along with the exact URL of every site those credentials belong to, and compiles it all into a single file. That file is then uploaded to Telegram, where it can sit unnoticed until someone downloads it.

Check If You Are Affected

Stealer logs like this one are especially dangerous precisely because they surface quietly, with no data breach headline to alert the people affected. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out whether your information was part of this exposure before it is used against you.
