Winter Cloud Free 2 Logs Quietly Surfaced: 13,877 Passwords

HEROIC analysts identified a stealer log named "Winter Cloud Free 2" that had been quietly circulating among Telegram users. The file, dated to August 2023, contains 13,877 records of email addresses, plaintext passwords, and the URLs of the accounts they open.

Why the Winter Cloud Free 2 Log Is Dangerous

This is not a typical database breach where a single company loses control of its user table. A stealer log like this one is assembled from malware that ran silently on infected computers, copying every saved password out of the browser. Because the passwords are stored in plaintext, whoever has the file can log in immediately, no cracking required.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the accounts each login unlocks

Why This Matters

With 13,877 ready-to-use login pairs in circulation, attackers do not need to guess or brute-force anything. If a password in this file matches one used elsewhere, credential stuffing scripts can test it against banking, email, and shopping sites within minutes, opening the door to account takeover, financial fraud, and identity theft.

How a Stealer Log Like This Gets Made

Info-stealing malware usually reaches a device through a pirated download, a fake update, or a phishing link. Once installed, it quietly harvests saved browser passwords and sends them back to whoever controls it. Those results get bundled into a "log" and traded or given away on Telegram channels, which is how the Winter Cloud Free 2 file ended up public years after it was first collected.

Check If You Are Affected

You do not need to track down this exact file to know where you stand. HEROIC's free breach scanner checks your email against more than 400 billion breached records, including stealer logs like this one, so you can find out quickly if your credentials are exposed and which passwords need to change.
