Abstract:
A system for providing a steganographic message to a hypervisor may include a memory having computer readable instructions and one or more processors for executing the computer readable instructions. The computer readable instructions may include identifying a plurality of selected bits of usage data of a virtual machine. Further according to the computer readable instructions, a desired message may be encoded as a steganographic message stored in the plurality of selected bits in the usage data. Encoding the desired message may include manipulating one or more resources of the virtual machine to cause a change in the plurality of selected bits in the usage data. The usage data may be provided to the hypervisor, and the steganographic message may be observable in the usage data.
