LogsDiller Cloud_Free_187_180 uploaded by a Telegram User

We noticed a concerning upload on a popular Telegram channel on December 8th, 2025. The file, identified as a stealer log, contained a significant volume of sensitive information harvested from compromised endpoints. What struck us immediately was the inclusion of plaintext passwords alongside email addresses and API host details, indicating a direct bypass of common credential protection mechanisms. The sheer volume, while not enterprise-shattering, represents a tangible risk to individual user accounts and potentially downstream systems if these credentials are reused.

The breach originated from a stealer log file, designated "LogsDiller Cloud_Free_187_180," uploaded by an anonymous Telegram user. This log contained 3,190 distinct records, each comprising an email address, a plaintext password, and associated URLs, likely representing accessed services or API endpoints. The presence of plaintext passwords is a critical vulnerability, suggesting that the stealer malware was effective in exfiltrating credentials directly from memory or insecure storage. The data types exposed—email addresses, plaintext passwords, and URLs—paint a clear picture of credential stuffing and account takeover as primary threat themes. The source structure implies a collection of individual endpoint compromises rather than a single, large-scale database breach.

While this specific incident has not garnered widespread mainstream news coverage, the methodology aligns with prevalent threat actor tactics observed in the OSINT landscape. Numerous cybersecurity research reports from firms like Mandiant and CrowdStrike have detailed the increasing sophistication of infostealer malware and its role in facilitating initial access for more complex attacks. The exploitation of Telegram channels for data dissemination is a well-documented phenomenon, allowing threat actors to distribute compromised data rapidly and with a degree of anonymity. The nature of stealer logs also suggests a potential for these credentials to be weaponized in credential stuffing campaigns against other services, a tactic frequently highlighted in threat intelligence briefings.
