Your Data Is Already Out There. The LeakBase 13,4Kk Firegoon Dump Confirms It.

Your data is already out there. On October 30, 2024, a threat actor known as firegoon posted a massive stealer log to a prominent underground hacking forum under the name "13,4Kk Url:log:pass." The post claimed 13.4 million total credential entries. Analysis confirmed 678,540 unique records, each containing a plaintext email address, plaintext password, and the URL of the site where those credentials were stolen. This is part of the ongoing LeakBase ULP (URL:Login:Password) dump series from firegoon, one of the most prolific actors in credential log distribution. See Related Parts at the bottom of this page for other dumps in the same series.

Why This Is Dangerous

At 678,540 unique records, this is among the larger individual stealer log releases in this series. Plaintext passwords require no cracking — every credential in this dump is immediately usable. Attackers who access this log can begin hitting target accounts within minutes of downloading the file. The sheer volume means the log almost certainly contains credentials for financial accounts, email inboxes, healthcare portals, and enterprise applications.

What Was Exposed

• Email addresses
• Plaintext passwords
• Homepage URLs (the specific websites where each credential was harvested)

678,540 unique records confirmed from a claimed total of approximately 13.4 million entries.

Why This Matters

Credential dumps of this type are used directly for:

• Credential stuffing — automated login attempts across banking, email, retail, and enterprise platforms
• Account takeover — direct access to any account where the exposed password is still active
• Identity theft — exploiting account access to harvest personal data stored inside those accounts
• Financial fraud — draining payment methods, gift card balances, and loyalty points stored in compromised accounts

How Stealer Logs Work

Infostealer malware is distributed through phishing lures, pirated software installers, malicious browser extensions, and compromised ad networks. Once installed on a victim's device, it silently extracts saved credentials from browsers and applications, pairing each password with the associated site URL. These credentials are bundled into logs and either sold privately or posted publicly on forums like the one where this dump appeared. Because the theft happens at the device level, the credentials are valid at the time of collection and often remain active for months or years before the user changes their password.

Check If You Are Affected
