1,528,207 Passwords From lines_twitch Just Surfaced Online

In the lines_twitch file, HEROIC analysts found 1,528,207 email addresses sitting directly next to the plaintext passwords and web addresses they unlock, dated January 2026. That pairing, login and destination together, is what turns a list of credentials into a working set of accounts an attacker can walk straight into. The only way to know if you're affected is to scan your email.

At Over a Million Records, Scale Is the Danger

A file this large does not need to be sophisticated to cause damage, it only needs volume. With over 1.5 million entries, even a small percentage of successful logins adds up to a very large number of compromised accounts.

What a File of Over 1.5 Million Records Holds

• Email Addresses: gives an attacker a direct line to contact or impersonate the account owner.
• Plaintext Password: stored and leaked in fully readable form, so no cracking is needed before it can be used to log in.
• URLs: shows exactly which site or service each password belongs to, turning a guess into a targeted login attempt.

1,528,207 Logins in a Single File

At this scale, automated tools can work through the entire file in bulk, flagging every pair that still logs in. Even a tiny success rate still means tens of thousands of working accounts.

How a Combolist Reaches Millions of Records

Lists this large are typically assembled by merging many smaller leaks and logs together over time, then testing the combined set against live login pages to confirm which pairs still work.

Is Your Login Among 1.5 Million Records?

Start by taking a moment to scan your email and see whether this file, or any other, included your address. If it did, change that password on every account where you have reused it, and use a unique password for every account going forward. This applies whether the address involved is a personal inbox or a work email, since either one can open the door to the other.
