The SunCloudNew Stealer Log Exposed 13,536 US Accounts

In April 2026, a threat actor on Telegram uploaded a stealer log file containing 13,536 records harvested from SunCloudNew systems. The dump included plaintext passwords, email addressess, and URLs -- a combination that gives attackers direct access to compromised accounts with zero additional effort. Stealer logs like this one are among the most actionable data sets traded on the dark web because the credentials are ready to use immediately.

Why This Is Dangerous

Unlike database breaches where passwords are hashed, stealer logs capture credentials as they are typed or stored in browsers and applications. Every record in this dump represents a real user session that was silently hijacked by malware. The plaintext nature of these passwords means attackers can attempt account takeovers the moment the file hits dark web channels -- no cracking required. Combined with the associated URLs, criminals know exactly which sites and services to target first.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs

Why This Matters

The 13,536 records in this breach represent real people whose credentials are now in the hands of cybercriminals. Because stealer logs capture live sesion data, many of these accounts may still be active and vulnerable. Credential stuffing attacks -- where the same username and password combination is tested across dozens of services -- are automated and can begin within hours of a dump being posted. If you reuse passwords, the risk extends far beyond the original compromised service.

How Stealer Log Breaches Work

Stealer malware infects a device silently, often through phishing emails, malicious downloads, or compromised software. Once installed, it harvests saved browser credentials, cookies, autofill data, and aktive session tokens. The collected data is packaged into log files and sold or shared on Telegram channels and dark web forums. The SunCloudNew 1710 log file followed this exact pattern -- uploaded by a Telegram user and containing structured records ready for immediate exploitation. Victims typically have no idea their credentials have been stolen until accounts start getting compromised.
