SunCloudNew 1362 – 550 LogsFile uploaded by a Telegram User

We noticed a concerning data leak originating from a stealer log file uploaded to Telegram on December 28, 2025. What struck us immediately was the relatively low Pwned count of 7081, suggesting a targeted or potentially smaller-scale compromise rather than a broad, indiscriminate breach. The presence of plaintext passwords, alongside email addresses and URLs, immediately flags this as a high-priority incident requiring swift action to mitigate credential stuffing and further unauthorized access. The source structure, identified as a stealer log, points towards malware-driven exfiltration, a common vector for credential harvesting.

The incident, identified as a stealer log breach, involved a file uploaded by a Telegram user on December 28, 2025. This log contained 7081 records, exposing sensitive endpoint information, email addresses, API host details, and critically, plaintext passwords. The implication of plaintext passwords is that any system using these credentials, or variations thereof, is immediately vulnerable to credential stuffing attacks. The data types suggest an attacker gained access to systems capable of harvesting login information, potentially through infostealer malware. The leak location on Telegram indicates a public or semi-public dissemination, increasing the risk of widespread exploitation.

External Context

While specific news coverage directly referencing this particular SunCloudNew 1362 incident is not yet apparent, the broader landscape of stealer log leaks is a persistent concern. Threat intelligence reports from various cybersecurity firms frequently detail the discovery and analysis of such logs on platforms like Telegram, often revealing compromised credentials for a wide array of services. Researchers have consistently highlighted the efficacy of infostealer malware in harvesting credentials, which are then frequently traded or leaked on dark web forums and public messaging applications. The ease with which these logs can be uploaded and shared amplifies the risk associated with such breaches, making proactive threat hunting for these types of artifacts crucial.
