How SunCloudNew 1347 Sent 10,744 Stolen Credentials to Telegram

HEROIC analysts have verified a stealer log collection uploaded to Telegram in November 2025 under the label "SunCloudNew 1347 - 500 LogsFile" that exposed 10,744 records from infected endpoints in the United States. The batch number "1347" suggests this was part of a numbered series of ongoing releases from the SunCloudNew distribution operation, and the "500 LogsFile" designation confirms the collection contained individual log files from 500 separate infected machines. Exposed data includes email addresses, plaintext passwords, and the URLs where those credentials were captured.

The structured naming of this collection -- with sequential batch numbers and explicit log file counts -- reflects a professional, organized criminal distribution operation rather than a one-off data leak. SunCloudNew is a known Telegram channel running a regularized log distribution model, pushing numbered batches to subscribers on a recurring schedule. The 10,744 records in batch 1347 represent just one installment in what appears to be an ongoing, large-scale infostealer campaign targeting US-based internet users.

What Data the SunCloudNew 1347 500 LogsFile Breach Exposed

• Email Addresses -- Account identifiers enabling targeted attacks across any email-based login system
• Plaintext Passwords -- Cleartext credentials immediately deployable without any decryption step
• URLs -- The specific services each victim was logged into at the moment of infection
• Endpoint Metadata -- Device and network data from each of the 500 infected machines in this batch

The Path From SunCloudNew 1347 500 LogsFile Breach to Account Fraud

The numbered batch structure of SunCloudNew releases is designed for efficiency -- subscribers receive regular deliveries of fresh, organized credentials that plug directly into credential stuffing automation. With 10,744 plaintext email and password pairs, a criminal actor can run automated login attacks against dozens of major platforms simultaneously, typically within hours of receiving the batch. Password reuse across accounts means each successful credential often unlocks far more than one platform.

The URL data elevates the threat from bulk stuffing to targeted identity theft. Attackers can identify victims who were authenticated to high-value services -- tax platforms, investment portals, corporate intranets -- and specifically pursue those accounts rather than relying on random stuffing success. These targeted approaches yield higher-value compromises and are harder for victims to detect, since attackers often access accounts sparingly at first to avoid triggering security alerts before extracting what they need.

Stealer Log Attacks: A Plain-English Explainer

The SunCloudNew operation illustrates how professionalized the infostealer market has become. At the front end, malware is deployed through standard infection vectors: pirated software, fake game cracks, maliciuos browser extensions, and phishing emails. The malware runs silently after installation, harvesting saved browser passwords, session cookies, credit card autofill data, and a list of URLs the victim visited while infected.

At the back end, the collected data flows into cloud infrastructure the attacker controls -- which is likely what the "SunCloud" branding references. The cloud backend aggregates logs from hundreds or thousands of infected machines, automatically sorts and structures them, and prepares numbered batch releases for Telegram distribution. This automated pipeline means criminal operators can maintain a steady publication schedule with minimal manual effort, which is why batches like "1347" can exist -- the numbring implies thousands of previous releases from the same operation.
