How farmagol Built the LeakBase 50M ULP Stealer Log Dump

HEROIC analysts found the LeakBase 50M ULP by farmagol dataset on July 10, 2024, when it appeared on a prominent underground forum carrying the signature message "Good Luck" from threat actor farmagol. The post advertised approximately 50,000,000 lines of credential data, of which 7,450,011 records were unique. Each record contained an email address, a homepage URL, and a plaintext password, the most dangerous credential combination possible. This release is Part 1 of a multi-part series by the same actor; Part 2 is documented in LeakBase 50M ULP part 2 by farmagol.

Why This Is Dangerous

Plaintext passwords require no cracking. Any person who downloads this dataset can immediately attempt to log in to the accounts listed with no technical barrier. The inclusion of homepage URLs tells attackers exactly which services each credential pair is valid for, enabling precise, targeted account takeover rather than speculative stuffing across random platforms. This is a ready-to-use attack toolkit, not raw data.

What Was Exposed

• Email Address
• HomePage URL
• Plaintext Password

Why This Matters

Credential stuffing attacks powered by datasets like this one are the leading cause of account takeover fraud. Attackers who gain access to one account frequently pivot to banking, email, and e-commerce platforms where the same password was reused. Victims face unauthorized financial transactions, identity theft, and secondary breaches of personal information stored within compromised accounts. The scale of 7.4 million unique records ensures broad geographic and demographic impact.

How Database Breaches Work

Stealer log databases are compiled by infostealer malware running on infected endpoints. The malware silently captures credentials as users type them into browsers or auto-fill them from saved password stores, then packages and transmits the harvested data to attacker-controlled servers. The operator then aggregates logs from thousands of infected machines into bulk files and sells or freely distributes them on underground forums. The plaintext format is a direct product of how browser-stored credentials are captured.

Check If You Are Affected

HEROIC's free identity scanner checks your credentials against more than 400 billion exposed records, including stealer log datasets like this one. Run a scan now to find out whether your email address and passwords appeared in this or any related farmagol release.
