SunCloudNew Leak: 616,699 Records – Check If You’re Affected

HEROIC analysts identified a stealer log dump named SunCloudNew 1347 - 875 K ULP on Telegram, dated November 30, 2025. Once processed, the file held 616,699 records, each pairing an email address with a plaintext password and the login URL where the credentials were used.

Why the SunCloudNew Leak Is Dangerous

Because the passwords in this file are stored in plaintext, there is no cracking step for an attacker to work through. Anyone who gets a copy of this file can read the credentials directly and start testing them right away on email, banking, and shopping accounts.

What Was Exposed in the SunCloudNew Leak

• Email addresses
• Plaintext passwords
• Login URLs tied to each account

Why This Matters If You Reuse Passwords

Reusing the same password across multiple sites is common, and it is exactly what attackers count on. Once credentials from a leak like this are loaded into automated tools, criminals test them against hundreds of other services in a process known as credential stuffing.

A single successful match can open the door to account takeover, identity theft, and financial fraud, often within days of a file like this circulating online.

How Stealer Log Dumps Like SunCloudNew Get Built

Infostealer malware spreads through cracked programs, pirated media, and malicious links, then quietly harvests saved logins and cookies from an infected browser. Sellers group these logs into batches and label them with names like SunCloudNew, along with a version number to track each new release.

A file reaching 616,699 records typically means data was pulled from thousands of seperate infected devices before being cleaned up and posted for sale.
