23,132 Plaintext Logins Listed in 23K MIXED MAIL COMBOLIST

HEROIC analysts logged the 23K MIXED MAIL COMBOLIST, dated February 6, 2026. The file lists 23,132 email and plaintext password pairs with URLs. The 23K in the label is part of the name only, and the count taken from the record is 23,132.

Label Words and Record Facts

People who share a file pick its name, so the words MIXED and MAIL describe nothing the record confirms. They do not show which services are involved or where any pair originated. The stored facts are simpler: the type is a combolist, the passwords are plaintext, and the three kinds of data are email addresses, passwords and URLs.

The Data in Each Entry

• Email addresses, the login names and the destination for reset messages.
• Plaintext passwords, written in full with no scrambling.
• URLs, the sites the pairs are associated with.

Reuse Turns One Entry Into a Chain

An entry matters when its password protects more than one login. Tried on another site, the pair can open it, and an inbox opened that way can reset the passwords of other services. The result is a chain of logins that all fall because one password was reused. Distinct passwords keep each login separate.

How Combolists Come Together

A combolist is made by collecting pairs of email addresses and passwords from different places and saving them in one file. People test the pairs against other sites because passwords get reused across sites. Once pairs are merged, the details of their origin are gone, so the file itself does not identify whose systems they came from.

Finding Out Where You Stand

The answer comes from a lookup: scan your email to see your information. If your address is listed, change that password on every site where you used it and choose a different password for each, starting with email and banking. Whether the address is for work or for home, the check is the same.
