Identity Theft Risk Rises After the Winter Cloud Free 1 Leak

HEROIC analysts found a stealer log file called "Winter Cloud Free 1" circulating on Telegram, containing 11,242 records of email addresses, plaintext passwords, and the URLs tied to each login. The data was originally captured in August 2023.

Why the Winter Cloud Free 1 Leak Raises Identity Theft Risk

Every record in this file is a ready-to-use set of credentials: an email, its password, and the exact site it unlocks. That combination lets an attacker skip the guesswork entirely and log straight into an account, whether it is email, a retail account, or something more sensitive. From there, personal details can be harvested to open new accounts or lines of credit in someone else's name.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs for the accounts each login belongs to

Why This Matters

Stolen login pairs like these feed directly into credential stuffing attacks, where automated tools try the same email and password across dozens of other websites. Anyone in this 11,242-record file who reused a password elsewhere is at heightened risk of account takeover, financial fraud, and identity theft.

How Stealer Logs Like Winter Cloud Free 1 Are Built

This kind of data comes from info-stealer malware, software that infects a device through a bad download or phishing link and then quietly copies saved browser passwords before sending them to whoever controls it. The stolen credentials are packaged into a "log" and shared or sold on Telegram, which is how a 2023 infection ends up circulating publicly years later.

Check If You Are Affected

Rather than searching for this one file yourself, use HEROIC's free breach scanner. It checks your email against more than 400 billion breached records, including stealer logs like this one, and shows you immediately which passwords you need to change.
