How SunCloudNew’s 508K Password Leak Ended Up on Telegram

On July 14, 2026, a Telegram user uploaded a file labeled "SunCloudNew 1777 - 535 K ULP" to a channel HEROIC analysts monitor for leaked credential dumps. Once analysts pulled and reviewed the file, it contained 508,660 records, each pairing an email address with a plaintext password and the URL the login was originally used on. "ULP" stands for "URL, Login, Password," the standard format threat actors use to package stolen credentials for resale or reuse, and this file followed that format exactly.

Why the SunCloudNew Leak Is Dangerous

The danger here comes from how directly usable the data is. Because each of the 508,660 entries already includes the destination URL alongside the email and password, an attacker does not need to research where a stolen login might work. They can load the whole file into automated credential-stuffing software and let it test every combination against its matching site within minutes. If you reused that same email and password on other accounts, those are exposed too, since criminals routinely try leaked logins across banking, email, and shopping sites hoping for a match.

What Was Exposed in the SunCloudNew File

• Email addresses
• Plaintext passwords
• URLs identifying where each login was used

Why This Matters for Anyone Whose Credentials Were Reused

With over 500,000 credential pairs now in circulation, the real risk is not just the original accounts these logins belonged to, it is every other account where the same password was reused. Attackers rely on that overlap to turn one leaked combolist into dozens of compromised accounts through credential stuffing, opening the door to financial fraud, identity theft, and account takeover on services that had nothing to do with the original leak.

How a Combolist Like This Gets Uploaded and Spread

Files like "SunCloudNew 1777 - 535 K ULP" typically start as a compilation of stolen credentials gathered from smaller breaches, phishing campaigns, or malware-infected devices. Once assembled, a user packages the file with a label describing its size and format, in this case "535 K ULP," and uploads it to a Telegram channel where other users can download it for free or in exchange for a fee. From there, the file is often copied, renamed, and reposted across other channels and forums, extending its reach well beyond the original upload.

Check If Your Email Is in This Leak

With 508,660 records now circulating from this file, checking your exposure takes seconds. HEROIC's free breach scanner searches a database of more than 400 billion compromised records, including this SunCloudNew leak, and tells you immediately if your email address was affected. If it was, change that password now, and update it anywhere else you may have reused it.
