InfernoLogsCloud LOGS FREE183 uploaded by a Telegram User

We've been tracking a steady increase in stealer logs surfacing on Telegram channels, a trend that's becoming a significant source of exposed credentials. This particular incident caught our attention not because of its size, but due to the sensitive nature of the exposed data and the clear indication of compromised systems within what appears to be a development or testing environment. The data had been circulating quietly, but we noticed the file name and structure suggested a targeted collection effort, rather than a broad, indiscriminate sweep. This raises concerns about the potential for attackers to leverage these credentials for further access into internal systems.

InfernoLogsCloud Stealer Log Exposes Sensitive Credentials

In August 2025, a Telegram user uploaded a stealer log file named InfernoLogsCloud LOGS FREE183. What really struck us wasn't the volume of records—4,583—but the type of data included. The log contained a mix of email addresses, plaintext passwords, and URLs, all seemingly related to internal systems. The plaintext passwords are particularly alarming, as modern security practices strongly discourage storing passwords in this format. The presence of URLs alongside credentials suggests the attacker may have been targeting specific internal applications or APIs.

The breach was discovered on August 7, 2025, when the file was uploaded to a public Telegram channel. The file quickly gained traction within the channel, raising concerns among security researchers monitoring these platforms. We believe it caught attention because it offered a relatively complete snapshot of credentials and endpoints, making it valuable for attackers seeking to move laterally within a network. The data’s structure—a typical stealer log format—suggests it was likely harvested using commodity malware designed to extract credentials from infected systems.

This breach matters to enterprises now because it highlights the ongoing risk posed by stealer logs and the potential for even relatively small leaks to expose critical internal systems. The fact that credentials were stored in plaintext underscores the need for robust security practices, including strong password policies and multi-factor authentication. The incident also underscores the growing trend of attackers using Telegram and other social media platforms to share and monetize stolen data.

• Total records exposed: 4,583
• Types of data included: Email Addresses, Plaintext Passwords, URLs
• Sensitive content types: Credentials, potentially internal system addresses.
• Source structure: Stealer log file
• Leak location: Telegram
• Date of first appearance: 07-Aug-2025

External Context & Supporting Evidence

The use of Telegram as a distribution point for stolen data is well-documented. Security researchers have observed a growing trend of threat actors using Telegram channels to buy, sell, and share stealer logs and other compromised data. This trend is further fueled by the relative anonymity and ease of use offered by the platform. One Telegram post, observed by our team, claimed that similar stealer logs were being "sold to access corporate VPNs," highlighting the direct financial incentive driving this activity.

While specific news coverage of this incident is not yet available, numerous reports from outlets like BleepingComputer and The Record have highlighted the broader threat posed by stealer logs and the increasing sophistication of malware used to harvest credentials. These reports emphasize the need for organizations to proactively monitor for compromised credentials and implement robust security measures to prevent malware infections.
