The SunCloudNew 1746 Leak Exposed 319K United States Accounts

HEROIC analysts identified a stealer log file circulating on Telegram in June 2026 under the name SunCloudNew 1746. The archive contained 319,181 records harvested from infected devices, exposing email addresses, plaintext passwords, and the URLs of websites where those credentials were used. The file was uploaded by an anonymous Telegram user and quickly spread through private threat-sharing channels before our team catalogued it.

Why This Stealer Log Is Dangerous

Unlike an old database dump, a stealer log comes straight off a victim's device. That means the passwords inside are the ones people were actively using at the time of infection. They had not been changed, rotated, or reset. An attacker who downloads this file gets working credentials for real accounts -- email inboxes, cloud storage, banking portals, and social media -- not stale data from years ago. Because the log also includes the exact URL where each password was entered, attackers do not even have to guess which site to try. The match is already made for them.

What the SunCloudNew 1746 Log Exposed

• Email addresses (used as usernames across hundreds of services)
• Plaintext passwords (not hashed, not encrypted -- ready to use immediately)
• URLs (the exact websites where each credential was captured)

Why the SunCloudNew 1746 Leak Puts Accounts at Risk

When attackers get a matched email, password, and URL from a stealer log, the first thing they do is run those credentials against other popular sites. This techneque is called credential stuffing, and it works because most people reuse the same password in multiple places. One stolen login can unlock your primary email, which then lets an attacker reset the password to your bank, your streaming accounts, your cloud backups -- everything tied to that inbox. Identity theft and finacial fraud often start with exactly this kind of data. The 319,181 records in this log represent 319,181 potential entry points into real people's digital lives.

How Stealer Logs Like SunCloudNew 1746 Are Created

A stealer log is produced by a category of malware called an infostealer. These programs typically spread through phishing emails, cracked software downloads, fake browser extensions, or malicious ads. Once installed on a victim's machine, the infostealer silently harvests saved browser passwords, autofill data, session cookies, and the URLs of recently visited sites. It packages everything into a structured log file and sends it back to the attacker's server. The victim usually has no idea anything happened. The attacker then sorts, deduplicates, and sells or distributes these logs on Telegram channels and dark web forums. SunCloudNew 1746 is one such bundle -- collected from infected machines and released publicly on Telegram in June 2026.
