Streaming Fans Targeted: 3KK Private Base Leaked 2.98M Passwords

In March 2023, HEROIC analysts identified a massive stealer log advertised as "3KK Private Streaming Base" circulating on a Telegram channel. HEROIC's analysis confirmed 2,984,498 records in the file, including email addresses, plaintext passwords, and the URLs each login was tied to. As the name suggests, the credentials in this base are focused heavily on streaming service logins, making it one of the largest streaming-focused stealer logs HEROIC analysts have tracked.

Why This Is Dangerous

Streaming accounts are often treated as low stakes, but that assumption is exactly what makes a base like this so dangerous. Each of the nearly 3 million records pairs an email address with its plaintext password and the exact streaming site it unlocks, giving an attacker instant, working access. Because streaming logins are frequently reused from other accounts, gaining access to one can be the first step toward reaching a victim's email, banking, or shopping accounts as well.

What Was Exposed

This leak included the following data types:

• Email addresses
• Plaintext passwords
• URLs linked to each set of credentials, largely tied to streaming platforms

Why This Matters

At nearly 3 million records, this base is built for large-scale credential stuffing, where attackers test stolen email and password pairs across streaming services, then pivot to banking, email, and social media accounts using the same reused password. Beyond direct account takeover, stolen streaming logins are also commonly resold cheaply in bulk on their own, letting criminals profit from access long after the original theft, while the account owner keeps paying for a subscription someone else is using.

How Stealer Logs Work

A stealer log comes from information-stealing malware, malicious software that infects a device through cracked software, fake downloads, or phishing attachments, then silently extracts saved browser passwords and active sessions. A streaming-focused "private base" like this one is typically built by combining millions of individual stealer logs and filtering specifically for entertainment platform logins, since streaming credentials are in high demand among buyers looking for cheap, easy access to paid services.

Check If You Are Affected

With 2,984,498 records in this single base, the odds that your streaming or email login is included are significant. HEROIC's free breach scanner checks your email against a database of more than 400 billion leaked records, including stealer logs like this one, so you can find out quickly and update any reused passwords before someone else uses your accounts.
