What the TXT Cloud LOGS_900PCS Telegram Breach Means for 20,741 Affected Users

In November 2025, a Telegram user uploaded a stealer log collection labeled "LOGS_900PCS" to a public channel, exposing 20,741 records tied to compromised endpoints across the United States. The data surfaced almost immediately after the apparent infection window, meaning the credentials were still fresh and highly usable. Anyone whose email and password appeared in this dataset should act quickly, since the gap between upload and exploitation tends to be narrow with Telegram-distributed logs.

Why This Is Dangerous

The TXT Cloud LOGS_900PCS dataset is dangerous because it bundles email addresses with plaintext passwords in a single file. There's no cracking step required for attackers, the credentials are ready to plug into automated login tools right away. This makes the data immediately usable for account takeover attempts across banking, social media, and workplace platforms.

The inclusion of URLs in this dataset is also a red flag. These URLs likely represent sites or services the victims were actively logged into when the malware ran, which means attackers know exactly which platforms to target first. That kind of contextual information makes this a more targeted resource than a raw credential dump.

Because the log was uploaded in late 2025, much of the data is likely to still be valid. People don't change passwords frequently, and accounts that haven't triggered a breach alert are even less likely to have been secured in the meantime.

What Was Exposed

• Email addresses
• Plaintext passwords
• Website and application URLs
• API host endpoints
• Browser-saved login credentials
• Usernames associated with compromised accounts
• Potentially active session data from infected endpoints

Why This Matters

With 20,741 records in circulation on Telegram, this dataset will inevitably reach multiple threat actors. The platform's ease of sharing means a file uploaded once can be downloaded, redistributed, and repurposed indefinitely. By the time most affected users find out, the data has already been tested against dozens of login portals.

Password reuse is the most critical amplifying factor here. A single compromised credential from one infected device could unlock email accounts, cloud storage, workplace tools, and financial platforms all at once. That's why this type of stealer log often causes far more downstream damage than the initial record count would suggest.

How Stealer Log Works

Stealer log malware is typically installed through phishing links, fake software downloads, or malicious browser extensions. Once it executes on a device, it scans for stored credentials in browsers, autofill databases, and locally cached login sessions. Everything it finds is packaged into a structured log file and sent back to the attacker's server.

The attacker then organizes these logs, often by country or credential type, and either uses them directly or sells them on underground forums. Occured in batch format, these logs are especially appealing because they can be sorted and filtered by domain, making it easy to extract credentials for specific high-value targets like corporate VPNs or payment platforms.

What makes TXT Cloud-style distributions particularly notable is the speed of release. The logs are often uploaded to Telegram within days or even hours of exfiltration, giving defenders very little time to respond before the data is being actively exploited.
