SunCloudNew Leak Exposed 1,473,045 Login Records in May 2026

The SunCloudNew stealer log exposed 1,473,045 login records in May 2026. That is the whole story in one sentence, but the details underneath it are worth understanding.

Why This Is Dangerous

A leak of this size, over 1.4 million records, isn't a small local combolist, it's a large-scale credential dump that imediately puts a huge number of people at risk the moment it starts circulating. The bigger the file, the more attackers download and reuse it.

What Was Exposed

• 1,473,045 total records
• Email Addresses
• Plaintext Password
• URLs

Why This Matters

With over a million plaintext passwords in circulation, automated tools can test thier way through logins far faster than any human could, checking each email and password pair against popular websites within minutes of the file being downloaded. Scale is what makes this leak definately worth paying extra attention to.

How Stealer Logs Work

Large stealer logs like this one are usually the result of a widespread malware campaign rather than a single infected device. Thousands of separate infections get compiled together over time, and once the total reaches a certain size, the whole batch gets released or sold as one file.
