Search Your Email: The LeakBase 50Kk ULP by farmagol Exposed 8.5 Million Accounts

On October 2, 2024, a stealer log called LeakBase 50Kk ULP by farmagol surfaced on a well-known hacking forum, claiming 50 million user records with 8,538,568 unique entries confirmed. The dataset contained email addresses, homepage URLs, and plaintext passwords, making it immediately actionable for anyone looking to take over accounts. If you have an online account and reuse passwords, there is a real chance your credentials are in this dump. Use the HEROIC search tool below to find out.

This leak is part of a broader pattern of ULP (URL:Login:Password) combo list releases on underground forums, where threat actors aggregate harvested credentials from stealer malware infections and package them for distribution. The LeakBase series alone accounts for hundreds of similar releases. This post covers the 50Kk release by the actor farmagol.

Why This Is Dangerous

Stealer logs like this one are not theoretical. They are structured, searchable credential dumps handed directly to threat actors. Because the passwords in this dataset are plaintext, they require zero effort to use. Anyone with the file can attempt to log into the email accounts, banking portals, and social media profiles associated with each entry immediately. The 8.5 million unique records represent 8.5 million live attack opportunities.

What Was Exposed

• Email addresses (8,538,568 unique records)
• Homepage URLs (the site where the credential was captured)
• Plaintext passwords (unencrypted, immediately usable)

Why This Matters

When plaintext passwords circulate in a credential dump, the downstream risks multiply quickly:

• Credential stuffing: Automated tools test these email/password pairs across hundreds of sites simultaneously. If you reuse your password, multiple accounts fall at once.
• Account takeover: Email account access lets attackers reset passwords on every other service tied to that address.
• Identity theft: Combined with the homepage URL showing where the credential was active, attackers know exactly which platforms to target.
• Fraud: Access to financial accounts, e-commerce profiles, and subscription services can result in direct monetary loss.

How Stealer Log Breaches Work

ULP stealer logs are typically generated by infostealer malware, such as RedLine, Vidar, or Raccoon. These programs infect a device, silently extract saved browser credentials, and transmit them to a command-and-control server controlled by the attacker. The harvested credentials are then packaged into structured lists formatted as URL:Login:Password (ULP) and sold or posted on hacking forums. The "50Kk" designation refers to the claimed 50 million record count. The actor farmagol posted this on LeakBase, a prominent forum known for hosting large credential compilations.

Check If You Are Affected

HEROIC's breach database contains over 400 billion compromised records. Search your email address to see if it appears in this or any other known breach. Early detection gives you time to change passwords, enable two-factor authentication, and lock down your accounts before attackers act.
