HEROIC Analysts Find 16,552 polka.co.za Passwords on Telegram

HEROIC analysts discovered a stealer log tied to polka.co.za while monitoring Telegram in June 2026, where a threat actor had uploaded the file. Inside were 16,552 records made up of email addresses, plaintext passwords, and the URLs those credentials were used on.

Why This polka.co.za Stealer Log Is Dangerous

Analysts flagged this log as highly usable the moment it was found. The passwords are stored in plaintext and lined up directly with the exact web address each one opens, so an attacker does not need to crack or decode anything before trying to log in with the stolen credentials.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

Because each password is matched to its exact login page, attackers can move straight to account takeover across the 16,552 accounts in this log. If any of these passwords were reused on other sites, such as email, banking, or shopping accounts, credential stuffing tools let attackers test the same password across many unrelated services, spreading the damage well beyond this one leak.

How Stealer Logs Work

Stealer logs come from malware that infects a device and quietly copies saved browser passwords, autofill entries, and the web addresses tied to them, then sends everything back to the attacker. Because the theft happens on the victim's own computer rather than a hacked company server, analysts often find these credentials still active when the logs surface on Telegram.
