The SunCloudNew 1706 Dump Contains Exactly 530,321 Email and Password Pairs

HEROIC analysts identified the SunCloudNew 1706 stealer log while monitoring private Telegram channels in April 2026. The file, advertised as containing 577K records, was found to hold 530,321 confirmed entries after processing. Each entry contained an email address, a plaintext password, and the URL of the site where the credential was originally used. Files like this one are typical of organized stealer log operations where threat actors compile and distribute harvested login data in bulk.

Why Half a Million Unencrypted Credentials Represent an Immediate Threat

Plaintext passwords require no additional processing before use. An attacker with this file can load it directly into an automated credential stuffing tool and begin testing logins within minutes. The URLs included in each record make the attack even more efficient, because they tell the attacker exactly which service the password belongs to. Someone whose credentials appear in this file may already be at risk of having their accounts accessed without their knowledge.

What the SunCloudNew 1706 ULP Dump Exposed

• Email addresses used as login identifiers
• Plaintext passwords with no hashing or obfuscation
• URLs pointing to the specific services where each credential was active

Why the SunCloudNew Scale Makes Credential Stuffing and Account Takeover Far More Likely

With over half a million records in a single file, this dump gives attackers a large pool of working credentials to cycle through. Even if a fraction of the passwords are still valid, that represents tens of thousands of accounts that can be taken over. Credential stuffing attacks use this kind of volume deliberately: the more records available, the higher the chance of finding accounts where the password has not yet been changed or where the same password is reused across multiple services. Victims whose data is comprimised in a file like this frequently find out only after their bank account is drained, their email is used to send spam, or their identity has been used to open new credit lines.

Password reuse is the biggest risk factor here. If the email and password in this file match credentials used anywhere else, every one of those accounts is at risk.

How Stealer Logs Like SunCloudNew 1706 Are Assembled and Sold

ULP files are the output of information-stealing malware running on real devices. The malware, often disguised as a software crack, game mod, or browser extension, installs itself silently and begins extracting saved passwords from browsers like Chrome and Firefox. It also captures session cookies, which can allow access to accounts even without knowing the password. The harvested data is formated into structured text files using the URL:Login:Password layout, which is why these files are called ULP logs. They are then uploaded to Telegram channels or dark web markets where other criminals purchase or download them. The SunCloudNew channel name suggests this was part of an ongoing operation distributing fresh logs on a regular basis.
