37K Edo Domain Base Leak: 33,107 Emails and Passwords Exposed

HEROIC Analysts Flag the "37K Edo Domain Base" Stealer Log

In April 2023, HEROIC's threat intelligence team identified a stealer log shared on Telegram under the name "37K Edo Domain Base." The file contained 33,107 records, and each one combined an email address, a plaintext password, and the URL of the site that credential logged into. It is now cataloged in HEROIC's breach intelligence database so anyone affected can check their exposure.

Why a Password Matched to a Working URL Is More Dangerous Than a Simple List

A password by itself isn't very useful to a criminal unless they know where to use it. In the 37K Edo Domain Base log, every plaintext password comes pre-matched with the email address and URL it belongs to. That removes the guesswork entirely: an attacker can plug the combination straight into the real login page and get in, no cracking or trial-and-error required. This is the exact format automated credential-stuffing tools are designed to run through in bulk.

What Was Exposed in the 37K Edo Domain Base Log

• Email addresses tied to each victim
• Plaintext passwords, stored without encryption
• URLs identifying the exact login page each credential pair unlocks

Why This Matters Even If You Don't Recognize "Edo Domain Base"

Names like this one come from whoever uploaded the file, not from a company you'd recognize, so most victims have no idea the log even exists. That doesn't reduce the risk. If your email and password show up in this file and you've reused that password anywhere else, including email, banking, or shopping accounts, an attacker can move from one account to the next using the exact same credentials. This is how a single leaked password can quietly turn into full account takeover and, eventually, identity theft.

How Uploaders Turn Raw Malware Logs Into a "Domain Base" File

Information-stealing malware infects devices through cracked software, fake downloads, or phishing links, then quietly copies passwords saved in the victim's browser along with the web addresses they're used on. Whoever collects these logs often sorts the results by domain or theme before sharing them, which is why this file is labeled a "domain base" rather than tied to one single company. The result is a ready-to-use credential list built from many different victims and websites, not one central breach.

Check If You're One of the 33,107 Records in This Leak

The only way to know for certain is to check. HEROIC's free breach scanner searches a database of more than 400 billion leaked records, including stealer logs like the 37K Edo Domain Base file, and tells you instantly if your email address turns up. If it does, change that password right away, stop reusing it anywhere else, and turn on two-factor authentication wherever you can.
