UP_DAISYCLOUD-CHAMPIONING – 29_JULY_5481_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 caught our attention with this particular leak wasn't the volume of records, but the specific combination of data points exposed. The data included not just usernames and passwords, but also internal API host URLs, potentially providing a blueprint for deeper system access. The setup here felt different because it seemed to be focused on a specific cloud service, rather than a broader sweep of credentials. The data had been circulating quietly, but we noticed it being referenced in other Telegram channels known for trading in access to compromised systems.

DaisyCloud Credentials Exposed Via Telegram

A Telegram user uploaded a stealer log file on July 29, 2025, exposing 185,910 records associated with a service we're calling UP_DAISYCLOUD-CHAMPIONING. This file contained a mix of sensitive information, including email addresses, plaintext passwords, and crucially, internal API host URLs. We believe this combination of data poses a significant risk, potentially allowing attackers to bypass typical authentication measures and directly access backend systems.

The breach was discovered by our team while monitoring Telegram channels known for hosting and distributing stealer logs. What made this stand out was the clear targeting of a specific cloud service, indicated by the consistent naming conventions and the presence of internal API endpoints. This suggests a focused effort to compromise accounts associated with this particular platform. It matters to enterprises now because it highlights the ongoing risk of stealer logs being used to target specific SaaS applications, potentially allowing attackers to move laterally within an organization's cloud infrastructure.

• Total records exposed: 185,910
• Types of data included: Email Addresses, Plaintext Passwords, URLs (internal API endpoints)
• Sensitive content types: Potentially PII depending on the nature of the "DaisyCloud" service.
• Source structure: Stealer log file
• Leak location: Telegram channel
• Channel Name: UP_DAISYCLOUD-CHAMPIONING
• Date Leaked: 29-Jul-2025

External Context & Supporting Evidence

Stealer logs remain a persistent threat vector, as highlighted in recent reports from CrowdStrike and Mandiant. These reports detail how readily available stealer logs are on platforms like Telegram, often offered for sale or traded within specific communities. The plaintext storage of passwords is a particularly egregious security lapse, as noted by security researcher Troy Hunt on his blog, highlighting the continued failure of some services to implement basic security measures. The presence of API host URLs within the leaked data further amplifies the risk, as these endpoints can be leveraged to bypass traditional authentication methods and gain direct access to backend systems.
