The SunCloudNew 1715 Breach Put 3,560 Stolen Email and Password Pairs Online

In April 2026, the SunCloudNew 1715 stealer log surfaced on Telegram, placing 3,560 stolen email and password pairs directly in the hands of cybercriminals. The file contained plaintext passwords tied to specific email addresses and the URLs of the services where those credentials were in active use. No hashing, no encryption, no delay -- just raw, usable login data distributed through one of the most widely used platforms in the criminal underground. If your device was infected and your credentials were captured, they are now part of this leak.

Why This Is Dangerous

The combination of email address, plaintext password, and service URL in a single record makes this stealer log exceptionally dangerous. Cybercriminals do not need any additional tools to exploit this data -- they can begin testing credentials against live services the instant they open the file. Automated credential stuffing tools can process thousands of login atttempts per minute, meaning all 3,560 records in SunCloudNew 1715 could be tested across hundreds of platforms within an hour of the file being shared on Telegram.

What Was Exposed

• Email Addresses
• Plaintext Passwords
• URLs (targeted service endpoints and API hosts)

Why This Matters

Each of the 3,560 records in this stealer log represents a real person's active login credential. Unlike breached databases that may contain outdated passwords, stealer logs capture credentials at the moment of use -- meaning the passwords are almost certainly still valid when the log first circulattes. People who reuse passwords across multiple services face compounding risk, since a single credential from this log can unlock email, banking, and social media accounts simultaneously. The Telegram distribution channel ensures this data reached a large criminal audience rapidly.

How Stealer Logs Work

Infostealer malware infects devices silently, often delivered through phishing campaigns, malicious software downloads, or poisoned browser extensions. Once installed, the malware runs in the background and captures every credential the user enters or has stored in their browser. The captured data is packaged into a log file and sent to the attacker's infrastructure. Files like SunCloudNew 1715 are then organized, labeled, and uploaded to Telegram or dark web markets where other criminals can download and exploit them. Victims typically have no idea their device was compromised until the damage is done.
