BONUS NEW ULP FRESH UP_KURZL0G NOV 13 Leaked 13,602,485 Logins

Since 15 November 2025, a combolist file uploaded to a Telegram channel under a name referencing KURZL0G has sat in circulation, exposing 13,602,485 records. HEROIC analysts confirmed each record pairs an email address with a plaintext password and a web address. Every day this file remains available online adds to the number of people who could be affected without knowing it, so scanning your email now is the only way to close that gap.

Why This Is Dangerous

The longer a file like this circulates, the more copies exist and the more attackers have had time to test the credentials inside it. Because the passwords were never hashed, there was never a delay between the leak and the moment someone could start using them.

What Was Exposed

• Email Addresses
• Plaintext Password
• URLs

At a scale exceeding thirteen million records, realistic consequences include mass automated credential stuffing, account takeovers that go unnoticed for months, and fraud carried out using accounts the real owner still believes are secure. The passage of time since the file first appeared only increases the odds that any exposed password has already been tried somewhere.

A combolist like this one is typically compiled from many separate credential leaks and infections rather than pulled from a single company's own systems, then bundled and passed around Telegram channels for anyone to use. That patchwork origin is part of why a file this large can affect people with no connection to one another beyond a reused password, unlike a stealer log tied to one continuous chain of infections.

Close the Gap Today

Scan your email to check whether it appears in this file. If it does, change that password everywhere you have reused it and enable two-factor authentication on your most important accounts.

This applies equally to personal and work email addresses caught up in the same file.
