The LeakBase 800K ULP Leak Could Unlock Your Email, Bank, and Social Media

On November 13, 2024, a stealer log titled 738K ULP appeared on a prominent hacking forum. Posted by a threat actor known as farmagol and tracked under the LeakBase 800K ULP dataset, the dump contained approximately 800,000 records exposing 308,361 unique email addresses paired with plaintext passwords and homepage URLs. Because the passwords were never encrypted, anyone with access to this file can immediately attempt to log in to every service those victims use -- no cracking required.

Why This Is Dangerous

Plaintext credential dumps are among the most operationally ready attack tools in the cybercriminal ecosystem. Unlike hashed password dumps that require brute-force cracking, these credentials are plug-and-play. A single compromised email-and-password pair can cascade into bank account takeovers, social media hijacks, email inbox access, and identity fraud -- especially when victims reuse passwords across services.

What Was Exposed

• 308,361 unique email addresses
• Plaintext passwords -- fully readable, no decryption needed
• Homepage URLs -- indicating which sites the credentials belong to

Why This Matters

The combination of email, plaintext password, and site URL creates a ready-made credential stuffing kit. Threat actors use automated tools to test these combos across banking portals, email providers, e-commerce sites, and social platforms within hours of a dump appearing. Key downstream risks include:

• Credential stuffing -- automated login attempts across hundreds of services
• Account takeover -- full control of email, banking, and social accounts
• Identity theft -- personal data harvested from compromised inboxes and profiles
• Financial fraud -- unauthorized transactions, loan applications, and wire transfers

How Stealer Log Breaches Work

Stealer malware -- such as RedLine, Vidar, and Raccoon -- infects devices through malicious downloads, phishing links, or compromised software installers. Once installed, the malware silently harvests credentials stored in browsers, password managers, and application login caches. The extracted data is packaged into logs and sold or shared on underground forums. The "ULP" (URL-Login-Password) format seen here is a direct output of this process: every row contains the target website, the username, and the password in plain text.
