RO Combolist Leak: Search Your Email for These 8,166 Records

RO Combolist Leak: 8,166 Email and Password Records Exposed

On 14-Jun-2026, HEROIC analysts identified a combolist labeled "RO" uploaded by a Telegram user. The file contained 8,166 records, each pairing an email address with a plaintext password and the URL of the account the credentials belong to.

Why This Is Dangerous

Every credential in this list is stored in plaintext and matched to a specific URL, which means an attacker does not need to crack a hash or guess which site a login works on. They can load the file straight into an automated tool and start testing thousands of logins within minutes of getting access to it.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linking each credential pair to its source site

Why This Matters

A list of over 8,000 working email and password combinations is a ready-made toolkit for credential stuffing, where attackers try the same login across banking sites, email providers, and social platforms in bulk. If you are one of the 8,166 people in this file and you have reused a password anywhere else, you are at risk of account takeover, identity theft, or financial fraud right now.

How Combolists Work

A combolist is a compiled file of email-and-password pairs, usually pulled from stealer malware infections, old breaches, or phishing hauls, then packaged under a short label like "RO" and shared or sold on Telegram channels and dark web forums. The short, cryptic naming is common; buyers often care more about the record count and password quality than the list's origin story.

Search Your Email to Check If You Are Affected

Rather than wonder whether your email is one of the 8,166 records in this leak, search it directly. HEROIC's free breach scanner checks your address against a database of more than 400 billion leaked records and tells you instantly if you need to change a password.
