UP_DAISYCLOUD-CHAMPIONING – 28_JUNE_5212_ON_CHANNEL uploaded by a Telegram User

We’re seeing an uptick in stealer logs surfacing on Telegram channels, often targeting specific applications or services. What initially seems like a standard credential dump can, upon closer inspection, reveal targeted campaigns aimed at specific sectors. We first noticed this particular breach through chatter on a dark web forum, where a user highlighted a Telegram post containing a file named UP_DAISYCLOUD-CHAMPIONING – 28_JUNE_5212_ON_CHANNEL. What really struck us wasn't the volume of records, but the specificity of the naming convention and the unique combination of data points within the file. The data had been circulating quietly since June 28, 2025, but its potential impact on organizations using DaisyCloud services warranted immediate investigation.

DaisyCloud Credentials Exposed in Telegram Leak

A stealer log file, uploaded to a Telegram channel by an unknown user, exposed 241,166 records containing sensitive information related to DaisyCloud, a cloud-based platform. This breach came to our attention through mentions on a dark web forum, prompting us to investigate the linked Telegram post. The file’s naming convention suggested a targeted collection effort, and the data contained within confirmed our suspicions. This incident underscores the persistent threat posed by stealer logs and their potential to compromise cloud environments. Understanding the scope and nature of the exposed data is crucial for enterprises to mitigate potential risks.

• Total records exposed: 241,166
• Types of data included: Email Addresses, Plaintext Passwords, URLs, API host, Endpoints
• Sensitive content types: User credentials, potentially granting unauthorized access to DaisyCloud resources.
• Source structure: Stealer log file, format not specified.
• Leak location(s): Telegram channel.

The emergence of this DaisyCloud-related stealer log aligns with a broader trend of threat actors leveraging Telegram channels to distribute compromised data. Security researchers have noted an increase in the sale and sharing of stealer logs on such platforms, highlighting the need for enhanced monitoring and proactive threat hunting. As BleepingComputer reported earlier this year, Telegram's ease of use and anonymity features make it an attractive platform for cybercriminals to distribute stolen data and coordinate malicious activities. One Telegram post claimed the files were "collected from compromised machines running cloud management software." This breach is a reminder of the increasing sophistication of stealer malware and the importance of robust endpoint security measures.
