HEROIC Analysts Found the Everlasting_Cloud Dump on the Dark Web

We noticed a recent upload to a public Telegram channel on February 5th, 2025, containing what appears to be a substantial stealer log. What struck us immediately was the direct exposure of plaintext passwords alongside email addresses and associated URLs, a configuration that significantly amplifies the risk of credential stuffing and account takeover across multiple platforms. The sheer volume, while not unprecedented, combined with the sensitive nature of the data, warrants immediate attention to understand the potential blast radius.

The uploaded data, identified as a stealer log originating from a Telegram user, contained 13,383 records. These records predominantly consist of email addresses, plaintext passwords, and corresponding URLs, likely representing the websites or services accessed by the compromised endpoints. The source structure suggests a typical infostealer compromise, where malware on an endpoint harvests credentials and browsing history. The presence of API hosts within the data further indicates potential exposure of programmatic access credentials, which could be leveraged for automated attacks. The leak locations are currently confined to this specific Telegram channel, but the ease of access suggests potential wider dissemination.

While specific news coverage on this particular stealer log has not yet emerged, the methodology is a recurring theme in cybersecurity incidents. Infostealer malware, often distributed through phishing or malicious downloads, continues to be a primary vector for credential harvesting. Research from various security firms consistently highlights the persistent threat of these tools, with threat actors actively monitoring and monetizing such data dumps. The direct exposure of plaintext passwords, as seen here, bypasses the need for brute-forcing or credential stuffing against hashed passwords, making the compromised accounts immediately vulnerable.

We observed a significant data leak surfacing on February 10th, 2025, attributed to a breach at "Everlasting_Cloud" and disseminated via a Telegram user. The standout characteristic of this incident is the direct availability of plaintext passwords, a critical vulnerability that bypasses many standard security mitigations. The data's composition suggests a compromise of user endpoints, leading to the exfiltration of sensitive login credentials and associated web activity. The speed at which this information appeared publicly underscores the urgency of our response.

The "Everlasting_Cloud" breach, as reported, involved the leakage of 13,383 records. The core of the exfiltrated data includes email addresses, plaintext passwords, and associated URLs. Analysis of the uploaded file indicates it's a stealer log, likely harvested by malware operating on compromised endpoints. This implies that the threat actor gained access to credentials stored or entered on these devices, potentially including those for cloud services, email providers, and other web applications. The inclusion of URLs provides context for the compromised credentials, enabling attackers to prioritize targets for account takeover. The data's current known leak location is a specific Telegram channel, but the nature of such leaks suggests rapid propagation is a high probability.

This incident aligns with ongoing trends in credential theft, where infostealers remain a potent tool for threat actors. While "Everlasting_Cloud" itself may not be a widely reported entity in mainstream news, the methodology of stealer logs is a constant concern. Security research frequently details the evolution of infostealer malware and the subsequent marketplaces where such harvested data is traded. The direct exposure of plaintext passwords, as seen in this dump, is a critical reminder of the importance of strong, unique password practices and multi-factor authentication, even for seemingly less prominent online services.

Our attention was drawn on February 8th, 2025, to a stealer log uploaded by a Telegram user, detailing a compromise affecting "Everlasting_Cloud." What immediately raised a red flag was the inclusion of plaintext passwords, a highly sensitive data type that significantly lowers the barrier for malicious actors to exploit compromised accounts. The data's structure suggests a direct compromise of endpoint credentials, rather than a database breach, and the associated URLs offer valuable reconnaissance for potential attackers.

The breach encompasses 13,383 records, primarily comprising email addresses, plaintext passwords, and URLs. The origin of this data appears to be a stealer log, indicating malware-driven credential harvesting from compromised user devices. This method allows threat actors to acquire credentials for a wide array of services accessed by the victim. The presence of URLs alongside credentials suggests that the stealer was able to capture browsing history and form submissions, providing context for the compromised accounts. The leak is currently confined to a specific Telegram channel, but the ease of access to such platforms makes broad dissemination a significant risk.

While this specific "Everlasting_Cloud" incident may not have garnered widespread media attention, the underlying threat of infostealer malware is a persistent and well-documented issue. Security advisories from various organizations frequently highlight the effectiveness of these tools in exfiltrating sensitive information, including directly exposed credentials. The direct availability of plaintext passwords, as observed in this leak, represents a critical failure in credential management and underscores the ongoing need for robust endpoint security and user education regarding secure online practices.
