37,334 Passwords Exposed in URL_Pass_Log Stealer Leak: Check Now

In late December 2025, HEROIC analysts identified a stealer log file labeled "url_pass_log," uploaded to a Telegram channel by an unidentified user. The file contained 37,334 records pairing email addresses with plaintext passwords and the exact URLs of the login pages they unlocked, harvested from devices infected with information-stealing malware.

Why the URL_Pass_Log Leak Is Dangerous

This isn't a list of usernames alone, it's more than 37,000 ready-to-use logins. Each record links a password directly to the website it belongs to, so an attacker doesn't need to guess where a stolen password might work. Because the passwords are stored in plaintext, no decryption or cracking is needed: anyone who downloads the file can start testing logins immediately.

What Was Exposed in the URL_Pass_Log Leak

• 37,334 email addresses used as account logins
• Plaintext passwords tied to each email
• The exact URLs each credential pair was used to access

Why This Matters for Anyone Reusing Passwords

With more than 37,000 credential pairs in circulation, this file is large enough to be repurposed for automated credential stuffing attacks, where criminals feed stolen email-password combinations into login forms across the web at scale. If you reused a password from one of these accounts anywhere else, especially on email, banking, or shopping sites, this leak raises your risk of account takeover, financial fraud, and identity theft.

How the URL_Pass_Log Stealer Log Was Likely Built

Stealer logs are produced by information-stealing malware that infects a victim's device, often through a malicious download or phishing link, and quietly copies everything saved in the browser: usernames, passwords, autofill data, and the URLs tied to each login. The malware bundles this stolen data into a single file, which is sent back to whoever controls the infection. From there, files like this one are commonly sold, traded, or shared for free on Telegram channels, exactly where HEROIC analysts found this one.
