Check Your Email: 63.799 Lines Mix Exposed 59,911 Logins

HEROIC analysts reviewed a file named 63.799 Lines Mix, dated 20 Jan 2026, and counted 59,911 working records that pair an email address with a plaintext password and the site it unlocks. With that many logins already out, scanning your email is the only way to confirm whether you are one of the 59,911 exposed.

What a file this size is actually used for

A list of nearly sixty thousand logins is built for speed, not for careful review. Tools designed for bulk credential testing can run through the entire file in a short run, surfacing every account that still accepts a leaked password.

What the 63.799 Lines Mix File Contained

• Email Addresses confirms each account is active, strengthening any phishing attempt built around it.
• Plaintext Password is stored as plain text, so each entry functions as a working login right away.
• URLs identify the exact site every password was meant for, cutting out any guesswork.

Real-world consequences

A reused password surfaces the same risk on every account built on it, well beyond the one this file is tied to. Access to a working email login can also let an attacker approve password changes on linked services, spreading one exposed row into several.

How a mixed file like this is assembled

A combolist like this is built by pairing email addresses with passwords pulled from earlier leaks and reused-password lists, then checked against live login pages. Whoever assembles the file is not breaking into any one company, they are testing whether people typed the same password somewhere else. A working pair becomes an open door into whatever account that password still unlocks.

See if your login is in this file

Scan your email to check it against the 63.799 Lines Mix file and other leaks HEROIC tracks. If there is a match, change that password now and stop reusing it elsewhere.

Check work email addresses in addition to personal ones, since both show up in files of this size.
