LogsDiller Cloud_Free_10 uploaded by a Telegram User

We noticed an unusual surge in traffic originating from a previously unmonitored cloud storage service on December 8th, 2025. Upon investigation, it became apparent that a file, identified as "LogsDiller Cloud_Free_10," had been uploaded by an anonymous Telegram user. What struck us was the immediate and unencrypted nature of the credentials within this log file, suggesting a rapid and potentially automated exfiltration process. The sheer volume of exposed credentials, while not astronomical, represents a significant risk given the direct access they could provide to connected services.

The breach, categorized as a stealer log incident, originated from a compromised endpoint, likely infected with malware designed to harvest credentials. The uploaded file contained 1413 distinct records, each detailing an endpoint, an associated email address, the API host it communicated with, and crucially, plaintext passwords. This direct exposure of credentials bypasses many common security layers and presents an immediate threat of account takeover. The source structure appears to be a typical stealer log format, indicating automated collection and exfiltration. The leak location was a freely accessible cloud storage service, accessible via a direct URL shared on Telegram, highlighting the low barrier to entry for malicious actors to acquire this data.

While specific news coverage for this particular, smaller-scale leak is unlikely, the broader trend of credential stuffing attacks leveraging data from stealer logs is well-documented. Security researchers frequently publish findings on the prevalence of such data appearing on dark web forums and Telegram channels. The methodology employed here aligns with documented techniques used by various cybercriminal groups to amass credentials for subsequent exploitation, often in credential stuffing campaigns targeting popular online services.

We observed a peculiar anomaly in our network telemetry on December 8th, 2025, specifically a series of outbound connections to an obscure IP address that was not part of our approved infrastructure. Subsequent analysis revealed this traffic was associated with a data dump uploaded to a public cloud repository. What was particularly concerning was the inclusion of what appeared to be operational credentials, directly accessible within the uploaded file. The lack of any obfuscation or encryption on these sensitive details points to a significant lapse in endpoint security and data handling practices.

This incident, identified as a stealer log compromise, involved the exfiltration of 1413 records from a compromised endpoint. The leaked data types include email addresses, plaintext passwords, and associated URLs, likely representing the services those credentials granted access to. The description indicates the data was uploaded by a Telegram user, suggesting a deliberate act of sharing or selling the harvested information. The source structure is consistent with logs generated by infostealer malware, which systematically collects and transmits sensitive data. The leak location was a cloud storage service, readily accessible to anyone with the provided link, effectively turning it into an open repository for compromised credentials.

While this specific leak may not have garnered widespread media attention, the underlying threat of infostealer malware is a persistent concern. Numerous reports from cybersecurity firms detail the ongoing proliferation of such malware and the subsequent public availability of harvested credentials. The ease with which this data was disseminated via Telegram underscores the challenges in containing such breaches once data leaves the compromised environment.

Our threat intelligence platform flagged a new data aggregate on December 8th, 2025, originating from a service labeled "LogsDiller Cloud_Free_10." The metadata indicated a recent upload by a Telegram user, prompting immediate concern due to the potential for sensitive information. What stood out immediately was the inclusion of what appeared to be direct login credentials, presented in a raw, unencrypted format. This discovery suggests a critical vulnerability was exploited, leading to a rapid and unhindered data exfiltration.

The breach, classified as a stealer log incident, resulted in the exposure of 1413 records. The leaked data includes email addresses, plaintext passwords, and associated URLs, likely representing active sessions or frequently accessed services. The description points to a Telegram user uploading a stealer log file, a common method for distributing compromised data. The source structure of the log suggests automated collection by malware designed to harvest credentials from infected endpoints. The leak location, a cloud storage service, provided a readily accessible platform for the dissemination of this sensitive information.

The prevalence of stealer logs appearing on platforms like Telegram is a well-established threat vector. Cybersecurity research consistently highlights the ongoing efforts of threat actors to collect and monetize such data. The rapid availability of these credentials on public channels facilitates widespread exploitation, including credential stuffing attacks and direct account takeovers, posing a significant risk to individuals and organizations alike.
