How a Telegram Combolist Exposed 849 Login Credentials for Comcast.et

HEROIC analysts traced a combolist that surfaced in a Telegram channel on 10-Jun-2026, containing 849 records tied to comcast.et. The file pairs email addresses with plaintext passwords and related URLs, meaning the credentials are ready to use the moment someone downloads the file, no extra work required.

Why This Is Dangerous

Plaintext passwords are the easiest kind of stolen data to abuse. There is no encryption to break and no hash to crack, an attacker can simply copy each email and password pair straight into a login form. With 849 accounts in this file, anyone who reused their comcast.et password on another site has effectively handed that account over as well.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs linking accounts to specific login pages

Why This Matters

Files like this are the fuel behind credential stuffing campaigns, where attackers run stolen email and password pairs against banking portals, email accounts, and social media in bulk. A single reused password from this leak can lead to account takeover, identity theft, or direct financial fraud, even for people who never expected their comcast.et login to matter.

How This Combolist Happened

Combolists like this one are typically compiled by combining data from older breaches, phishing pages, or stealer malware logs, then packaged into a single text file and shared on Telegram or dark web marketplaces. Because assembling one takes little technical skill, this kind of leak can circulate widely within hours of being posted, often long before the people affected ever find out.
