The LeakBase STARLINK 19M ULP Leak Exposed 3.5 Million Accounts Worldwide

On November 12, 2024, a threat actor operating under the name VitVit uploaded a massive stealer log to a prominent underground forum. Titled "Best Private Url:login:pass 19+ Million Lines" and catalogued under the LeakBase STARLINK 19M ULP dataset, the dump contained over 19 million records. Of those, 3,508,289 unique email addresses were identified alongside their plaintext passwords and associated homepage URLs. The geographic breadth of the affected accounts -- spanning users worldwide -- makes this one of the more expansive individual stealer log releases of late 2024.

Why This Is Dangerous

At 3.5 million unique credentials in plaintext format, this dump represents an immediately weaponizable dataset. Attackers do not need to crack or reverse-engineer anything -- they can begin testing credentials against banking, email, social media, and subscription services the moment the file is downloaded. The scale virtually guarantees that a significant portion of victims reuse these passwords elsewhere.

What Was Exposed

• 3,508,289 unique email addresses
• Plaintext passwords -- no hashing, no encryption, immediately usable
• Homepage URLs -- identifying the specific sites from which credentials were harvested

Why This Matters

A dump of this scale creates serious downstream risk for millions of people. Even users who have not heard of "STARLINK" or "VitVit" may have had their credentials captured by the same malware campaign that fed this log. Key threats include:

• Credential stuffing -- automated attacks testing these logins across thousands of sites simultaneously
• Account takeover -- email and social media accounts hijacked within hours of a dump's release
• Identity theft -- personal data mined from compromised accounts used to open fraudulent credit lines
• Financial fraud -- banking and payment accounts drained or used for unauthorized purchases

How Stealer Log Breaches Work

Infostealer malware -- including well-known strains like RedLine, Vidar, and Raccoon Stealer -- spreads through phishing emails, malicious browser extensions, cracked software downloads, and drive-by infections. Once on a device, the malware silently extracts saved credentials from browsers and applications, packaging them into URL-Login-Password (ULP) formatted logs. These logs are then sold or freely distributed on underground forums, enabling large-scale credential attacks. The "STARLINK" label in this dataset likely refers to a distribution channel or malware campaign name rather than the satellite internet provider.
