SunCloudNew 1767 Leak Exposed 248K US Emails and Passwords

HEROIC analysts identified a new stealer log dump on July 1, 2026, circulating under the name SunCloudNew 1767 after being uploaded by a user on Telegram. The file contained 248,681 records pulled straight from infected computers, including email addresses, plaintext passwords, and the exact website URLs each login belongs to. Because the credentials sit in plaintext, an attacker does not need to crack or decrypt anything. They can copy, paste, and log in immediately.

Why the SunCloudNew 1767 Leak Is Dangerous

What makes this dump particularly nasty is the pairing of email, password, and URL. Most breaches give an attacker a username and a scrambled password hash that still has to be cracked. This one hands over a ready made login kit for hundreds of thousands of accounts, already matched to the exact site each victim uses. A criminal could recieve this file and start testing logins against banking portals, email providers, and shopping accounts within minutes, with no technical skill required.

What Was Exposed in the SunCloudNew 1767 Dump

• Email addresses tied to real user accounts
• Plaintext passwords, stored and leaked with no encryption
• Login URLs showing exactly which site or service each credential unlocks

In total, 248,681 unique records were confirmed inside the file, most of them belonging to users based in the United States.

Why This Matters for Everyday Users

A leak like this rarely stays contained to one account. Most people reuse the same password across multiple sites, so a password stolen from one browser can unlock email, banking, and social media accounts belonging to the same person. This is exactly how credential stuffing attacks happen: automated tools take leaked email and password pairs and quietly try them against hundreds of other websites until one works. From there, account takeover, identity theft, and outright financial fraud all become alot easier for the attacker and alot harder to undo for the victim.

How a Stealer Log Dump Like This Gets Created

Stealer logs come from infostealer malware, a type of program quietly installed on a victim's device through a fake download, cracked software, or a malicious email attachment. Once running, it scans the browser for saved passwords, autofill data, and session cookies, then bundles everything into a single file and sends it back to whoever controls the malware. Criminals often trade or dump these files, sometimes labeled as ULP (a shorthand for URL, login, password) collections, on Telegram channels and dark web forums like the one seen with SunCloudNew 1767. The victim usually has no idea their machine was ever infected, since the malware does not lock files or demand a ransom. It just quietly harvests and leaves.
