SunCloudNew LogsFile Telegram Breach: 10,286 Records Quietly Exposed

In December 2025, HEROIC discovered a stealer log file shared on Telegram under the label "SunCloudNew 1348 - 450 LogsFile," exposing 10,286 records. Distributed anonymously through Telegram, the file contained plaintext passwords, email addresses, and URLs captured from compromised devices by infostealer malware. The SunCloud naming convention is associated with a series of log distribution packages circulated through Telegram channels in late 2025.

Ten thousand compromised accounts is not a small number. Each record represents a real person whose device was infected, whose login credentials were silently copied, and whose accounts are now accessible to anyone who downloaded this file. The data is recent, it's plaintext, and it includes the exact URLs where each victim was logged in — giving attackers a precise roadmap to the accounts they want to hit.

What SunCloudNew 1348 - 450 LogsFile uploaded by a Telegram User Leaked: The Full Data Picture

• Email Addresses — victim identifiers that connect each person to every account they own online
• Plaintext Passwords — unencrypted credentials that require no cracking and are ready to use immediately
• URLs — the actual login pages captured by the malware, showing attackers which platforms each victim uses

Why SunCloudNew 1348 - 450 LogsFile uploaded by a Telegram User Data Creates Lasting Identity Risk

This breach may not have made headlines, but that doesn't mean the risk is small. Here is what victims face:

Credential stuffing attacks quietly work through your stolen credentials across dozens of platforms. The attacks are automated and persistent — bots keep testing until they find accounts that haven't been secured. Many victims don't realise they've been compromised until weeks later.

Password reuse silently multiplies the damage. A password used on a less critical service that ended up in this breach can unlock email inboxes, banking portals, and cloud accounts. The attacker doesn't need to know you personally — the credential list does the work.

Phishing thrives on exact data. Knowing your email address and which specific services you use allows attackers to send messages that look completley legitimate. These aren't generic scam emails — they're targeted messages referencing the exact services you rely on.

How Stealer Log Attacks Harvest Login Data

The SunCloudNew logs, like all stealer log breaches, trace back to infostealer malware installed on victim computers. These infections typically start with a phishing email, a compromised download, or a malicious browser extension. The malware installs quietly and begins recording immediately — capturing login credentials as they're typed, extracting stored passwords from the browser, and collecting session cookies that let attackers bypass two-factor authentication.

Once the malware has collected enough data, it bundles everything into a log file and sends it to the attacker. These log files are then sold in bulk on Telegram and dark web marketplaces, or released in sample batches to advertise paid services. Victims typically have no idea this has happened. There is usually no popup, no slowdown, no warning of any kind. The infection is silent and the data is already gone before most people would ever notice anything is wrong.
