Inside kur4e.txt: 99,792 Plaintext Email and Password Pairs Leaked

Behind the plain filename kur4e.txt sits a combolist of real scale. HEROIC analysts found 99,792 email and password pairs stored in plaintext inside this file, uploaded to Telegram in June 2021, each entry tied to a login URL.

What a Name Like This Signals

A short, cryptic filename like kur4e.txt is typical of files traded quickly between distributors, meant to be renamed or repackaged without drawing attention. The lack of a descriptive name does nothing to change what is inside: readable credentials ready for immediate use.

What kur4e.txt Actually Contains

• Email addresses: the account usernames paired with each password.
• Plaintext passwords: stored in readable form, usable without any cracking step.
• URLs: the login pages tied to each credential pair.

Why Nearly 100,000 Records Raises the Stakes

A file this size is efficient fuel for credential stuffing at scale, letting attackers run automated login attempts against thousands of accounts on popular platforms in a single batch. If your password was reused anywhere, you become one target among many in that run.

How a File Like kur4e.txt Comes Together

Classified as a combolist, this file was compiled from credentials gathered across multiple existing sources rather than extracted directly from one company's live systems during a breach, which is why it carries no link to a single organization.

Was Your Login Pulled Into kur4e.txt?

Scan your email to check right away. If you find a match, change that password immediately on every account where you reused it, prioritizing your email and financial logins first. This holds true whether the address is personal or tied to your workplace.
