Search Your Email: The Redline_Cl0ud4 ULPP Leak Hit 3.1 Million Accounts

On May 30, 2026, HEROIC's monitoring team flagged another ULPP file, this one uploaded by Redline_Cl0ud4 and dated May 29 in the file name. The dump contains 3,114,103 records, each pairing an email address with a plaintext password and the exact web address the login belongs to. This is the second large ULPP release from the same uploader in under a month, a sign that whoever is behind Redline_Cl0ud4 has a steady pipeline of freshly infected machines feeding them data.

Why This Is Dangerous

With over 3 million working logins in one file, this isnt a random scattershot list, its organized, sortable, and ready for automated attacks the moment it's downloaded. Criminals routinely run these files through credential-stuffing tools that test each login against dozens of popular sites in seconds, looking for any account where the password still works.

What Was Exposed in the May 2026 Redline_Cl0ud4 Dump

• 3,114,103 email addresses connected to real accounts
• Plaintext passwords with zero encryption protecting them
• The specific URL tied to each stolen login

Why This Matters

A dump this size touches an enormous number of everyday people, and the risk goes well beyond the original site the password was stolen from. Reused passwords let one leaked login unlock email, banking, and shopping accounts alike, opening the door to account takeover, unauthorized transactions, and identity theft that can take months to fully undo.

How Repeated Redline_Cl0ud4 Dumps Get Made

Uploaders like Redline_Cl0ud4 typically run or resell access to infostealer malware, software that silently harvests browser passwords, cookies, and autofill data from every machine it infects. Rather than release one giant file, these operators often break their harvested data into dated batches, like this ULPP release, to keep their Telegram channel active and their buyers coming back for the next drop.
