The 1500 Mix Valid Exposed 1,538 Stolen Accounts on the Dark Web

HEROIC analysts identified this stealer log on June 21, 2026. The breach exposed 1,538 records, with stolen data including email addresses, plaintext passwords, and URLs. The source is identified as 1500 mix valid uploaded by a Telegram User.

Why This Is Dangerous

This stealer log contains plaintext passwords paired directly with email addresses and the websites where those credentials were used. Because the passwords are stored in readable text rather than encrypted form, attackers can begin using them immediately without any additional processing. When someone's email and password are exposed together, every account using that same password is at risk.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

With 1,538 stolen email and password pairs now circulating on the dark web, affected individuals face risks including credential stuffing attacks, unauthorized account takeover, identity theft, and financial fraud. Cybercriminals use automated tools to test stolen credentials across dozens of websites within minutes of acquiring them.

How a Stealer Log Works

A stealer log is created by malware that is installed on a victim's device, often without their knowledge. The malware silently records login credentials as the user types them and captures session cookies from open browser tabs. It then packages that information into files that are sold or shared in private Telegram channels and dark web forums.
