We've been tracking a concerning uptick in stealer logs surfacing on Telegram channels, often peddling compromised credentials and API keys. What caught our attention this week wasn't the volume of these logs, but the specificity of the targets and the apparent automation involved in their collection and distribution. The setup here felt different because the files contained not just the usual mix of personal accounts, but also internal URLs and potential API endpoints, suggesting a more focused reconnaissance effort pre-compromise. The data had been circulating quietly, but we noticed a pattern in the naming conventions and associated chatter that pointed to a coordinated campaign.

Rogue Cloud TG: 19,763 Records Exposed via Telegram Channel

A stealer log file, dubbed RogueCloud, was uploaded by a user on Telegram on September 28, 2025, exposing 19,763 records. This breach highlights the ongoing risk posed by stealer malware and the increasing use of Telegram channels as distribution points for compromised data. The leaked data includes a mix of sensitive information, including email addresses, plaintext passwords, and internal URLs.

Our team discovered the leak while monitoring known Telegram channels frequented by cybercriminals. What made this particular log stand out was the presence of internal URLs alongside more typical credential dumps. This suggested the compromised endpoints had access to internal corporate resources, potentially providing attackers with a foothold for further exploitation. The file's name, RogueCloud, also hinted at a possible cloud-based service or application targeted by the stealer.

The exposure of plaintext passwords is particularly concerning, as it allows for immediate account takeover attacks. Furthermore, the inclusion of internal URLs provides attackers with valuable reconnaissance information, enabling them to map out internal networks and identify potential vulnerabilities. This breach underscores the importance of robust endpoint security measures, including anti-malware software and regular password resets.

The use of Telegram channels for distributing stealer logs is a growing trend, as these platforms offer anonymity and a wide reach. Security researchers have documented numerous instances of compromised data being traded and sold on Telegram, highlighting the need for proactive monitoring and threat intelligence. For example, a recent report by BleepingComputer detailed how Telegram bots are being used to automate the sale of stolen credentials and other sensitive data. This breach is a stark reminder of the persistent threat posed by stealer malware and the importance of implementing robust security measures to protect against data exfiltration.
