HEROIC Analysts Discover 1,723,278-Record SunCloudNew Leak

While tracking new stealer log activity across Telegram, HEROIC analysts came across a file called "SunCloudNew 1217 14," uploaded in late May 2026. After reviewing it, the count came out to 1,723,278 individual records, each one a leaked email and password pair sitting in a channel that anyone could join and download from.

Why This Is Dangerous

Discoveries like this matter because most people never hear about leaks unless a major brand name is attached to them. A generic file name like SunCloudNew doesn't make headlines, wich means it can circulate for a long time before regular internet users even realize their information might be inside. That quiet spread is often more dangerous than a splashy, well-known breach.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs for each account
• 1,723,278 total records

Why This Matters

Every record in this leak includes a seperate URL showing which site the credential unlocks, so it's not just a random pile of passwords, it's an organized list ready to be tested. That level of detail makes stolen data far more usable, and far more dangerous, than a plain list of passwords alone would be.

How Stealer Logs Work

This file falls under the "stealer log" category, meaning it originated from information-stealing malware running on infected machines rather than a single company database breach. The malware scrapes browser-saved logins and autofill entries, then exports them for the attacker. Analysts frequently find these logs bundled and reposted on Telegram under names like SunCloudNew, often numbered sequentially as new batches appear.
