CROWNLOGCLOUD – 700 LOGS uploaded by a Telegram User

We noticed a concerning aggregation of credentials and endpoint identifiers surfacing on a public Telegram channel in late December 2022. The discovery, stemming from a routine scan of known stealer log repositories, revealed a dataset of approximately 7,000 records. What struck us as particularly noteworthy was the inclusion of plaintext passwords alongside email addresses and API host URLs, suggesting a direct compromise of user credentials rather than a more sophisticated credential stuffing attack. The sheer volume and directness of the exposed information warrant immediate attention to potential downstream impacts.

The breach, identified on December 27, 2022, originated from a single stealer log file uploaded by an anonymous Telegram user. This file contained 7,008 records, each detailing endpoint information, email addresses, and crucially, plaintext passwords. The presence of API host URLs further indicates that these credentials may have been used to access specific services or applications. The source structure of the leak points to a common malware variant, likely a credential stealer, that exfiltrated data from compromised endpoints. The leak location, a public Telegram channel, signifies a broad dissemination of this sensitive information, increasing the attack surface for malicious actors.

While this specific incident involving "CROWNLOGCLOUD" and its 700 logs uploaded by a Telegram user does not appear to have generated widespread news coverage at the time of its discovery, it aligns with a persistent trend of credential exposure through stealer malware. Numerous cybersecurity research firms, including Mandiant and CrowdStrike, have consistently reported on the proliferation of credential stealers and the subsequent leakage of stolen data on dark web forums and public messaging platforms. The OSINT landscape frequently highlights the ongoing challenges in combating these types of attacks, where compromised credentials are a primary vector for further lateral movement and data exfiltration within enterprise environments.
