One Telegram Combolist Leaked 2,765 Roofing Company Logins

In August 2026, HEROIC analysts spotted a combolist file circulating on Telegram, labeled "10k_roofing_companies" and uploaded by a Telegram user. The file contained 2,765 records pairing email addresses with plaintext passwords and associated URLs, specifically targeting accounts tied to roofing businesses.

Why This Roofing Company Combolist Is Dangerous

Every password in this file is stored in plaintext, meaning anyone who grabs the list can read every credential instantly without cracking anything. Because these accounts belong to small businesses, a compromised login can give an attacker access to business email, customer records, or financial tools that a roofing company depends on daily.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Small business owners are attractive targets precisely because they often lack the security resources of larger companies. If your credentials are among the 2,765 exposed records, an attacker can attempt automated logins across other business accounts you use, a tactic called credential stuffing. That can quickly lead to business email compromise, financial fraud, or identity theft for the account holder.

How Industry-Targeted Combolists Get Built

A combolist is a compiled file of email or username and password pairs, often assembled from earlier breaches, phishing campaigns, or malware infections. Lists organized around a specific industry, like this one focused on roofing companies, let attackers target a niche of business owners at once, using shared vendor platforms or industry software as a common thread to test stolen credentials against.

Check If Your Business Login Was Exposed

If you want to know whether your email address appears in this combolist or any other leaked dataset, HEROIC's free breach scanner checks your information against a database of more than 400 billion leaked records. It takes seconds to check, and if you find a match, changing that password everywhere you have reused it is the fastest way to protect your business.
