Pegasus Cloud PegasusCloud uploaded by a Telegram User

We noticed an unusual surge in traffic originating from a known stealer distribution channel on October 20, 2025. The uploaded data, identified as a stealer log file, presented a concerning volume of compromised credentials and endpoint information. What struck us immediately was the relatively low pwned count juxtaposed with the plaintext nature of the passwords, suggesting a targeted or opportunistic acquisition rather than a broad credential stuffing campaign. The inclusion of API hosts alongside user credentials warrants particular attention, as it points towards potential lateral movement or unauthorized access to backend services.

The incident, logged as a stealer log breach, involved the exfiltration of 77,945 records. Analysis of the uploaded file revealed a structured format, likely originating from a single endpoint infected by a stealer malware. The exposed data includes email addresses, plaintext passwords, and associated URLs, which in this context are identified as API hosts. This combination is particularly potent, as it provides attackers with direct access to user accounts and the infrastructure they interact with. The leak location, a Telegram user upload, indicates a public or semi-public dissemination of the compromised data, increasing the risk of further exploitation.

While this specific Pegasus Cloud incident has not yet garnered widespread media attention, the broader landscape of stealer malware continues to be a significant concern. Research from firms like Mandiant and CrowdStrike consistently highlights the evolving tactics of stealer operators, who are increasingly focusing on harvesting credentials for cloud services and API endpoints. The ease with which such logs can be shared on platforms like Telegram underscores the persistent challenge of preventing the monetization of stolen data.

Our attention was drawn to a significant data dump on October 20, 2025, originating from a Telegram channel that frequently disseminates compromised credential sets. This particular upload, identified as a stealer log, contained a substantial number of records that immediately flagged as high-risk due to the inclusion of plaintext passwords. The sheer volume, while not record-breaking, is concerning given the direct accessibility of the credentials and associated endpoint information. The presence of API host details alongside user credentials suggests a sophisticated attack vector, potentially aimed at compromising internal systems or cloud infrastructure.

This breach, categorized as a stealer log compromise, has resulted in the exposure of 77,945 records. The data types include email addresses, plaintext passwords, and URLs, which appear to represent API endpoints. The source structure of the data points to a single stealer infection, where malware systematically harvested information from an endpoint. The leak location, a Telegram user upload, signifies that this data is now readily available to a wider audience of malicious actors. The implications are significant, as attackers can leverage these credentials to gain unauthorized access to user accounts and potentially pivot to other systems through the exposed API endpoints.

While this specific instance of Pegasus Cloud data being leaked via Telegram has not made headlines, the proliferation of stealer malware is a constant threat. Security advisories from government agencies and cybersecurity firms frequently detail the impact of such tools, which are instrumental in credential harvesting. The ease of distribution through platforms like Telegram means that even seemingly isolated incidents can contribute to a larger ecosystem of cybercrime, where stolen credentials are traded and exploited.

We've identified a data leak dated October 20, 2025, uploaded by a Telegram user, which appears to be a stealer log file. What's particularly noteworthy is the direct exposure of plaintext passwords alongside user email addresses and API host URLs. This isn't a case of hashed credentials being brute-forced; rather, it's a direct acquisition of sensitive login information. The structured nature of the log suggests a single point of compromise, likely an endpoint infected with malware designed to exfiltrate such data. The inclusion of API hosts is a critical detail, hinting at a potential pathway for attackers to access backend services or cloud infrastructure.

The breach, originating from a stealer log, has impacted 77,945 records. The exposed data encompasses email addresses, plaintext passwords, and URLs, which we've identified as API endpoints. The source structure indicates a single, compromised endpoint from which the stealer malware extracted this information. The leak location, a Telegram user upload, means this data is now accessible to a broad spectrum of threat actors. This poses a significant risk, as attackers can directly use these credentials to access user accounts and potentially exploit the exposed API endpoints for further malicious activities, such as data exfiltration or unauthorized system access.

There is no immediate widespread news coverage of this specific Pegasus Cloud leak. However, the broader threat landscape of stealer malware is well-documented. Cybersecurity research consistently points to the effectiveness of these tools in harvesting credentials for various online services, including cloud platforms. The use of Telegram as a distribution channel for such logs is a persistent issue, enabling rapid dissemination and monetization of compromised data.
