The Dialog1.net.pl Stealer Log Leaked 14,942 Emails and Passwords

HEROIC analysts identified a stealer log dataset tied to dialog1.net.pl that surfaced on Telegram on 10-Jun-2026. The file was uploaded directly by a Telegram user rather than a formal breach announcement, which is typical of how stealer log data circulates today. In total, the log contains 14,942 records, including email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This Is Dangerous

Stealer logs are different from a typical database leak. Instead of coming from a single hacked company, this data was harvested directly from infected computers, capturing whatever usernames and passwords were saved or typed into a browser at the time of infection. Because the log pairs each password with the exact URL it was used on, an attacker does not have to guess which site a credential belongs to. They can plug the email, password, and URL straight into a login page and attempt to get in immediately.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Because these passwords were stored in plaintext, anyone who obtains this file can use them without needing to crack or decrypt anything. If any of these 14,942 people reused a password across multiple accounts, which is extremely common, attackers can attempt credential stuffing against email providers, banking sites, and social media accounts. A successful login can lead to account takeover, identity theft, or direct financial fraud if payment information is reachable from the compromised account.

How Stealer Log Leaks Work

A stealer log is generated by malware that infects a victim's device, often through a fake download, cracked software, or a malicious email attachment. Once installed, the malware quietly collects saved browser passwords, autofill data, and session information, then sends it back to the attacker. That data is later packaged into a log file and sold or shared, sometimes for free, on Telegram channels and dark web forums. Unlike an old database dump, stealer logs are often fresh, meaning the passwords inside are more likely to still be active.

Check If You Are Affected

If you have ever entered a password into a site tied to dialog1.net.pl, or you tend to reuse passwords across accounts, it is worth checking now rather than waiting. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer log data like this, to tell you whether your email address has been exposed. Run a free scan and change any reused passwords immediately if you find a match.
