SunCloudNew 1114 – 6200 LogsFile.part2 uploaded by a Telegram User

We noticed an alarming upload on a popular Telegram channel on February 17th, 2026, containing a substantial stealer log file. What struck us immediately was the sheer volume of compromised credentials and endpoint information, suggesting a widespread compromise rather than a targeted attack. The file, identified as "SunCloudNew 1114 – 6200 LogsFile.part2," points to a significant data exfiltration event that warrants immediate attention and investigation across our user base.

The breach originated from a stealer malware, commonly deployed to harvest credentials and sensitive information from infected endpoints. The uploaded file contained 60,094 records, each potentially representing a unique compromised user. The exposed data types include email addresses, plaintext passwords, and associated URLs, indicating that threat actors gained direct access to user accounts and potentially the services they accessed. The source structure of the leak suggests a log file compiled by the stealer, detailing the compromised endpoints and the data it successfully extracted. The leak location, a public Telegram channel, signifies the intent to disseminate this information widely, likely for resale or further exploitation.

While specific news coverage directly attributing this leak to a particular organization is not yet apparent, the nature of stealer logs often implies opportunistic attacks targeting individuals or smaller entities that may not have robust endpoint security. Open-source intelligence (OSINT) on Telegram channels frequently reveals such caches of stolen credentials, which are then used in credential stuffing attacks against various platforms. Security research from firms like Mandiant and CrowdStrike has consistently highlighted the persistent threat posed by infostealers, detailing their evolving tactics and the significant downstream impact of credential exposure.
