Your Gmail Login May Be Compromised: 19,736 Records in 19786 Leak

What HEROIC Analysts Found in the 19786 Gmail Combolist Leak

In July 2026, HEROIC analysts identified a large combolist titled "19786 MIXED Gmail COMBOS GOOD FOR EVERY SITEC," uploaded to a Telegram channel by an anonymous user. The file contained 19,736 records of email addresses paired with plaintext passwords and the URLs those credentials were used on, with a focus on Gmail accounts.

Why This Is Dangerous

The file's own name claims the credentials work "for every site," a common marketing line among combolist sellers that signals the compiler believes these Gmail logins can be reused to break into accounts well beyond email. Paired with plaintext passwords, that makes this a high-value target for automated attacks.

What Was Exposed in the 19786 Gmail Combolist

• Email addresses (Gmail-focused)
• Plaintext passwords
• URLs of the associated websites

Why This Matters for the 19,736 Affected Accounts

Nearly 20,000 records is a substantial volume for a credential stuffing campaign. Because Gmail accounts often double as recovery email for banking, shopping, and social media logins, anyone among the 19,736 affected accounts who reused their password faces significant risk of account takeover, identity theft, or financial fraud.

How a "Mixed" Gmail Combolist Gets Built

Compilers gather Gmail-tied credentials from older breaches and stealer malware logs, mix them into a single file, and market it as broadly usable across many sites to attract buyers or downloaders. The scale and marketing language in this file's name are typical of combolists sold or shared through Telegram.
