SunCloudNew Leak: What Hackers Can Do With 16,771 Passwords

What Hackers Can Do With the SunCloudNew Stealer Log

HEROIC analysts verified a stealer log labeled SunCloudNew, uploaded to Telegram on 10-Sep-2025, containing 16,771 records. Each entry includes an email address, a plaintext password, and the URL the credentials were captured from, giving whoever holds the file everything needed to log in as the victim.

Why the SunCloudNew Leak Is Dangerous

With plaintext passwords already matched to specific website URLs, an attacker doesn't need any technical skill to cause damage. They can simply load the SunCloudNew file into automated login tools and attempt to access every one of the 16,771 accounts represented in the log, all at once.

What Was Exposed in the SunCloudNew Log

• Email addresses
• Plaintext passwords
• URLs of the sites the credentials were used on

Why This Matters for Your Other Accounts

Attackers rarely stop at the account listed in the log. Once they have a working email and password combination, they run it against banking sites, email providers, and shopping accounts through credential stuffing, hoping the same password was reused. That single reused login is often all it takes for account takeover, identity theft, or financial fraud.

How a Stealer Log Like SunCloudNew Gets Created

Info-stealing malware infects a device, then quietly extracts saved browser passwords, autofill data, and visited URLs without the user noticing. The results get bundled into a file, in this case labeled as part of a larger batch numbered in the thousands, and distributed through Telegram channels where buyers and sellers trade stolen data.
