How a Telegram Upload Leaked 987,074 SunCloud Login Records

The file was labeled "SunCloudNew 1014 - 3.68 M ULP" when it hit Telegram, though once HEROIC researchers verified the contents the real number came to 987,074 usable login records. Understanding how a file like this comes together says a lot about why it is worth paying attention to.

Why This Is Dangerous

Unlike a breach where a company's server gets broken into, this data was harvested one device at a time. Malware sitting on infected computers quietly grabbed saved passwords, autofill data, and the sites they belonged to, then funneled everything back to whoever controls the SunCloud operation untill enough logins piled up to package and post.

What Was Exposed

• 987,074 total records
• Email Addresses
• Plaintext Passwords
• URLs tied to each account

Why This Matters

Every record in this file recieve its data directly from a real, active login session, which means the passwords are current rather than outdated leftovers from an old breach. That makes them far more useful to criminals than an old database dump where half the passwords have already been changed.

How Stealer Logs Work

Step one, malware infects a device, often through a cracked download or phishing link. Step two, it silently scrapes browser-saved credentials, cookies, and autofill fields. Step three, everything gets bundled into a text log and uploaded, in this case to a Telegram channel trading under the SunCloud name, where buyers and curious onlookers alike can grab it.

Check If You Are Affected

Instead of wondering whether your login sits inside this file, use HEROIC's free breach scanner to check your email against a database of over 400 billion exposed records and see your real exposure in seconds.
