SunCloudNew 1326 Stealer Log Exposed 62,345 US Accounts on Telegram

In November 2025, HEROIC analysts identified a stealer log file circulating on Telegram that exposed 62,345 records belonging to users primarily based in the United States. The dataset, uploaded by an anonymous Telegram user and tracked internally as SunCloudNew 1326, contained plaintext email addresses, plaintext passwords, and associated URLs -- giving whoever downloaded it an immediate, ready-to-use set of login credentials scraped from infected machines.

Why This Is Dangerous

Unlike a hacked database where passwords might be hashed, stealer logs contain credentials exactly as the victim typed them. There is no cracking required. An attacker who downloads this file can open it in a text editor and immediately see someone's email address paired with the exact password they use on a given website. Because most people reuse the same password across multiple accounts, a single entry in this file can unlock email inboxes, banking portals, cloud storage, and social media profiles. The URLs included in the data make it even worse -- they tell the attacker exactly which sites to target first.

What Was Exposed in the SunCloudNew 1326 Stealer Log

• Email addresses (62,345 unique entries)
• Plaintext passwords -- no hashing, no encoding, completely readable
• URLs pointing to the exact websites where the credentials were used

Why This Matters for Affected Users

Stealer log credentials are among the most actionable data on the dark web. Criminal groups use them for credential stuffing -- running automated tools that try each email and password combination accross hundreds of popular websites at once. If your credentials appear in this log, attackers may have already attempted to access your accounts on banking platforms, email providers, and e-commerce sites. Account takeover can lead to fraudulent purchases, drained savings, and stolen personal information that fuels identity theft for years. The fact that this data circulated on Telegram means it was accessible to thousands of bad actors, not just one.

How Stealer Logs Harvest Credentials From Your Device

A stealer log is generated by a type of malware called an infostealer. These programs are typcially delivered through phishing emails, malicious software downloads, or fake browser extensions. Once installed on a victim's computer, the malware silently scans the device for saved passwords stored in browsers like Chrome and Firefox, active session cookies, and credentials entered into login forms. It packages everything it finds into a structured log file and sends that file back to the attacker's server -- or, as in this case, directly to a Telegram channel where it can be distributed instantly to anyone who follows the group. Victims rarely know their credentials have been stolen until fraudulent activity appears on their accounts.
