LeakBase 8Kk ULP by Firegoon: 3,376,450 Records Confirmed Exposed
HEROIC analysts found that on July 15, 2024, a stealer log labeled "8Kk Url:log:pass" was published on a prominent underground hacking forum by the threat actor firegoon, operating through the LeakBase platform. The log exposed 3,376,450 unique records from an estimated 8 million total entries, each consisting of an email address paired with a plaintext password and an associated HomePage URL. This release is part of a documented series of credential dumps by the same actor. Related releases include LeakBase 7.8Kk ULP by firegoon, LeakBase 8.8Kk ULP by firegoon, LeakBase 10.8Kk ULP by firegoon, and LeakBase 10.8Kk ULP #2 by firegoon.
Why This Is Dangerous
Plaintext password leaks eliminate the time buffer that hashed credentials provide. There is no cracking phase: credentials are ready to use the moment a file is downloaded. With 3,376,450 unique email-password-URL triplets available, the data supports highly targeted credential stuffing campaigns. The URL field removes guesswork, directing attackers to the precise services where each credential was active.
What Was Exposed
- Email Address
- HomePage URL
- Plaintext Password
Why This Matters
Credential stuffing and account takeover (ATO) are the primary risks from a dataset of this structure. Automated attack tools can test millions of credential pairs per hour across banking portals, e-commerce sites, email providers, and social platforms. For individuals who reuse passwords, a single entry in this log can unlock multiple accounts simultaneously, enabling financial fraud, identity theft, and unauthorized access to sensitive personal and professional data. The repetitive nature of firegoon's releases indicates an active, ongoing operation rather than a one-time event.
How Database Breaches Work
This type of leak originates from infostealer malware running on compromised end-user devices. The malware extracts credentials saved in web browsers and applications, captures the associated URLs, and transmits the harvested data to attacker-controlled infrastructure. Records are then aggregated and published in bulk on forums like LeakBase. Because the data comes from individual devices rather than a single corporate database, a single log can contain credentials for hundreds of different online services.
