The ‘306K Gmail Combolist’ Quietly Leaked 292,804 Real Passwords

HEROIC analysts identified a combolist labeled "306K GMAIL Combolist 05-22" uploaded to a Telegram channel on May 23, 2026. Despite the "306K" in its name, the verified file contains 292,804 records of Gmail email addresses paired with plaintext passwords and the URLs where those logins were used.

Why a Gmail-Specific Combolist Raises the Stakes

Targeting one email provider means every record in this file is tied to a Gmail account, which often serves as the master key to someone's entire online life through password resets, connected apps, and saved payment details. The passwords are stored in plaintext, so anyone with the file can log in directly, with no cracking required.

What Was Exposed in the Gmail Combolist

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

Why This Matters for Gmail Users

If an attacker gets into a Gmail inbox, they can often reset the password on every other account linked to that address, from banking to shopping to social media. For the 292,804 accounts in this file, a reused or exposed Gmail password can quickly turn into full account takeover, identity theft, or financial fraud across multiple services at once.

How a Gmail-Focused Combolist Gets Built

A combolist like this one is assembled by pulling email-and-password pairs from older breaches, phishing pages, or malware infections and then filtering the results down to one provider, in this case Gmail, to create a more targeted and valuable file. Combolists sorted by provider are common on Telegram because buyers often want credentials for a specific platform rather than a random mix.

Check If Your Gmail Was Exposed

With 292,804 Gmail accounts already in this file, checking your exposure is worth doing right away, given how much access a compromised Gmail account can provide. 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 they are used.
