SunCloudNew Stealer Log: 7,693 Passwords Leaked in Plaintext

HEROIC analysts identified a stealer log file called SunCloudNew 1336 - 500 LogsFile, uploaded to a public Telegram channel on November 18, 2025. The file contained 7,693 exposed records, including email addresses, plaintext passwords, and the URLs of the accounts those credentials belong to, all harvested directly from infected devices.

Why This Is Dangerous

Because the passwords are stored in plaintext and matched to the exact login URL, this data is ready to use the moment someone downloads it. There is no cracking or decrypting required, just a list of working logins.

What Was Exposed

• Email addresses
• Plaintext passwords
• URLs of the associated login pages and accounts

Why This Matters

Anyone who reused one of these passwords elsewhere is at risk of credential stuffing attacks and account takeover. The paired email addresses also make the data useful for identity theft and financial fraud attempts against victims who may have no idea their information is exposed.

How Stealer Log Breaches Happen

Stealer logs like SunCloudNew 1336 come from infostealer malware that infects a device through a phishing link, cracked software, or a fake installer. Once active, it scans the browser for saved logins and autofill data, then packages everything into a log tied to that machine. Criminals collect thousands of these logs and upload or sell them in bulk, which is how this dataset reached the public.
