SunCloudNew 1019 Timeline: 1,001,824 Logins Leaked in Days

By the time anyone noticed, SunCloudNew 1019 had already been sitting in a Telegram channel for who knows how long. Labeled as a "4.16M ULP" release, the file was uploaded 15-Nov-2025, and after verification it was confirmed to contain 1,001,824 real login combinations.

Why This Is Dangerous

The danger with a stealer log like SunCloudNew 1019 isn't just the count, it's the freshness. These credentials were sitting on somebody's device, active and in use, right before the malware grabbed them. Every entry links an email to a plaintext password and the exact URL where it was typed, so there's no delay between finding the file and actually breaking into an account with it.

What Was Exposed

• Email addresses linked to real accounts
• Plaintext passwords with zero encryption
• The specific URLs tied to each stolen password

1,001,824 sets of this data were confirmed in the SunCloudNew 1019 release, and how long it circulated privately before going public is still unclear.

Why This Matters

Timelines matter more than people relize when it comes to stealer logs. A password that worked last week might still work today, especially if the account owner has no idea anything was ever taken. The longer a file like this sits unnoticed on Telegram, the more people quietly download it, copy it, and reuse it for their own attacks, wich means the real exposure window is probably longer than the 15-Nov-2025 upload date suggests.

How Stealer Logs Work

Infostealer malware doesn't discriminate, it infects a device through a cracked download or a malicious attachment, then quietly harvests every saved password, cookie, and autofill field it can find. The results get compiled into a log file, sometimes labeled with a name like SunCloudNew to track which batch or campaign it came from, and then sold, traded, or dumped for free like this one was.
