The ‘Yahoo.com’ Combolist Put 2,292 Email and Password Pairs Online

HEROIC analysts identified a combolist labeled "Yahoo.com" uploaded to a Telegram channel on June 14, 2026. The file contains 2,292 records of Yahoo email addresses paired with plaintext passwords and the URLs where those logins were used. This is not a breach of Yahoo's own systems, it is a combolist filtered down to accounts that use a Yahoo address.

Why a Provider-Filtered Combolist Is Dangerous

Sorting stolen credentials by email provider makes them more useful to an attacker, since a Yahoo inbox can be used to reset passwords on other accounts linked to it. The passwords in this file are stored in plaintext, so anyone who downloads it can log in directly, with no cracking or guessing needed.

What Was Exposed in the Yahoo.com Combolist

• Yahoo email addresses
• Plaintext passwords
• URLs linked to the accounts

Why This Matters for Yahoo Account Holders

If one of your accounts is among these 2,292 records, an attacker can use it to run credential stuffing against banking, shopping, and social media sites where you may have reused the same password. Access to your Yahoo inbox specifically also opens the door to password resets on other services, raising the risk of account takeover, identity theft, and financial fraud.

How This Yahoo-Focused Combolist Was Built

A combolist like this one is compiled from email-and-password pairs pulled from older breaches, phishing pages, or malware infections, then sorted down to one provider, in this case Yahoo, to create a more targeted list. Files organized this way are common on Telegram because buyers often want credentials for a specific platform rather than a random mix of providers.

Check If Your Yahoo Account Was Exposed

With 2,292 Yahoo accounts already in this file, checking your exposure is worth doing without delay. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like this one, so you can find out and change any reused passwords before someone else does.
