SunCloudNew 1122 – 6250 LogsFile.part11 uploaded by a Telegram User

We noticed an alarming upload on a public Telegram channel on February 24th, 2026, containing what appeared to be a substantial collection of endpoint and credential data. What struck us as particularly concerning was the direct exposure of plaintext passwords alongside email addresses and associated API host URLs. This isn't a typical credential stuffing dataset; it points to a more direct compromise event, likely originating from malware-infected endpoints. The sheer volume and the nature of the exposed information suggest a significant risk of account takeover and further network infiltration for any entities whose users or systems were affected.

The breach, identified as a stealer log dump, originated from a file titled "SunCloudNew 1122 – 6250 LogsFile.part11," uploaded by an anonymous Telegram user. This dump contains 16,845 records, each detailing an endpoint, an associated email address, an API host URL, and crucially, plaintext passwords. The structure of the data suggests it was exfiltrated by infostealer malware, likely harvesting credentials and system information from compromised machines. The presence of API host URLs is particularly noteworthy, as it could reveal exposed administrative interfaces or services that attackers might attempt to leverage for lateral movement or data exfiltration. The exposure of plaintext passwords bypasses the need for brute-forcing or credential stuffing, presenting an immediate and severe risk to the affected accounts.

While specific news coverage of this particular Telegram dump is limited due to its nature as a raw data leak rather than a targeted company announcement, the methodology aligns with ongoing trends in cybercrime. Infostealer malware remains a persistent threat, with researchers from groups like Mandiant and CrowdStrike frequently publishing reports on its evolving capabilities and the widespread impact of credential harvesting. The use of Telegram as a distribution channel for such data is well-documented, serving as a readily accessible marketplace for threat actors to share and monetize stolen information. The exposed API host URLs could be cross-referenced with known vulnerable services or publicly accessible endpoints to identify potential targets for further exploitation.
