TXT Cloud – LOGS_900PCS – 28 October 2025 uploaded by a Telegram User

We noticed a recent upload to a public Telegram channel containing a stealer log file, dated October 28, 2025. The dataset, identified as "TXT Cloud – LOGS_900PCS," appears to be a compilation of compromised endpoint data. What struck us was the inclusion of plaintext passwords alongside email addresses and API host URLs, indicating a direct compromise of user credentials rather than a mere enumeration of publicly available information. This type of data exposure can significantly amplify the attack surface for affected entities.

The stealer log, uploaded by an anonymous Telegram user, contained 22,590 records. Analysis of the data structure reveals a consistent format, likely originating from a single infostealer malware variant. The primary data types exposed are email addresses, plaintext passwords, and associated API host URLs. This suggests that the compromised endpoints were actively being used to access services that leverage API authentication, making the leaked credentials particularly potent for further exploitation. The direct exposure of plaintext passwords is a critical vulnerability, bypassing any hashing or salting mechanisms that might have been in place on the target systems.

While this specific incident appears to be a standalone leak from a Telegram channel, the broader phenomenon of infostealer logs circulating on such platforms is a persistent concern within the cybersecurity landscape. Threat actors frequently leverage these channels to trade or sell compromised credential dumps, facilitating further attacks such as account takeover, credential stuffing, and targeted phishing campaigns. The ease with which such data can be accessed and weaponized underscores the ongoing challenges in preventing endpoint compromises and securing sensitive user information.
