SunCloudNew 1806, 689K ULP Leaked 568,399 Plaintext Passwords

If your email is inside the SunCloudNew 1806, 689K ULP file, it means your password is sitting in a plaintext record that anyone with the file can read. HEROIC analysts counted 568,399 records in the file, uploaded to Telegram on 27-Aug-2026, each including an email, a password, and a URL. For the person behind that record, the account is exposed right now, not at some future point. The only way to know if you're affected is to scan your email.

Why Plaintext Passwords Skip the Hard Part

Normally an attacker has to crack or decrypt a stolen password before it becomes usable, which takes time and resources. Every password in this file skips that step entirely, since it is stored as plain, readable text. That means there is no delay between the leak and someone trying it on the listed URL.

What Was Packed Into This SunCloudNew File

• Email Addresses: Confirms which inbox each login belongs to and lets attackers send convincing, targeted phishing emails.
• Plaintext Password: Readable the instant the file is opened, so it can be used to log in without any cracking effort.
• URLs: Tells an attacker exactly which site or service the email and password work on, so they can go straight there.

What This Means If Your Login Is Inside

Practically, it means whoever has this file can attempt to log into your account today, using the exact URL listed next to your email and password. If that password was reused elsewhere, the same attempt can be made on other sites too. The exposure is immediate, not dependent on any further action by an attacker.

How a File of This Size Gets Assembled

A file with hundreds of thousands of records is usually built by gathering login pairs from many earlier, often older, sources and testing which ones still work. It is not evidence that one company's systems were broken into, but that these particular pairs still function somewhere online. That distinction matters for understanding what actually happened here.

Responding to the SunCloudNew 1806 Leak

Start with the scan above to check whether your email shows up in this file. If it does, change the password on that account immediately, and update it anywhere else the same password was used, since reuse is exactly what a file like this is built to exploit. This applies to work accounts just as much as personal ones.
