LeakBase 14Kk ULP by firegoon Adds 1.5M Logins to Criminal Combolists

On December 10, 2024, HEROIC's dark web monitoring captured the LeakBase 14Kk ULP by firegoon stealer log posted to a prominent hacking forum. The raw file contains approximately 14 million lines and deduplicates to 1,501,480 unique records, each pairing an email address with a plaintext password and the homepage URL where the credential was harvested.

Why This Stealer Log Is Dangerous

Firegoon's log slots directly into the existing LeakBase ecosystem where buyers routinely merge fresh drops with older combolists. Even if your password was rotated in 2023, any credential harvested since then that appears here becomes active ammunition. The URL field in each record removes guesswork, dramatically boosting attack success rates.

Why This Matters

LeakBase operates as a curated hub where multiple threat actors publish stealer logs tagged by handle and size. Posts from recurring operators like firegoon signal to buyers that the data has been pre-filtered. The forum reputation economy ensures fresh logs reach tens of thousands of attackers within hours. Every new release widens the attack surface for anyone whose saved browser password was captured by infostealer malware in the last year.

How Stealer Log Breaches Work

Infostealer malware like RedLine, Lumma, Vidar, and StealC reaches victims through cracked software, pirated games, malvertising, and phishing attachments. Once active, the malware harvests saved browser passwords, cookies, autofill data, and crypto wallet files, then uploads the log to the attacker. Operators like firegoon aggregate thousands of individual logs and brand them for forum distribution.
