What Is a Combolist? Dark Combo Leak Exposes 163,910 Logins

Inside the "Dark Combo Good Hit" Leak

HEROIC analysts tracked a combolist titled "Dark combo good hit" uploaded to Telegram on August 8, 2026. The file contains 163,910 records, each combining an email address, a plaintext password, and the URL of the service the credentials unlock.

Why the Dark Combo Leak Is Dangerous

The phrase "good hit" in the file's title is criminal slang for credentials that have already been tested and confirmed to work. That label means the person distributing this file has verified at least a portion of the 163,910 records, which makes them more immediately useful to an attacker than an unverified list of the same size.

What Was Exposed

• Email addresses belonging to real account holders.
• Plaintext passwords with no encryption protecting them.
• URLs showing exactly which website or app each login was taken from.

Why This Matters

With over 163,000 records and a claim of verified "hits," this file is well suited to large-scale credential stuffing attacks. Automated tools can run each email and password pair against major websites within minutes, and because so many people reuse passwords, a single successful login on one site often opens the door to email, banking, or shopping accounts elsewhere.

How Combolists Work

A combolist is created by gathering leaked credentials from multiple sources, older breaches, stealer logs, and phishing campaigns, then formatting them into simple email-and-password pairs. Criminals often test a sample of the list against popular sites first, then advertise the file as containing confirmed "good hits" to increase its resale value or attract more downloads.

Check If You Are Affected

Given the scale of this leak, it's worth checking your own exposure now. HEROIC's free breach scanner searches more than 400 billion compromised records, including this combolist, so you can find out in seconds and change any password that's been exposed.
