The SunCloudNew 1713 Leak: 16,171 Passwords Exposed. Yours Might Be One.

In April 2026, a stealer log file containning 16,171 records was uploaded to Telegram by an anonymous threat actor. The leaked data included plaintext passwords, email addresses, and URLs -- the kind of combination that gives cybercriminals everything they need to take over accounts instantly. If you use any of the services captured in this log, your credentials may already be circulating on the dark web.

Why This Is Dangerous

Stealer logs are among the most actionable types of leaked data. Unlike older database dumps, stealer logs are harvested in real time from infected devices using malware. That means the passwords captured are not just old or reused -- they are the passwords people were actively using at the time of infection. When combined with email addresses and the URLs of the services targeted, attackers have a ready-made credential kit for account takeover attacks. Plaintext passwords require zero cracking effort, and automated tools can test them across hundreads of popular services within minutes.

What Was Exposed

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

Why This Matters

The exposure of plaintext passwords alongside corresponding email addresses and service URLs creates a perfect storm for credential stuffing attacks. Threat actors who obtain this data can immediately attempt to log in to banking, email, social media, and corporate accounts. Because many people reuse passwords across multiple services, a single compromised credential can cascade into a full account takeover across your entire digital life. The fact that this data was shared on Telegram -- a platform widely used by cybercriminals -- means distribution was rapid and broad.

How Stealer Logs Work

Stealer log breaches originate from infostealer malware installed on a victim's device, often through phishing emails, malicious downloads, or compromised software. Once installed, the malware silently records browser-saved passwords, session cookies, and autofill data -- then transmits everything to the attacker. The resulting files, known as stealer logs or log files, are then sold or distributed on dark web forums and encrypted messaging platforms like Telegram. Each log file represents real credentials from real people who had no idea their device was compromised.
