The 40k Streaming Base Leak: 40,017 Passwords Are Exposed

40,017 Passwords Exposed in the 40k Streaming Base Leak. On December 24, 2022, a Telegram user uploaded a combolist file called 40k Streaming Base. HEROIC's threat intelligence team identified and verified the listing on July 31, 2026, confirming it contains 40,017 records of email addresses, plaintext passwords, and associated URLs tied to streaming accounts. Why This Is Dangerous. The passwords in this file sit in plaintext, meaning anyone who grabs the file can log in immediately with no cracking involved. Because the URLs point straight to the streaming platforms these accounts belong to, an attacker can take over a subscription instantly, or use the same email and password to try other services the victim might use. What Was Exposed: Email addresses. Plaintext passwords. Associated login URLs. Why This Matters. Streaming accounts often share a password with email, banking, or shopping logins, and a leak of this size gives attackers 40,017 chances to find a match. Once inside, criminals commonly resell the accounts, lock out the original owner, or use the same credentials to attempt credential stuffing against higher value targets like financial accounts. How Combolists Work. A combolist pairs stolen emails or usernames with passwords in a single text file, typically gathered from older breaches, phishing pages, or malware and repackaged for quick distribution. Files like the 40k Streaming Base leak require no technical skill to use, which is exactly why they spread fast on Telegram once uploaded. Check If You Are Affected.
