SunCloudNew 1363 – 400 LogsFile uploaded by a Telegram User

We noticed a recent upload on a public Telegram channel containing a stealer log file, dated December 29, 2025. This particular file, identified as "SunCloudNew 1363 – 400 Logs," immediately drew our attention due to the raw nature of the data presented. What struck us was the inclusion of plaintext passwords alongside email addresses and API host URLs, a combination that significantly elevates the risk profile of this exposure. The sheer volume of records, totaling 10,764, further underscores the potential impact on our user base and associated services.

The breach originated from a stealer log file, a common artifact of malware infections designed to exfiltrate credentials and other sensitive information from compromised endpoints. This specific log appears to have been uploaded by an anonymous Telegram user, obscuring the initial point of compromise. The exposed data includes 10,764 email addresses, plaintext passwords, and associated API host URLs. The presence of plaintext passwords is a critical vulnerability, as it bypasses any hashing or salting mechanisms, rendering them immediately usable by attackers. The API host URLs suggest that credentials for programmatic access to services might also be compromised, potentially enabling further lateral movement or unauthorized data manipulation.

While direct news coverage of this specific stealer log upload is unlikely, the broader threat landscape is well-documented. Security researchers frequently publish reports on the proliferation of stealer malware and the subsequent leakage of stolen credentials on platforms like Telegram and the dark web. For instance, recent analyses from Mandiant and CrowdStrike have detailed the evolving tactics of infostealer campaigns, highlighting their effectiveness in gaining initial access to corporate networks. The data types exposed in this incident are consistent with the typical payloads of popular stealers such as RedLine, Vidar, and Raccoon, which are readily available on underground forums.
