InfernoLogs LOGS FREE169 uploaded by a Telegram User

We've been tracking a steady increase in stealer log dumps appearing on Telegram channels, but the InfernoLogs LOGS FREE169 file caught our attention due to its relatively recent compilation date (May 9, 2025) and the inclusion of not just credentials, but also API hosts. This suggests a focus on potentially compromising development environments or automated processes rather than just individual user accounts. The data had been circulating quietly within a specific Telegram group before we identified it. What really struck us wasn't the volume of records exposed – 15,333 – but the potential for lateral movement within compromised organizations given the presence of API endpoints.

InfernoLogs: Stealer Log Exposes 15,333 Credentials and API Hosts

This breach stems from a stealer log file, dubbed InfernoLogs LOGS FREE169, uploaded to a Telegram channel on May 9, 2025. These logs are typically the result of malware infections that harvest data from infected machines, including usernames, passwords, cookies, and autofill data. What made this particular log noteworthy was the explicit inclusion of API host information alongside more standard credential dumps. This suggests the compromised machines may have been used for development, testing, or automation purposes, potentially providing attackers with access to sensitive internal systems.

The discovery occurred during our routine monitoring of Telegram channels known to traffic in stolen credentials and data dumps. The file's name and the channel's activity history initially flagged it for review. Its contents confirmed the presence of a significant number of email addresses, plaintext passwords, and URLs, along with the aforementioned API host details. This matters to enterprises because it highlights the ongoing risk posed by stealer malware, and the potential for attackers to leverage stolen credentials to gain access to critical infrastructure beyond individual user accounts. The inclusion of API host information dramatically increases the potential blast radius of a successful compromise.

• Total records exposed: 15,333
• Types of data included: Email Addresses, Plaintext Passwords, URLs, API Hosts
• Sensitive content types: Credentials, potentially sensitive internal URLs and API endpoints
• Source structure: Stealer log file (format unspecified, but likely a text-based dump)
• Leak location(s): Telegram channel
• Date of first appearance: May 9, 2025

External Context & Supporting Evidence

The use of Telegram channels for the distribution of stealer logs is a well-documented trend. Cybercrime researchers have observed a surge in such activity, with various groups and individuals using these channels to share or sell compromised data. BleepingComputer has reported extensively on the rise of stealer malware and the subsequent dumping of logs on various platforms, including Telegram. These reports often highlight the speed at which stolen data can be disseminated and the challenges in tracking and mitigating the risks associated with these leaks.

While specific chatter related to the InfernoLogs LOGS FREE169 file is limited, the broader discussion surrounding stealer logs on Telegram is extensive. One Telegram post we observed, unrelated to this specific leak but representative of the trend, claimed that "fresh logs with API keys are selling fast, get yours before they're useless." This underscores the perceived value of such data within the cybercriminal community and the speed at which attackers attempt to monetize stolen information. The risks associated with this type of breach are compounded by the fact that many organizations still struggle with basic password hygiene, leaving them vulnerable to credential stuffing attacks even when plaintext passwords are leaked.
