Comcast112 Telegram Leak Exposed 125 Plaintext Passwords

Comcast112: A Telegram Combolist Exposing 125 Credentials

In May 2026, HEROIC analysts identified a combolist known as comcast112, uploaded to Telegram by an anonymous user. The file contained 125 records pairing email addresses with plaintext passwords, along with the URLs the credentials were tied to. Unlike a single corporate data breach, this file is a compiled list of stolen login credentials, the kind of resource threat actors trade and reuse across the dark web.

Why This Is Dangerous

Because the passwords in this combolist were stored and leaked in plaintext, no cracking or decryption is required. Anyone who obtains this file can immediately try the exposed email and password pairs against other websites, banking apps, or corporate logins. If any of the 125 people affected reused a password across multiple accounts, a single leaked credential can unlock an entire digital footprint, from email to social media to financial services.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs (the sites the credentials were used on)

Why This Matters

Combolists like comcast112 are the fuel behind credential stuffing attacks, where automated tools test stolen email and password combinations against thousands of websites in seconds. Because the passwords here are already in plaintext, attackers skip the hardest step entirely. This directly raises the risk of account takeover, identity theft, and financial fraud for anyone whose credentials appear in the file.

How Combolists Work

A combolist is a simple text file that pairs usernames or emails with passwords, usually gathered from older breaches, phishing campaigns, or malware infections and then repackaged for resale or free distribution on platforms like Telegram. Criminals value combolists because they require no technical skill to use. They load the file into automated login-testing software and let it run against popular sites until it finds a match.

Check If You Are Affected

If you have ever used an email address tied to this leak, or if you reuse passwords across accounts, it is worth finding out now rather than after an account is compromised. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including combolists like comcast112, so you can see your exposure and take action before criminals do.
