More People Than Kentucky: The Redline_Cl0ud4 Password Leak

4.6 Million Records in the Redline_Cl0ud4 ULPP Dump

On May 6, 2026, a Telegram uploader going by Redline_Cl0ud4 posted a fresh batch of stolen credentials labeled "ULPP" (URL, login, password pairs). HEROIC analysts confirmed the file contains 4,660,849 individual records, each combining an email address, a plaintext password, and the web address where the login was captured. To put that number in perspective, it's more records than there are people living in the entire state of Kentucky.

Why This Is Dangerous

Every entry in this dump came straight from an infected device, not a guessed password list. That means the credentials are current and, in many cases, still valid. Attackers dont need any special skill to use them: they load the file into automated loggin-testing software and let it run against banking sites, email providers, and shopping accounts overnight.

What Was Exposed in the Redline_Cl0ud4 ULPP Leak

• Email addresses linked to active online accounts
• Plaintext passwords with no hashing or encryption
• URLs identifying the exact site each credential unlocks

Why This Matters

Because the data is organized as clean email, password, and URL trios, it's ready-made for credential stuffing attacks the moment it hits Telegram. If you reused a password across more than one site, one leaked login can quickly turn into a chain reaction of account takeovers, drained loyalty points, hijacked email, and eventually identity theft or financial fraud.

How the Redline_Cl0ud4 Stealer Log Was Built

Files like this come from infostealer malware, a category of malicious software that infects a computer through pirated downloads, fake browser updates, or malicious attachments. Once installed, it quitely pulls saved passwords and autofill data straight out of the browser and ships them back to whoever is running the malware. The attacker then bundles the results into a text file, like this ULPP dump, and either sells it or gives it away on Telegram to build a reputation in the underground community.
