SunCloudNew Stealer Logs Quietly Expose 8,288 Passwords

In July 2026, HEROIC analysts quietly flagged a stealer log breach circulating under the name SunCloudNew, uploaded to a Telegram channel by an anonymous user. Though the file's own label suggested around 500 entries, verification of the actual contents found 8,288 records, including email addresses, plaintext passwords, and the URLs of the sites each login belongs to.

Why the SunCloudNew Leak Is Dangerous

There was no announcement, no press release, just a file quietly passed around a Telegram channel containing thousands of usable logins. Because every password was stored and shared in plaintext, anyone who downloads the file can use the credentials immediately, with no cracking required. Each record also lists the exact website URL a login belongs to, giving attackers a direct map of which account each stolen password unlocks.

What Data Was Exposed in the SunCloudNew Breach

• Email addresses
• Plaintext passwords
• Associated login URLs

Why This Matters

Quiet leaks like SunCloudNew often do more damage than loud, headline-grabbing breaches because victims never hear about them. The data still gets fed into credential stuffing tools that test the same email and password pair across banking sites, email providers, and social platforms. Since so many people reuse passwords, a single exposed login from this file can quickly turn into account takeover, financial fraud, or identity theft.

How Stealer Log Breaches Work

Stealer logs are produced by malware that silently infects a victim's device and harvests saved passwords, autofill data, and login details straight out of the browser. That information, complete with the site URL tied to each credential, is bundled into a single file and traded quietly through channels like Telegram, exactly how the SunCloudNew data ended up circulating.
