Analysts Trace the 38K Mail Access Mix Leak to 38,451 Stolen Logins

HEROIC analysts traced a stealer log dump called "38K Mail Access Mix" to a Telegram upload dated March 19, 2026. The file contains 38,451 records, each one built from a website URL, an email address, and the plaintext password used to log into it, all pulled from malware-infected machines.

Why the 38K Mail Access Mix Is Dangerous

This particular batch is labeled "mail access," meaning the credentials inside were specifically verified to log into email inboxes. Email access is one of the most valuable things an attacker can get, becuase most password reset links for other accounts go straight to your inbox. Whoever holds this file can potentially reset passwords on banking, shopping, and social media accounts just by controlling the email address tied to them.

What Was Exposed

• 38,451 verified login records
• Email addresses confirmed to be accessible
• Plaintext passwords for each account
• URLs showing exactly where each credential works

Why This Matters

Email inboxes are the master key to a person's online life. Once an attacker controls an inbox, they can trigger password resets across dozens of other services, lock the real owner out, and quietly commit identity theft or financial fraud before anyone notices somthing is wrong.

How Mail Access Stealer Logs Get Made

Info-stealing malware infects a device through a phishing link or bundled software, then scans the browser for saved logins and active sessions. Criminals then test each captured credential against its own login page to confirm it still works, sorting out the ones labeled "mail access" because verified email logins sell for a premium on dark web markets and Telegram channels.

Check If You Are Affected

If your email login is part of a verified dump like this one, every account linked to that inbox is at risk. HEROIC's free breach scanner checks your email against more than 400 billion exposed records so you can see right away if you need to change your password.
