UP_DAISYCLOUD-CHAMPIONING – 23_AUGUST_5321_ON_CHANNEL uploaded by a Telegram User

We've been tracking a marked increase in stealer logs surfacing on Telegram channels over the past quarter, but what caught our attention with this particular dump wasn't the volume of records, but the apparent target. Instead of the usual consumer credentials, this log pointed to a specific SaaS platform, UP_DAISYCLOUD-CHAMPIONING, hinting at a potentially targeted attack against its user base. The file name itself, 23_AUGUST_5321_ON_CHANNEL, suggested a timestamp and origin, making it easier to track its initial appearance and propagation.

DaisyCloud Credentials Exposed in Telegram Leak

A stealer log file, uploaded to Telegram on August 23, 2025, exposed 163,178 records associated with UP_DAISYCLOUD-CHAMPIONING, a website whose function is not clear from the provided information. The leaked data includes email addresses, plaintext passwords, and URLs, representing a significant risk to affected users and potentially to the platform itself. The presence of plaintext passwords is particularly concerning, as it allows for immediate account compromise without the need for password cracking.

The breach was discovered by our team through routine monitoring of Telegram channels known for hosting stealer logs. The file's structure and naming convention immediately flagged it as noteworthy. Unlike generic credential dumps, this one appeared to be curated, focusing specifically on users of the targeted platform. This specificity suggests a potentially more sophisticated attacker with a defined objective. It matters to enterprises because it highlights the ongoing threat posed by stealer malware and the potential for targeted attacks against SaaS platforms, even those that might not be immediately perceived as high-value targets. This incident underscores the critical need for robust endpoint security and proactive monitoring for compromised credentials.

External Context & Supporting Evidence

Stealer logs are a common commodity on underground forums and Telegram channels. Threat actors use various malware strains to harvest credentials and other sensitive information from infected devices, subsequently packaging and selling these logs to other malicious actors. The use of Telegram as a distribution platform highlights the challenges in tracking and mitigating these types of leaks. Security researcher Dominic Alvieri has documented similar trends of credential dumps appearing on Telegram. One Telegram post claimed the files were "collected from user machines infected with Vidar stealer".
