880K Streaming UHQ Mix Leak: 844,248 Logins Exposed Online

Inside the "880K Streaming UHQ Mix Data" Leak: 844,248 Records Exposed

On February 28, 2023, HEROIC analysts identified a stealer log dataset shared by a Telegram user under the label "880K Streaming UHQ Mix Data." The file contained 844,248 records, and each one paired an email address with a plaintext password and the URL of the site that login was used on. The "streaming" tag in the file's name points to logins connected to streaming service accounts specifically.

Why This Streaming-Focused Stealer Log Is Dangerous

Zoom in on a single record in this file and you see the whole problem: one email address, one plaintext password, and the exact streaming site it unlocks. Multiply that by 844,248 and you have a massive, ready-to-use list of working logins that requires no cracking or guessing to exploit.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs identifying the site each login was used on

Why This Matters

Streaming account credentials are frequently reused on other, more sensitive accounts, so this dataset is well suited to credential stuffing attacks that test the same email and password combination across banking, shopping, and email services. Anyone among these 844,248 people who reused a streaming password elsewhere faces a real risk of account takeover far beyond the streaming service itself. The included URL makes each login attempt faster and more precise for an attacker.

How Stealer Logs Work

Stealer logs are the output of malware that infects a device and quietly copies saved browser passwords, autofill data, and site URLs before sending it all back to the attacker running the malware. People typically get infected through pirated software, fake installers, or malicious attachments. Once collected, this kind of data is often sorted by category, such as streaming accounts, and traded on Telegram channels and dark web forums.
