LogsDiller Cloud_Free_19 uploaded by a Telegram User

We noticed a new entry in our threat intelligence feeds on December 8th, 2025, detailing a substantial upload to a public Telegram channel. The source, identified as "LogsDiller Cloud_Free_19," presented a collection of stealer logs, a common vector for credential harvesting. What struck us was the relatively low but still significant pwned count of 877 records, coupled with the inclusion of plaintext passwords, a critical vulnerability that bypasses typical hashing protections. This discovery immediately flagged a potential for unauthorized access to a variety of online services and internal systems if any of the compromised credentials were reused.

The breach originated from a stealer log file, uploaded by an anonymous Telegram user. This log captured data from 877 compromised endpoints, revealing a mix of sensitive information including email addresses, plaintext passwords, and associated URLs. The structure of the data suggests a direct capture of user input or browser credential storage, indicating a successful malware infection on the affected endpoints. The implications are significant, as plaintext passwords offer immediate access to accounts, bypassing any multi-factor authentication that might be in place if the user has not implemented it. The leak location being a public Telegram channel amplifies the risk, making the data readily accessible to a broad audience of malicious actors.

While this specific leak has not garnered widespread mainstream news coverage, the methodology aligns with ongoing trends in credential stuffing and account takeover attacks. Security researchers have consistently highlighted the prevalence of stealer malware, such as RedLine or Raccoon Stealer, which are frequently distributed via phishing campaigns and exploit kits. The ease with which these logs can be exfiltrated and shared on platforms like Telegram underscores the persistent threat posed by endpoint compromise. Organizations should remain vigilant for any indicators of compromise related to credential harvesting tools and prioritize user education on secure password practices and the dangers of phishing.
