RedLine Stealer Malware Targeted 12,552 Login Credentials

HEROIC analysts found a RedLine stealer log, labeled "14K FRESH MIX HITSS Redline_Cl0ud4 2," that a Telegram user uploaded with data dated to May 13, 2026. The file contains 12,552 records of email addresses, plaintext passwords, and associated URLs, all pulled from devices infected with RedLine malware and packaged for anyone looking to use the stolen logins.

Why This Is Dangerous

Each of the 12,552 entries in this leak pairs a working email address with its plaintext password and the exact site it unlocks. That combination removes the guesswork for an attacker, who can attempt to log directly into each account without needing to crack, guess, or reset anything first.

What Was Exposed

• Email addresses
• Plaintext passwords
• Associated URLs

Why This Matters

Leaks of this size are commonly used for credential stuffing, where attackers run automated tools to test each stolen email and password pair against banking sites, email providers, and social media platforms. Anyone in this leak who reused a password on another account faces a real risk of account takeover, and once an attacker gains access to one account, they often have enough information to attempt identity theft or financial fraud elsewhere.

How RedLine Stealer Malware Works

RedLine is malware that infects a device, commonly through a malicious download, cracked software, or a phishing link, and then silently collects saved passwords, autofill data, and browsing details from the browser without the victim noticing. That harvested information is compiled into a stealer log and distributed through Telegram channels and underground forums, which matches how this file surfaced. Because the credentials are lifted directly from a real, active browser session, they tend to be accurate and immediately usable.
