Identity Theft Just Got Easier Because of the Redline_Cloud4 Breach: 13.4 Million at Risk

HEROIC analysts added the FRESH ULPP 25-05-2026 file to the breach database after it appeared on Telegram in late May 2026, uploaded by a user operating as Redline_Cloud4. The archive contained 13,450,913 records pulled from machines infected with Redline Stealer malware. Each record includes an email address, a plaintext password, and the URL of the website where that password was used and saved. With more than 13 million entries, this is one of the larger individual stealer log uploads HEROIC analysts have catalogued from this actor series.

The file follows the ULPP format -- URL, Login, Password -- which is the standard structure for organized stealer log distributions. These are not random credential fragments. They are clean, structured records designed for immediate use by anyone who downloads the file. No technical skill is required to exploit them.

Why 13 Million Plaintext Passwords Make Identity Theft Significantly Easier

Identity theft and account fraud have always required a starting point. Before a criminal can drain your bank account, take out credit in your name, or hijack your email, they need something to get in. This file provides exactly that starting point for 13 million people. Every record contains a working email address and the password that was saved alongside it in a browser -- in plain text, with no encryption, no hashing, no barrier between the data and whoever reads it.

The URLs in each record remove any uncertainty about which service the password belongs to. An attacker does not need to guess whether your password works on your bank's website. If your banking login is in this file, they already know the URL, the email, and the password. They can go directly to your account.

At 13 million records, the probability that someone in your household, workplace, or social circle appears in this dataset is not negligible. These are not targeted victims. They are ordinary people whose computers were infected by malware distributed through everyday downloads.

What the Redline_Cloud4 FRESH ULPP File Exposed

• Email addresses (13.4 million unique accounts at risk)
• Plaintext passwords (no cracking required, immediately usable)
• URLs (exact destination websites for each stolen credential)

The FRESH designation confirms these credentials were recently harvested and had not previously been widely distributed, increasing the likelihood that passwords had not yet been changed at the time the file was posted.

How This Breach Connects to Financial Fraud and Identity Theft

A plaintext credential with a known target URL is the single most useful item a financial fraudster can obtain. Email account access enables password resets on every linked service. Banking login access enables immediate fund transfers. Shopping account access exposes stored payment cards and shipping addresses. Each of these leads directly to the next.

Researchers consistantly document cases where a single stolen credential leads to compromise across six or more accounts within hours. Attackers use the email account as a master key -- resetting passwords on linked services, intercepting verification codes, and methodically working through every account associated with that address.

With 13.4 million starting points in this one file, the potential downstream impact across the global internet is significant. Credential stuffing tools allow one attacker to process thousands of records per hour, meaning the window between this file appearing on Telegram and accounts being compromised was measured in days, not weeks.

How Redline Stealer Generates Files Like This One

Redline Stealer is sold as a commercial tool on criminal markets. It is designed to be easy to use -- even someone with minimal technical knowledge can configure it, embed it in a malicious file, and start collecting credentials. The malware targets saved passwords in Chrome, Firefox, Edge, and other popular browsers, pulling them out along with session cookies, form autofill data, and any cryptocurrency wallet files it finds on the machine.

Once infeccion occurs, the harvested data is compressed into a log file and uploaded to the attacker's collection server. The actor then organizes the logs into structured ULPP format files and posts them to Telegram channels where other criminals can download or purchase them. The FRESH label signals that these logs have not yet been widely shared, which increases their percieved value in criminal markets.

Victims typically discover the breach only after experiencing account lockouts, unauthorized transactions, or when a tool like HEROIC's breach scanner flags their email in a database like this one.

Check If You Are in the Redline_Cloud4 FRESH ULPP File

With 13.4 million records in this single upload, checking your email is not optional -- it is necessary. HEROIC's free breach scanner searches across more than 400 billion exposed records, including this Redline_Cloud4 file and thousands of other breach datasets, and returns results within seconds.

Enter your email at HEROIC to find out if your credentials appear in this dataset. If they do, change your passwords on every account immediately, enable two-factor authentication wherever it is available, and revoke any active sessions you do not recognize. The sooner you act, the smaller the window attackers have to use your data.
