US Users Dominate the LeakBase 200M ULP by 19890036580 Credential Dump

HEROIC's DarkHive analysts pulled a 200 million line stealer log off a Russian-language hacking forum on November 30, 2024, uploaded by the handle 19890036580 and titled 200M Url Login Pass (Not Mine). After deduplicating the file against our 400B+ record index, LeakBase 200M ULP by 19890036580 was confirmed to contain 21,655,216 unique users, with a heavy concentration of United States email domains. Each record carries an email address, a plaintext password, and a homepage URL.

Why This Stealer Log Is Dangerous

LeakBase 200M ULP by 19890036580 is one of the largest credential dumps posted in 2024, and the US skew means national brands, banks, and social platforms dominate the target list. Credential stuffing automation chews through tens of millions of login attempts per day, and the hit rate on fresh plaintext pairs is high.

What Was Exposed in LeakBase 200M ULP by 19890036580

• 21,655,216 unique email addresses
• Plaintext passwords with zero hashing
• HomePage URLs mapping credentials to specific services
• 200 million total harvested credential lines

Why This Matters

With US-based users dominating the dump, the real-world impact hits banking portals, payroll systems, and streaming accounts hardest. Attackers can also pivot into W-2 fraud and tax refund scams because tax season opens while the dump is still fresh in circulation.

How Database Credential Theft Works

Infostealer malware infects user devices through pirated software, malicious browser extensions, and phishing attachments. It exports browser-stored credentials, session cookies, and autofill data to a command and control server. Brokers like 19890036580 then aggregate outputs into massive ULP dumps and post them on forums, typically to build reputation or to sell access to premium tiers.
