Stealer Log Economy at Scale: FFish Drops 17.2M Credentials on LeakBase

HEROIC Cyber's DarkHive breach intelligence has confirmed that LeakBase 220M+ ULP Part 2 by FFish, a stealer log dump posted on December 27, 2024, contains 17,221,361 unique compromised records. The file pairs email addresses with plaintext passwords and the exact homepage URLs where each login was captured, a format tuned for immediate credential stuffing.

Why This Stealer Log Dump Is Dangerous

At 17.2 million unique credentials, this single part of the 220M+ ULP series is larger than the entire customer base of many regional banks. Each entry came from an endpoint already infected with infostealer malware, meaning criminals received pre-validated email and password combinations linked to the real sites victims were using when the data was siphoned.

What Was Exposed in LeakBase 220M+ ULP Part 2 by FFish

• 17,221,361 unique records
• Email addresses
• Plaintext passwords
• HomePage URLs for every credential pair

Why This Matters

Once credentials land in a ULP (URL Login Password) dump on LeakBase, automation takes over within hours. Bot networks replay the logins across banks, cloud email, retail accounts, and corporate VPNs. Because the dump names the target URL next to the password, attackers avoid wasted attempts and go straight to accounts they know exist.

How Stealer Log Database Dumps Work

Infostealer families like RedLine, StealC, and Lumma scrape saved logins from browsers on infected devices. Operators such as FFish buy or steal these logs, combine them into multi-million record bundles, and release them in parts on forums like LeakBase. Even aged credentials stay useful because password reuse across sites is still the norm for most users.
