One Telegram Post, 13.2 Million Logins: The Big King Streaming Base

HEROIC analysts have indexed a combolist file called “13.2KK Big King Streaming Fresh Base uploaded by a Telegram User,” which was shared on Telegram on April 2, 2023. The file contains 13,217,895 records tied primarily to accounts in the United States, pairing email addresses and usernames with plaintext passwords and the URLs those credentials unlock.

Why This Is Dangerous

Over 13.2 million email and password pairs sit in this single file, each one matched to the exact site it logs into. Because the passwords were stored in plaintext, there is no encryption for an attacker to work around. Anyone who downloads this file can start testing logins the moment it lands in their hands, no cracking or guesswork needed.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials

Why This Matters

A leak of over 13 million credential pairs gives attackers massive scale for credential stuffing, automatically testing stolen email and password combinations against banking sites, email providers, and other online services. Anyone caught in this file who reused their password elsewhere faces a real risk of account takeover, and a compromised email account can become the key to resetting passwords on other services, opening the door to identity theft and financial fraud.

How Combolists Work

A combolist is a compiled file of email or username and password pairs, usually gathered from earlier breaches and stealer logs and organized into a single, searchable list. Criminals distribute combolists like this one through Telegram channels because the format makes it easy to feed into automated tools that test each pair against many login pages at once. The 13.2KK Big King Streaming Fresh Base file follows this pattern, bundling over 13 million credential pairs together with the URLs needed to use them immediately.
