SunCloudNew Log Leaks 1,542,373 Logins, More Than a Small City

Picture every single resident of a small city, all 1,542,373 of them, having their email and password sitting in one file on the dark web. That is the scale of the latest dump tied to the source labeled "SunCloudNew 2674 8," uploaded to Telegram as part of an ongoing stealer log series.

Why This Is Dangerous

Size alone does not make a leak dangerous, but combined with plaintext passwords it becomes a serious problem fast. There is no encryption standing between an attacker and a working login, wich means the damage from a dump this large can spread in a very noticable way across many unrelated accounts and services.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs tied to each account
• 1,542,373 total records

Why This Matters

A leak of this size doesn't stay contained to one group of people. It gets copied, reposted, and folded into other combolists, so even if you check tommorow and find nothing, the data can resurface again later under a different file name.

How Stealer Logs Work

These logs come from malware that infects a device and silently collects saved credentials from the browser. Once enough infected machines report back, the operators compile everything into one giant file, label it with a batch number like "2674 8," and post it for others to grab. Unfortunatly, the process can repeat itself many times from the same malware campaign, which is why you often see multiple dumps from a similar source name.

Check If You Are Affected

With over 1.5 million records in this single file, checking your own exposure only takes a moment. HEROIC's free breach scanner searches across more than 400 billion leaked records so you can see immediately if your email is part of this or any other dump.
