Upload by LOGSYNC – KeyCloud_Free_logs118 uploaded by a Telegram User

We noticed a recent upload to a public file-sharing platform, specifically "Upload by LOGSYNC," containing what appears to be a stealer log. The file, titled "KeyCloud_Free_logs118," was uploaded by a Telegram user on May 26, 2025. What struck us immediately was the inclusion of plaintext passwords alongside email addresses and URLs, a combination that significantly elevates the risk profile of this particular dataset. The relatively small pwned count of 15,654 records, while not massive in absolute terms, does not diminish the potential impact given the sensitive nature of the exposed credentials.

The breach breakdown reveals a stealer log originating from a Telegram user, containing 15,654 records. The exposed data includes email addresses, plaintext passwords, and associated URLs. The description indicates these logs likely originated from compromised endpoints, capturing API host information and user credentials. The significance of this leak lies in the direct exposure of authentication material, allowing for immediate credential stuffing attacks against other services where users may have reused passwords. The source structure points to a common malware vector, where stealer trojans exfiltrate sensitive data from infected systems.

While specific news coverage for this particular upload is limited, the broader trend of credential theft via stealer malware is a persistent concern. Security researchers frequently publish reports detailing the prevalence and evolving tactics of these threats. For instance, recent analyses by cybersecurity firms have highlighted the continued effectiveness of stealer logs in facilitating account takeovers across various platforms. The exposure of plaintext passwords, even in smaller datasets, remains a critical vector for attackers seeking to exploit password reuse and gain unauthorized access to user accounts and potentially enterprise systems if corporate credentials are among the leaked data.
