CloudDuke
Intelligence Profile
F-Secure describes CloudDuke as a malware toolset known to consist of, at least, a downloader, a loader and two backdoor variants. The CloudDuke downloader will download and execute additional malware from a preconfigured location. Interestingly, that location may be either a web address or a Microsoft OneDrive account. Both CloudDuke backdoor variants support simple backdoor functionality, similar to SeaDuke. While one variant will use a preconfigured C&C server over HTTP or HTTPS, the other variant will use a Microsoft OneDrive account to exchange commands and stolen data with its operators.
