Sun Cloud Mix 4-12 Exposed 11,023 US Passwords. Has Yours Changed?

In December 2022, a stealer log identified as "Sun Cloud Mix 4-12" was uploaded to Telegram, exposing 11,023 email addresses and plaintext passwords from US devices. That was more than three years ago. For anyone in this log who has not changed their password since December 2022, those credentials remain just as valid today as when the log was first posted. Stolen credentials do not expire on their own. They stay active until the account holder changes the password.

Why a 2022 Stealer Log Is Still Dangerous in 2026

Many victims of stealer log breaches never discover their exposure. Of those who do, many do not identify every affected account or change every password across every service where they reused that credential. This means that a log uploaded in December 2022 can continue to produce successful account takeovers years later. Credential stuffing campaigns frequently revisit older logs precisely because the attack surface persists long after the original upload. Older logs are also cheaper to acquire on dark web markets, making them attractive to less sophisticated actors who cycle through bulk credential databases looking for accounts that have not yet been secured.

What Was Exposed in the Sun Cloud Mix 4-12 Log

• Email Addresses: Login identifiers for the compromised accounts, still in active use years after the breach
• Plaintext Passwords: Unencrypted credentials that work immediately if unchanged since 2022
• URLs: The specific services each victim was using at the time of infection

Why This Matters: Unchanged Passwords Keep Old Breaches Active

The 11,023 people in this log have had over three years of exposure. During that time, the Sun Cloud Mix 4-12 credentials have been available to anyone who downloaded the Telegram upload, passed through dark web markets, or incorporated the log into credential stuffing toolkits. If any of those people are still using the same password today, their accounts remain at risk from a breach that happened in 2022. Checking for exposure and changing affected passwords is the only way to close that window.

How the Sun Cloud Mix 4-12 Log Was Created

Stealer malware delivers itself through phishing links, malicious downloads, fake software cracks, and compromised browser extensions. Once installed, it quietly harvests browser-saved passwords, session cookies, and active URL data, transmitting everything to an attacker's server within seconds of infection. The attacker packages the collected data into a log file and distributes it. The Sun Cloud Mix 4-12 upload represents the output of infections across US devices in late 2022, compiled and published to Telegram on December 6, 2022.
